    2009-01-01

    Background: The role of radiographers with respect to image interpretation within clinical practice is well recognised. It is the expectation of the professional, regulatory and academic bodies that upon qualification, radiographers will possess image interpretation skills. Additionally, The College of Radiographers has asserted that its aspiration is for all radiographers to be able to provide an immediate written interpretation on skeletal trauma radiographs by 2010. This paper explores the readiness of radiography education programmes in the UK to deliver this expectation. Method: A postal questionnaire was distributed to 25 Higher Education Institutions in the UK (including Northern Ireland) that provided pre-registration radiography education as identified from the Society and College of Radiographers register. Information was sought relating to the type of image interpretation education delivered at pre- and post-registration levels; the anatomical range of image interpretation education; and education delivery styles. Results: A total of 19 responses (n = 19/25; 76.0%) were received. Image interpretation education was included as part of all radiographer pre-registration programmes and offered at post-registration level at 12 academic centres (n = 12/19; 63.2%). The anatomical areas and educational delivery methods varied across institutions. Conclusion: Radiography education providers have embraced the need for image interpretation education within both pre- and post-registration radiography programmes. As a result, UK education programmes are able to meet the 2010 College of Radiographers aspiration.

    To examine student incivility in radiography classrooms by exploring the prevalence of uncivil behaviors along with the classroom management strategies educators use to manage and prevent classroom disruptions. A survey was designed to collect data on the severity and frequency of uncivil student behaviors, classroom management strategies used to address minor and major behavioral issues, and techniques to prevent student incivility. The participants were educators in radiography programs accredited by the Joint Review Committee on Education in Radiologic Technology. Findings indicated that severe uncivil student behaviors in radiography classrooms do not occur as often as behaviors classified as less severe. Radiography educators in this study used a variety of strategies and techniques to manage and prevent student incivility; however, radiography educators who received formal training in classroom management reported fewer incidents of student incivility than those who had not received formal training. The participants in this study took a proactive approach to addressing severe behavioral issues in the classroom. Many radiography educators transition from the clinical environment to the classroom setting with little to no formal training in classroom management. Radiography educators are encouraged to attend formal training sessions to learn how to manage the higher education classroom effectively. Student incivility is present in radiography classrooms. This study provides a foundation for future research on incivility. ©2017 American Society of Radiologic Technologists.

    Objectives: To describe and review the Delphi technique as a tool for radiographers engaged in mixed-methods research whereby agreement is required on the proficiencies needed by educational programmes for pre- and post- registration radiographers. This is achieved through a description offering a brief history of the technique. Through a literature search, radiography education research using this technique is identified. A protocol for a research project using the technique is presented. Using this worked example, advantages and disadvantages of the method are explored including sampling of participants, sample size, number of rounds and methods of feedback. Key findings: There are limited examples of the use of the Delphi technique in radiography literature including considerations on how to select experts and panel size. Conclusion: The Delphi technique is a suitable method for establishing collective agreement in the design of radiography educational interventions. Additional research is needed to deepen this evidence-based knowledge. - Highlights: • The Delphi Technique is used to gain collective agreement in forecasting healthcare education priorities. • There is increase of the use of the technique in healthcare education literature. • There are some examples of the technique in radiography education research. • A worked example of this technique is provided to critically evaluate this tool.

    Purpose: To establish an understanding of radiography education across Europe by surveying higher education institutions registered as affiliate members of the European Federation of Radiography Societies (EFRS). Method: An online survey was developed to ascertain data on: curricula, duration, credit load, accreditation requirements, staff qualifications, staff and student exchange opportunities, and availability of postgraduate programmes. Responses were identifiable in terms of educational institution and country. All 46 affiliated educational institutions were invited to participate in the survey. Descriptive and thematic analyses are reported. Results: A response rate of 89.1% (n = 41) was achieved from educational institutions representing 21 countries. The majority of institutions (63.4%) offer a combined Medical Imaging, Radiotherapy and Nuclear Medicine programme; dedicated Medical Imaging programmes are offered by 14 institutions (34.2%); dedicated Radiotherapy programme by one institution (2.4%), and a dedicated Nuclear Medicine programme by only three institutions (6.5%). The Bologna (Bachelor) cycle has been adopted by 90.2% of responding institutions. The majority of institutions (53.7%) indicated programmes of 3 years in duration, others stated 3.5–4 years. Only 14.6% of institutions require ‘International Level’ accreditation for the Bachelors radiography programme. Postgraduate programmes were not offered by 26.8% of institutions and a deficit in Doctoral status for radiography educators was identified. Conclusions: The Bologna (Bachelor) cycle for radiography education has been adopted across the majority of institutions, however, full alignment remains a priority. Postgraduate radiography education opportunities across Europe appear to be insufficient and further investigation of radiography accreditation processes is justified to ensure harmonisation of practice. - Highlights: • The majority of institutions are compliant with the

    Digital radiography (DR) is one of several new products that have changed our work processes from hard copy to digital formats. The transition from analog screen-film radiography to DR requires thorough user education because of differences in image production, processing, storage and evaluation between the forms of radiography. Without adequate education, radiologic technologists could unknowingly expose children to higher radiation doses than necessary for adequate radiograph quality. To evaluate knowledge about image quality and dose management in pediatric DR among radiologic technologists in the U.S. This communication describes a survey of 493 radiologic technologists who are members of the American Society of Radiologic Technologists (ASRT) and who evaluated the current state of radiological technologist education in image quality and dose management in pediatric DR. The survey included 23 survey questions regarding image acquisition issues, quality assurance, radiation exposure and education in DR of infants and children. Radiologic technologists express many needs in areas of training and education in pediatric DR. Suggested improvements include better tools for immediate feedback about image quality and exposure, more information about appropriate technique settings for pediatric patients, more user-friendly vendor manuals and educational materials, more reliable measures of radiation exposure to patients, and more regular and frequent follow-up by equipment vendors. There is a clear and widespread need for comprehensive and practical education in digital image technology for radiologic technologists, especially those engaged in pediatric radiography. The creation of better educational materials and training programs, and the continuation of educational opportunities will require a broad commitment from equipment manufacturers and vendors, educational institutions, pediatric radiology specialty organizations, and individual imaging specialists.

    Wareing, A.K.; Henderson, I.

    2015-01-01

    Introduction: There is a paucity of evidence in diagnostic radiography evaluating a career path into industrial imaging despite several higher education institutes stating this route as a career option on graduation. The link between a career in industrial radiography and diagnostic routes is unknown although there are anecdotal examples of individuals transferring between the two. Successfully obtaining a first post job following graduation in diagnostic radiography can be challenging in the current financial climate. A partnership was formed with an energy sector company that offered non-destructive testing/non-destructive evaluation (NDT/NDE) employing industrial radiographic technicians. Method: As an initial pilot, 5 (n = 5) final year diagnostic radiography students visited an industrial radiography site and underwent theoretical and practical training. Following this placement they engaged in a focus group and the student perceptions/responses were explored and recorded. Results: Common themes were identified and categorised via a thematic analysis. These were; radiation safety, physics and technology, widening access, graduate attributes/transferable skill sets and working conditions. Conclusion: Student discussion focussed around the benefits of working conditions in healthcare, the value of technology, safety and physics education in alternative placements and the transferability of skills into other/industrial sectors (e.g. NDT/NDE). Contemporary practice placements are a useful pedagogical approach to develop complex conceptual theoretical constructs, such as radiation physics. An in depth evaluation between the two industries skill sets is postulated. Additionally, this could offer alternative/emerging roles to interested diagnostic radiographers potentially meeting the skill shortage in industrial radiography. - Highlights: • Research in this area is novel. No evidence could be found to evaluate the links. • Students had theoretical

    Radiographic apparatus is described in which a thin planar slice of the body is examined by a swath of penetrating radiation such as X-rays. Collimators are provided for collimating the radiation after it has passed through the body into a set of beams which are directed into respective detectors. The swath of radiation, the collimeters and the detectors are orbited in the plane of the slice so that the beams pass through the body from many different angular directions. Means are provided for additionally displacing at least the collimators relative to the source so that the relative position of the beams and gaps between the beams are changed during the orbital movement

    Purpose: This study investigated the impact of integrating podcasts/audio file downloads and use of an electronic voting system (EVS) on a previously traditionally taught module. Both student (direct entry and mature) and staff satisfaction with the modified structure were evaluated. Method: An interim student evaluation was undertaken during the module, to provide formative data to the module leader about student opinion of the teaching methods and learning technologies. An end of module questionnaire was given to students and staff on the teaching team. Results: From the interim evaluation, given the option of returning to the traditional delivery method, 77.5% of students agreed that the module should continue to run in its blended format. The final evaluation discovered no differences in the behaviour of direct entry students compared to mature students. Both groups accessed the podcasts easily, generally at home, and spent longer studying than if blended learning technologies had not been used. It was discovered that 16% of the mature and 24% of the direct entry students would have preferred lectures to podcasts, although the students were positive about the flexibility offered. Both groups of students were virtually unanimous on the benefits of the EVS to support learning. Conclusion: The researchers concluded that the learning technologies did not create barriers for either student group, and that students' engagement with their learning and level of classroom interactivity were both increased when compared with the previous traditional delivery. The researchers are confident that the described combination of teaching delivery methods is a successful way of allowing small group work to continue with large cohorts.

    Caruana, Carmel J.; Plasek, Jaromir

    2006-01-01

    Purpose: To develop an inventory of biomedical physics elements-of-competence for diagnostic radiography education in Europe. Method: Research articles in the English literature and UK documentation pertinent to radiography education, competences and role development were subjected to a rigorous analysis of content from a functional and competence analysis perspective. Translations of radiography curricula from across Europe and relevant EU legislation were likewise analysed to ensure a pan-European perspective. Broad Subject Specific Competences for diagnostic radiography that included major biomedical physics components were singled out. These competences were in turn carefully deconstructed into specific elements-of-competence and those elements falling within the biomedical physics learning domain inventorised. A pilot version of the inventory was evaluated by participants during a meeting of the Higher Education Network for Radiography in Europe (HENRE), held in Marsascala, Malta, in November 2004. The inventory was further refined taking into consideration suggestions by HENRE members and scientific, professional and educational developments. Findings: The evaluation of the pilot inventory was very positive and indicated that the overall structure of the inventory was sensible, easily understood and acceptable - hence a good foundation for further development. Conclusions: Use of the inventory by radiography programme leaders and biomedical physics educators would guarantee that all necessary physics elements-of-competence underpinning the safe, effective and economical use of imaging devices are included within radiography curricula. It will also ensure the relevancy of physics content within radiography education. The inventory is designed to be a pragmatic tool for curriculum development across the entire range of radiography education up to doctorate level and irrespective of whether curriculum delivery is discipline-based or integrated, presentation

    The validity of a non-fluoroscopic fixed-flexion radiographic acquisition and analysis protocol for measurement of joint space width (JSW) in knee osteoarthritis is determined. A cross-sectional study of 165 patients with documented knee osteoarthritis participating in a multicenter, prospective study of chondroprotective agents was performed. All patients had posteroanterior, weight-bearing, fixed-flexion radiography with 10 caudal beam angulation. A specially designed frame (SynaFlexer) was used to standardize the positioning. Minimum medial and lateral JSW were measured manually and twice by an automated analysis system to determine inter-technique and intra-reader concordance and reliability. A random subsample of 30 patients had repeat knee radiographs 2 weeks apart to estimate short-term reproducibility using automated analysis. Concordance between manual and automated medial JSW measurements was high (ICC=0.90); lateral compartment measurements showed somewhat less concordance (ICC=0.72). There was excellent concordance between repeated automated JSW measurements performed 6 months apart for the medial (ICC=0.94) and lateral (ICC=0.86) compartments. Short-term reproducibility for the subsample of 30 cases with repeat acquisitions demonstrated an average SD of 0.14 mm for medial JSW (CV=4.3%) and 0.23 mm for lateral JSW (CV=4.0%). Fixed-flexion radiography of the knee using a positioning device provides consistent, reliable and reproducible measurement of minimum JSW in knee osteoarthritis without the need for concurrent fluoroscopic guidance.

    2012-01-01

    Purpose: Having access to a library of radiological images in the university setting is important for teaching and learning in diagnostic radiography. Modern modalities such as PETCT create data volumes rather than single static 2D images. A PACS repository of images alone does not constitute a teaching library without some text based searchable index. A review of several options for acquiring a digital teaching library (DTL) of such indexed DICOM data is presented. Discussion: The data protection principles, current guidance and potential methods for migrating and cleansing large quantities of DICOM data from a clinical PACS prior to transfer to a university setting is discussed. The chosen method is described and the important enabling technology identified. Various methods of index construction are outlined and a method of migrating and cleansing HL7 data from a clinical RIS described. Results: Three terabytes of de-normalised DICOM image files were cleansed of patient, staff and geographic identifiers, within the header tags and pixel data. These files were then migrated to an educational PACS hosted at a university. A searchable index database was created based on 90,200 reports and associated data, and 886,263 DICOM headers to enable meaningful results to be found from the 51,304 unique patient specific cases. Conclusion: A large DTL in the university setting using PACS technology is becoming a valuable resource for teaching, learning and assessment.

    The relative clinical value of magnification compared with conventional radiography for skeletal applications is presented qualitatively. The presentation is based on the authors' experience with over 25,000 cases in which magnification has been used. For most areas in which magnification (optical or geometric) proves useful, subtle abnormalities of clinical importance are present at bone surfaces or at host-lesion interfaces. This is particularly true for arthritis and metabolic and infectious disorders of bone. In additional instances, serial assessment of the progression of disease or its response to therapy is enhanced by magnification. When gross abnormalities are present, as in most instances of trauma and bone dysplasia, the findings are obvious on conventional radiography, and magnification is not necessary. Thus, the magnification techniques appear to provide important diagnostic information, depending upon the anatomic part that is studied and the clinical question that is posed. It is also apparent that the demonstration of subtle skeletal abnormalities to clinical colleagues for educational purposes is greatly enhanced by magnification radiography

    Introduction: How mammography is incorporated into undergraduate (UG) radiography training may influence student perception of the speciality and its potential as a future career option. An overview is provided of the academic and clinical content of UG radiography courses relating to mammography across the UK. Methods: Using mixed methods and an iterative, inductive approach supplying quantitative and qualitative data, we identify any variations and discuss possible causes which may help influence future training strategies. A self-designed questionnaire containing open and closed questions was sent online using SurveyMonkey™ to course leaders of all Higher Education Institutions (HEIs) offering BSc (Hons) Diagnostic Radiography courses in the UK. Responses were analysed for trends which were further explored by semi structured telephone interviews. These were transcribed and evaluated using a thematic analysis, the themes being categorised and coded. Results: 19 of 24 (79%) HEIs responded to the questionnaire. Follow up telephone interviews were conducted with five course leaders to further explore themes. Academic teaching ranged from 3 to 25 h over the 3 year course. Compared to other specialities 10 (53%) HEIs spent less time on mammography with 12 (63%) citing HCPC standards as the reason. 11 (65%) HEIs sent students on mammography placements, 2 (12%) sent females only. Placement times ranged between 2 days and 2 weeks. Influences included availability of expert teaching and relationship with clinical departments. Conclusion: There is variation in undergraduate exposure to mammography. Students views should be sought to add validity to these findings - Highlights: • A summary of undergraduate (UG) breast imaging in the UK. • Themes around the delivery of UG breast imaging education in university and practice. • Opinions of UG course leaders and other stakeholders about UG breast imaging education. • There is a variation across UK universities in

    Aim: It is essential that all health professionals who come into contact with patients with terminal diagnoses are equipped to effectively and competently provide end of life care. This study aims to investigate the manner in which Higher Education Institutions address this requirement with their programmes of pre-registration therapeutic radiography education. Method: A structured survey was administered electronically to all UK universities with responsibility for therapeutic radiography education. The scope of the survey addressed mode and duration of end of life care education, its location, curricular assessment, identifiable barriers and best practice. Results: All respondents confirmed the presence of dedicated end of life care education within their curriculum. Variation in the duration and location of this education is reported as are approaches to assessment of associated skills and knowledge. Analysis of respondent commentary has identified three themes-preparedness for the clinical role, dissonance between technology and care, and holistic approaches to course design. Conclusion: Respondents have highlighted the importance of end of life care instruction with their programmes of study and identified aspects of the mode and duration of its delivery. Inclusion of this aspect of study may be problematic in the face of competing demands arising from the volume and complexity of the curriculum. Practical experience of end of life care predominantly occurs within the radiotherapy department, although there is scope to explore opportunities within the hospice and community care setting. - Highlights: • Effective end of life care training within radiotherapy radiography programmes is necessary. • Universities confirm the inclusion of end of life care training in their curriculum. • Variations in contact time and mode of delivery are reported. • The majority of end of life care practice experience is gained within the radiotherapy department. • Wider

    Understanding the complexity of the patient-practitioner interaction is a challenging area for radiography students early in their programmes. A small scale research project was undertaken to develop blended learning resources for the teaching of patient care to radiography students. Its purpose was to utilise experiences gathered from interviews with ex-patients to produce video clips of patient-practitioner interactions so that students might gain some insight into the reality of the clinical setting, thus enabling them to link theory with practice. A total of eight interviews with ex-patients were carried out and the transcripts used to generate scripts which were enacted and filmed by a professional acting company. Thematic analysis of the study data initiated the generation of scenarios, which formed the basis of the videos. Twelve scenes showing patient-practitioner interactions in various parts of a medical imaging department and four 'talking heads' clips were produced. These were loaded onto the university's virtual learning environment and made available for viewing together with self-test and evaluation questionnaires. A pilot study was carried out; evaluation of the videos by second year student radiographers was positive. The main study was carried out using first year students with similarly positive findings and the videos are now publically available for teaching purposes. Further work in this promising area of e-learning could further utilise patients' experiences, and using the same technology, might offer students of other professions the opportunity to gain vicarious experience prior to their first encounters with patients and the general public. In conclusion, research leading to the production of simulations of real-life patient-practitioner interactions delivered using blended learning is a useful pedagogical tool in the education of radiography students.

An original survey instrument was created by selecting items from 3 instruments used in prior research and adding unique questions designed to elicit demographic data from faculty. The sample included a national dataset of radiography faculty members employed in Joint Review Committee on Education in Radiologic Technology-accredited programs in the United States. Findings showed that faculty perceptions of online course effectiveness are not affected significantly by faculty position, type of institution, faculty age, or years of teaching experience. Positive perceptions of the effectiveness of online courses moderately increased with years of teaching online courses, number of online courses taught in the past 5 years, and perceived competence with the use of technology. Faculty satisfaction with interaction in online courses moderately increased as the years of teaching online courses increased. However, the number of years of teaching online courses was not related to faculty satisfaction with teaching online courses or faculty satisfaction with institutional support. Online technology acceptance had a moderately positive relationship with perceived ease of use and a strong positive relationship with perceived usefulness of online technology. In addition, the use of technology-enhanced learning methods had a strong positive relationship with technological self-efficacy. Radiography faculty perceptions of the effectiveness of online courses improved with experience in teaching online courses and competence with use of technology. Perceived ease of use and perceived usefulness of online technology were related directly to online technology acceptance. Furthermore, faculty members with technological self-efficacy were more likely to use technology-enhanced learning methods in the online environment.

    Digital Radiography is a big part of diagnostic radiology. Because uncorrected digital radiography image supported false effect of Patient’s health care. We must be manage the correct digital radiography image. Thus, the artifact images can have effect to make a wrong diagnosis. We report types of occurrence by analyzing the artifacts that occurs in digital radiography system. We had collected the artifacts occurred in digital radiography system of general hospital from 2007 to 2014. The collected data had analyzed and then had categorize as the occurred causes. The artifacts could be categorized by hardware artifacts, software artifacts, operating errors, system artifacts, and others. Hardware artifact from a Ghost artifact that is caused by lag effect occurred most frequently. The others cases are the artifacts caused by RF noise and foreign body in equipments. Software artifacts are many different types of reasons. The uncorrected processing artifacts and the image processing error artifacts occurred most frequently. Exposure data recognize (EDR) error artifacts, the processing error of commissural line, and etc., the software artifacts were caused by various reasons. Operating artifacts were caused when the user did not have the full understanding of the digital medical image system. System artifacts had appeared the error due to DICOM header information and the compression algorithm. The obvious artifacts should be re-examined, and it could result in increasing the exposure dose of the patient. The unclear artifact leads to a wrong diagnosis and added examination. The ability to correctly determine artifact are required. We have to reduce the artifact occurrences by understanding its characteristic and providing sustainable education as well as the maintenance of the equipments.

    Ethics and values are increasingly significant aspects of patient-centred healthcare. While it is widely agreed that ethics and values are essential for healthcare delivery, there is also an acknowledgement that these are areas that are challenging to teach. The purpose of this study is to report a small-scale evaluative research project of a web-based technology with the educational potential to facilitate learning in relation to ethics, values, self-reflection and peer-based learning. Five diagnostic radiography students took part in a semi-structured focus group with the aim of exploring their experiences of using Values Exchange, an online ethical decision-making framework, to examine practice-based ethical issues. Transcripts were interrogated for key themes. From the thematic analysis three major themes emerged, understanding and appreciating others, addressing the theory-practice gap and delivering a safe and effective learning environment. Perceived limitations of the platform included students' fear of misinterpreted responses and possibility of poor group dynamics. There are varied approaches to how ethics and values are taught and assessed within health-related environments. Values Exchange is one such teaching tool and has been investigated and described positively by radiography students in this study. Online teaching tools can have a positive effect in helping students identify their own values but require skilled implementation to reap positive rewards. © 2018 The Authors.

    Implementation of the new European standards for industrial radiography with the use of storage phosphor imaging plates will result in the arousing of interest among numerous laboratories in non-destructive testing with application of the new method of testing to replace conventional radiography used so far, i.e. film radiography. Computer radiography is quite commonly used for medical radiography, where the fundamental problem consists in reduction of the radiation dose during the examination of a patient. However, it must be kept in mind that industrial applications have a little bit different requirements when compared with medical radiography. The article describes only new method for radiographic testing. (author)

    Aim: (1) Increase the nuclear pharmacy education opportunities across the United States and the around the world. (2) Establish collaborative educational agreements between colleges of pharmacy and local nuclear pharmacy preceptors. (3) Decrease the shortage of radio pharmacists. 4) Provide nuclear education courses to supplement existing educational programs. Materials and Methods: Nuclear Education Online (www.nuclearonline.org) is an educational consortium between the University of Arkansas for Medical Sciences and the University of New Mexico. The faculty members from each institution have collaborated to design an online didactic curriculum and experiential training materials. The didactic portion is delivered via WebCT (www.webct.com) and involves interactive studies with faculty from UNM and UAMS. The student-centered curriculum is based on the APhA Syllabus for Nuclear Pharmacy Training and includes interactive web-based course materials, discussion groups, preceptor-led activities and problem-based learning (PBL) case studies based upon actual clinical studies and real-life pharmacy situations. Individual units of study include Nuclear Physics, Radiation Biology, Radiation Safety, Instrumentation, and Radiochemistry/Radiopharmacology. Students can begin the program at anytime. Once a cohort of students is established, the students proceed through the PBL cases, working interactively as a group. Results: Since June 2001, over 26 students have completed the 10-week certificate program. These students have been located across the U.S. and in Saudi Arabia. Fifteen students have completed individual courses in nuclear physics and instrumentation through colleges of pharmacy course offerings using the NEO faculty as instructors. Student evaluations revealed that 78% of the students thought that the NEO program was a 'great way to learn' (highest rating). When comparing PBL to a traditional classroom setting, two thirds of students preferred problem

    To provide the high intensity neutron beam and support systems necessary for radiography, the Stationary Neutron Radiography System was constructed at McClellan Air Force Base. The Stationary Neutron Radiography System utilizes a one megawatt TRIGA reactor contained in an Aluminium tank surrounded by eight foot thick concrete walls. There are four neutron beam tubes at inclined angles from the reactor core to separate radiography bays. In three of the bays, robotic systems manipulate aircraft components in the neutron beam, while real-time imaging systems provide images concurrent with the irradiation. Film radiography of smaller components is performed in the remaining bay

    Neutron radiography is a radiographic method using a neutron beam of a defined geometry. The neutron source usually consists of a research reactor, a specialized neutron radiography reactor or the 252 Cf radioisotope source. There are two types of the neutron radiography display system, viz., a system producing neutron radiography images by a photographic process or a system allowing a visual display, eg., using a television monitor. The method can be used wherever X-ray radiography is used except applications in the radiography of humans. The neutron radiography unit at UJV uses the WWR-S reactor as the neutron source and both types of the above mentioned display system. (J.P.)

    Digital projection radiography may replace conventional radiography some day, provided it can meet several requirements: equal or better diagnostic effectiveness of the screen-film systems; reasonable image cost; real improvement in the productivity of the Departments of Imaging. All digital radiographic systems include an X-ray source, an image acquisition and formatting sub-system, a display and manipulation sub-system, and archiving subsystem and a laser editing system, preferably shared by other sources of digital images. Three digitization processes are available: digitization of the radiographic film, digital fluorography and phospholuminescent detectors with memory. The advantages of digital fluoroscopy are appealing: real-time image acquisition, suppression of cassettes; but its disadvantages are far from negligible: it cannot be applied to bedside radiography, the field of examination is limited, and the wide-field spatial resolution is poor. Phospholuminescent detectors with memory have great advantages: they can be used for bedside radiographs and on all the common radiographic systems; spatial resolution is satisfactory; its current disadvantages are considerable. These two systems, have common properties making up the entire philosophy of digital radiology and specific features that must guide our choice according to the application. Digital fluorography is best applied in pediatric radiology. However, evaluation works have showed that it was applicable with sufficient quality to many indications of general radiology in which a fluoroscopic control and fast acquisition of the images are essential; the time gained on the examination may be considerable, as well as the savings on film. Detectors with memory are required for bedside radiographs, in osteoarticular and thoracic radiology, in all cases of traumatic emergency and in the resuscitation and intensive care departments

    Full Text Available The use of Computers, Networks, and Internet has successfully enabled educational institutions to provide their students and instructors with various online educational services. With the recent developments in M-learning and mobile technology, further possibilities are emerging to provide such services through mobile devices such as mobile phones and PDAs. By providing the educational services using wireless and mobile technologies, the educational institutions can potentially bring great convenience to those off-campus students who do not always have time to find Internet enabled computers to get the important educational information from their academic institutions. With the mobile or M-educational services, both the students and the instructors can access the services anytime and anywhere they want. This paper discusses those M-educational services that can be moved to the mobile platform and then presents the system prototype and architecture that integrate these services into the mobile technology platform. The paper will conclude with a description of the formative evaluation of the system prototype.

    X-ray radiography is a very common technique used to check the homogeneity of a material or the inside of a mechanical part. Generally the radiation that goes through the material to check, produced an image on a sensitized film. This method requires time because the film needs to be developed, digital radiography has no longer this inconvenient. In digital radiography the film is replaced by digital data and can be processed as any computer file. This new technique is promising but its main inconvenient is that today its resolution is not so good as that of film radiography. (A.C.)

    2015-01-01

    Background: Radiography as a concept has mainly been associated with the functional role of the radiographer. The concept has been studied from a theoretical point of view. However, there is a lack of a theoretical foundation and research on the actual substance of the term radiography used in education. It is therefore important to undertake an investigation in order to determine how students after three years education understand the subject of radiography. Aim: The aim of this study was to analyse how students in the Swedish radiographers' degree program understand the concept of radiography. Method: A concept analysis was made according to the hybrid model, which combines theoretical, fieldwork and analytical phases. A summative content analysis was used to identify the number and content of statements. The empirical data were collected from questionnaires answered by radiography students at four universities in Sweden. Findings: All radiography students' exemplified radiography with statements related to the practical level although some of them also identified radiography at an abstract level, as a subject within a discipline. The attribute ‘An interdisciplinary area of knowledge’ emerged, which is an attribute on the abstract level. The practical level was described by four attributes: Mastering Medical Imaging’, ‘To accomplish images for diagnosis and interventions’, ‘Creating a caring environment’ and ‘Enabling fruitful encounters’. Conclusion: The hybrid model used was a versatile model of concept development. The results of this study have increased the understanding of what characterizes the concept of radiography in a Swedish context. - Highlights: • This concept analysis of radiography was undertaken according to a hybrid model. • In radiography humanistic aspects are emphasized, a shift from the technological perspective. • The attributes demonstrate the essence and interdisciplinary nature of radiography. • This

    2016-01-01

    Compassion is elemental in the care of a patient during their medical imaging (MI) procedure and is highly topical in the light of the Francis Report. The patient–practitioner interaction is an amalgam of context, communication and individual differences, and whilst compassion is a term in common parlance in the media, policy and radiographers' professional documents, its meaning and manifestation in radiography recruitment, education and practice are less clearly articulated. A review of the existing literature was undertaken, including a small scale study exploring patients' experiences in diagnostic medical imaging. Themes from the study included communication; competence; emotions; attitudes and relationships, but notably absent was any mention of compassion per se. Radiography research would benefit from further exploratory work into the nature of compassionate patient care in the unique context of the medical imaging encounter; offering an evidence-based contribution to radiography in the light of the Francis Report. - Highlights: • An increased focus on compassion was recommended in the Francis Report. • Best compassionate care is a requirement in radiographers' Code of Professional Conduct. • The meaning of compassionate patient care in radiography is not well understood. • Equally neither is the expression of compassion in radiography. • Research into compassion will contribute to evidence-based practice in radiography.

    Perioperative nurses must use critical thinking and sound clinical judgment to meet their patients' needs safely and effectively. This requires the integration and continual updating of large amounts of detailed clinical information. Innovative education strategies are designed to make teaching and learning more interesting and interactive, especially for the presentation of complex subject material. One interactive educational strategy is the use of games. Educational games can foster collaboration and critical thinking among peers and associates. An example of this was the Perioperative QuizBowl: Evidence-Based Practice presented at the annual AORN Congress from 2003 to 2010, which was used to teach and reinforce evidence-based practice in a fun, competitive way. Although AORN no longer presents this offering, the QuizBowl format demonstrates how educational games can support clinical practice. Copyright © 2011 AORN, Inc. Published by Elsevier Inc.

Gifted education programs vary both among and within countries and who is served in these programs depends largely on the definitions used. The topics explored in this issue include perceptions and policies of gifted education in cultures and countries across the globe; the presumed dichotomy of equity and excellence in countries as different in ideologies as the United States and China; underrepresentation of culturally diverse students, a problem that has plagued the field for decades; gifted education in rural communities; and using a virtual environment for students to pose and share mathematical problems.

    The Coulomb multiple scattering of charged particles as they pass through material allows them to be used as a radiographic probe. This forms the basis for a new kind of radiography that is finding application where conventional x-ray radiography is limited by flux or backgrounds. Charged-particle radiography is providing a versatile new probe that has advantages over conventional x-ray radiography for some unique application. Proton radiography has been used to make quantitative motion pictures of high explosive driven experiments and proves to be of great value for radiographing experiments that mock up nuclear weapon primaries for stockpile certification. By taking advantage of magnetic lens to magnify images and by using the very bright beams that can be made with electrons, charged-particle radiography may be useful for studying the fine spatial detail and very fast motion in laser driven implosion experiments at the National Ignition Facility. Finally, radiographs can be made using cosmic-ray muons for searching vehicles and cargo containers for surreptitious cargo of high z materials such as uranium or plutonium.

    International Nuclear Information System (INIS)

    Hendry, Julie Anne

    2013-01-01

    This review article aims to explore the concept of radiography lecturers acting as leaders to their student followers. Through a brief review of the literature, a definition of leadership is suggested and some leadership theories explored. The path-goal theory, leader–member exchange theory and the contemporary theory of transformational leadership are examined more closely. Links between lecturer-leader behaviour and student motivation and learning are tentatively suggested with transformational leadership appearing to offer the optimal leadership style for lecturers to adopt. The paucity of literature relating directly to radiography is acknowledged and areas for further research are suggested. The article concludes with some of the author's practical ideas for incorporating transformational leadership styles and behaviours into radiography education today

    Industrial radiography is a non-destructive testing (NDT) method which allows components to be examined for flaws without interfering with their usefulness. It is one of a number of inspection methods which are commonly used in industry to control the quality of manufactured products and to monitor their performance in service. Because of its involvement in organizing training courses in all the common NDT methods in regional projects in Asia and the Pacific and Latin America and the Caribbean and in many country programmes, the Agency is aware of the importance of standardizing as far as possible the syllabi and training course notes used by the many experts who are involved in presenting the training courses. IAEA-TECDOC-628 ''Training Guidelines in Non-destructive Testing'' presents syllabi which were developed by an Agency executed UNDP project in Latin America and the Caribbean taking into account the developmental work done by the International Committee for Non-destructive Testing. Experience gained from using the radiography syllabi from TECDOC-628 at national and regional radiography training courses in the Agency executed UNDP project in Asia and the Pacific (RAS/86/073) showed that some guidance needed to be given to radiography experts engaged in teaching at these courses on the material which should be covered. The IAEA/UNDP Asia and Pacific Project National NDT Coordinators therefore undertook to prepare Radiography Training Course Notes which could be used by experts to prepare lectures for Level 1,2 and 3 radiography personnel. The notes have been expanded to cover most topics in a more complete manner than that possible at a Level 1, 2 or 3 training course and can now be used as source material for NDT personnel interested in expanding their knowledge of radiography.

    Dental radiography must comply with the same regulations with which conventional radiography complies. Radiation doses to individual patients are low but, because of the large number of patients X-rayed, the collective dose to the population is not negligible. Care in siting and regular maintenance of the equipment will reduce doses to both staff and patients. To produce X-ray films with a good image quality using a low radiation dose requires attention to film processing; this is often a neglected area. (Author)

    Computed radiography has also been called storage phosphor technology, digital luminescence radiography and scintillation phosphor technology, since it relies on phosphor imaging plate as an alternative to screen-film. One of the major advantages in the use of computed radiography (CR) is the consistent image quality independence of the radiographer and exposure used. And secondly a marked reduction in the need for repeat films was achieved and thus a decrease in dose to the patient. In some cases, dose was able to be reduced further due to the fact that the plates respond to lower doses and still provide adequate image quality. Digitalising the Cr image allows it to be transmitted to an imaging console. The images can then be stored on optical disc. 7 refs

    The digital processing of the neutron radiography images gives the possibility for data quantification. In this case an exact relation between the measured neutron attenuation and the real macroscopic attenuation coefficient for every point of the sample is required. The assumption that the attenuation of the neutron beam through the sample is exponential is valid only in an ideal case where a monochromatic beam, non scattering sample and non background contribution are assumed. In the real case these conditions are not fulfilled and in dependence on the sample material we have more or less deviation from the exponential attenuation law. Because of the high scattering cross-sections of hydrogen (σs=80.26 barn) for thermal neutrons, the problem with the scattered neutrons at quantitative radiography investigations of hydrogenous materials (as PE, Oil, H 2 O, etc) is not trivial. For these strong scattering materials the neutron beam attenuation is no longer exponential and a dependence of the macroscopic attenuation coefficient on the material thickness and on the distance between the sample and the detector appears. When quantitative radiography (2 D) or tomography investigations (3 D) are performed, some image correction procedures for a description of the scattering effect are required. This thesis presents a method that can be used to enhance the neutron radiography image for objects with high scattering materials like hydrogen, carbon and other light materials. This method uses the Monte Carlo code, MCNP5, to simulate the neutron radiography process and get the flux distribution for each pixel of the image and determine the scattered neutrons distribution that causes the image blur and then subtract it from the initial image to improve its quality.

    Because of its practical aspect digital radiography is more and more used in the industrial sector. There are 2 kinds of digital radiography. First, the 'computed radiography' that uses a photon-stimulated screen, and after radiation exposure this screen must be read by an analyser to get a digit image. The second type is the 'direct radiography' that allows one to get a digit radiograph of the object directly. Digital radiography uses the same radioactive nuclides as radiography with silver films: cobalt, iridium or selenium. The spatial resolution of digital radiography is less good than with classical silver film radiography but digital radiography offers a better visual contrast. (A.C.)

    Free open access to medical education (FOAM, #FOAM) is the free availability of educational materials on various medicine topics. We hope to evaluate the use of social media and FOAM by emergency medical services (EMS) providers. We designed an online survey distributed to EMS providers with questions about demographics and social media/FOAM use by providers. The survey was sent to the American College of Emergency Physicians (ACEP) EMS Listserv of medical directors and was asked to be distributed to their respective agencies. The survey was designed to inquire about the providers' knowledge of FOAM and social media and their use of the above for EMS education. There were 169 respondents out of a total of 523 providers yielding a response rate of 32.3%. Fifty-three percent of respondents are paramedics, 37% are EMT-Basic trained, and the remainder (16%) were "other." The minority (20%) of respondents had heard of FOAM. However, 54% of respondents had heard of "free medical education online" regarding pertinent topics. Of the total respondents who used social media for education, 31% used Facebook and 23% used blogs and podcasts as resources for online education. Only 4% of respondents stated they produced FOAM content. Seventy-six percent of respondents said they were "interested" or "very interested" in using FOAM for medical education. If FOAM provided continuing medical education (CME), 83% of respondents would be interested in using it. Social media is not used frequently by EMS providers for the purposes of FOAM. There is interest within EMS providers to use FOAM for education, even if CME was not provided. FOAM can provide a novel area of education for EMS.

    Digital Radiography begins with an orderly introduction to the fundamental concepts of digital imaging. The entire X-ray digital imagining system is described, from an overall characterization of image quality to specific components required for a digital radiographic system. Because subtraction is central to digital radiographic systems, the author details the use of various subtraction methods for image enhancement. Complex concepts are illustrated with numerous examples and presented in terms that can readily be understood by physicians without an advanced mathematics background. The second part of the book discusses implementations and applications of digital imagining systems based on area and scanned detector technologies. This section includes thorough coverage of digital fluoroscopy, scanned projection radiography, and film-based digital imaging systems, and features a state-of-the-art synopsis of the applications of digital subtraction angiography. The book concludes with a timely assessment of anticipated technological advances

    Background: Practice education is a compulsory component of health programs with practice educators playing a critical role in the education of students. Practice educator characteristics may positively or negatively affect student learning in practice settings. This study aimed to identify characteristics of the ideal practice educator that lead to successful practical experiences as perceived by current practice educators working in the Australian context of diagnostic radiography, nuclear medicine, nutrition and dietetics, occupational therapy, physiotherapy and radiation therapy. Methods: All practice educators (n = 1063) on the University of Newcastle Practice Educator Database were invited to participate in this prospective, cross-sectional, descriptive study via online link or paper format. Results: There was a 52% response rate. The five most valued characteristics were feedback skills, non-judgemental, professionalism, clarity and listening skills. The five least valued characteristics were scholarly activity, respect for students' autonomy, well-prepared, availability and being a role model. Comparisons between disciplines, genders, ages, years in practice and levels of supervisory experience indicated some statistically significant differences, though actual differences were small. Discussion: Overall there was a high degree of agreement within and between disciplines on the characteristics of the ideal practice educator. The top five skills could be classed as generic skills and not specific clinical and practice skills, thus formal training and certification schemes may enhance practice educator competence. - Highlights: • The most important characteristics were feedback skills and non-judgmental. • The least important characteristics were scholarly activity and respects student autonomy. • Female educators valued all characteristics except scholarly activities as being more important. • Older participants valued availability, and

    In the present paper a new radiography technique, the 'Neutron Induced Electron Radiography' - NIER, to inspect low thickness samples on the order of micra, has been developed. This technique makes use of low energy electrons as penetrating radiation generated from metallic gadolinium screens when irradiated by thermal neutrons. The conditions to obtain the best image for the conventional X-ray film Kodak-AA were determined by using a digital system to quantify the darkening level of the film. The irradiations have been performed at a radiography equipment installed at the beam-hole no. 8 of the 5 MW IEA-R1 nuclear research reactor of IPEN-CNEN/SP. The irradiation time to obtain the best radiography was 100 seconds and for such condition the technique was able to discern 1 μm in 24 μm of aluminum at a resolution of 32 μm. By visual comparison the images obtained by the NIER shown a higher quality when compared with the ones from other usual techniques the make use of electrons a penetrating radiation and films for image registration. Furthermore the use of the digital system has provided a smaller time for data acquisition and data analysis as well as an improvement in the image visualization. (author)

    Background Electronic consultation systems allow primary care providers to receive timely speciality expertise via iterative electronic communication. The use of such systems is expanding across the USA with well-documented high levels of user satisfaction. We characterise the educational impact for primary care providers of a long-standing integrated electronic consultation and referral system. Methods Primary care providers' perceptions of the educational value inherent to electronic consultation system communication and the impact on their ability to manage common speciality clinical conditions and questions were examined by electronic survey using five-point Likert scales. Differences in primary care providers' perceptions were examined overall and by primary care providers' speciality, provider type and years of experience. Results Among 221 primary care provider participants (35% response rate), 83.9% agreed or strongly agreed that the integrated electronic consultation and referral system provided educational value. There were no significant differences in educational value reported by provider type (attending physician, mid-level provider, or trainee physician), primary care providers' speciality, or years of experience. Perceived benefit of the electronic consultation and referral system in clinical management appeared stronger for laboratory-based conditions (i.e. subclinical hypothyroidism) than more diffuse conditions (i.e. abdominal pain). Nurse practitioners/physician assistants and trainee physicians were more likely to report improved abilities to manage specific clinical conditions when using the electronic consultation and/or referral system than were attending physicians, as were primary care providers with ≤10 years experience, versus those with >20 years of experience. Conclusions Primary care providers report overwhelmingly positive perceptions of the educational value of an integrated electronic consultation and referral system. Nurse

    Although pediatric-specific objectives for the initial education of prehospital providers have been established, uniform implementation of these objectives and guidelines for hours of required pediatric continuing education (CE) for prehospital providers have not been established. To examine the content and number of hours of pediatric-specific education that prehospital providers receive during initial certification and recertification. Second, to identify barriers to implementing specific requirements for pediatric education of prehospital providers. Electronic surveys were sent to 55 EMS for Children (EMSC) State Partnership grantee program managers inquiring about the certification and recertification processes of prehospital providers and barriers to receiving pediatric training in each jurisdiction. We had a 91% response rate for our survey. Specified pediatric education hours exist in more states and territories for recertification (63-67%) than initial certification (41%). Limitations in funding, time, instructors, and accessibility are barriers to enhancing pediatric education. Modifying statewide policies on prehospital education and increasing hands-on training may overcome identified barriers.

    The technology of radiography is developing rapidly, both regarding imaging technology and data hardware, and software technology. More and more advanced systems are marketed by the radiological companies. The wide product range makes it difficult to get an overview over principles and components. By closer inspection, however, the number of basic components and technologies is limited. Moreover, the components seem rather well known from other technologies, due to the long times of development in radiology. This report gives a survey of some new principles and components in the video chain. As components may deteriorate or age fast by irradiation, the radiation levels in the chain are evaluated. 13 refs

    A well-organized educational curriculum for the training of both novice and experienced ECMO providers is critical for the continued function of an institutional ECMO program. ELSO provides guidance for the education for ECMO specialists, physicians and staff, which incorporates "traditional" instructor-centered educational methods, such as didactic lectures and technical skill training. Novel research suggests utilization of strategies that align with principles of adult learning to promote active learner involvement and reflection on how the material can be applied to understand existing and new constructs may be more effective. Some examples include the "flipped classroom," e-learning, simulation, and interprofessional education. These methodologies have been shown to improve active participation, which can be related to improvements in understanding and long-term retention. A novel framework for ECMO training is considered. Challenges in assessment and credentialing are also discussed. Copyright © 2018 Elsevier Inc. All rights reserved.

    2016-03-01

    Spiritual care is a critical part of holistic care, and nurses require adequate preparation to address the spiritual needs of patients. However, nurses' willingness to provide such care has rarely been reported. Hence, nurses' education, and knowledge of spiritual care, as well as their willingness to provide it require further study. A convenience sample of 200 nurses participated in the study. Quantitative data were collected using a 21-item Spiritual Care Needs Inventory (content validity index=.87; Cronbach's alpha=.96). The majority of participants were female (96.5%, n=193) between 21 and 59years old (mean=35.1years). Moreover, the majority of participants had a Bachelor's degree (74.0%, n=148) and 1-36years of clinical experience (mean=12.13years). Regarding religious beliefs, 63 (31.5%) had no religious belief, and 93 (46.5%) did not engage in any religious activity. Overall, the nurses were willing to provide spiritual care, although only 25 (12.5%) felt that they had received adequate education. The findings of this study indicate the need for further educational preparation in spiritual care for nurses. Specifically, additional teaching materials are required that are more directly related to spiritual care. Greater emphasis should be placed on different subject areas in school-based education, continuing education, and self-learning education according to the needs of nurses. Since spiritual care education needs policy support, in-depth discussions should take place regarding the approach and cultural environment for providing spiritual care in future nursing courses. Moreover, further studies should investigate barriers in providing spiritual nursing care to patients and whether they are the results of a lack of relevant knowledge or other factors.

    Neutron radiography (or radiology) is a diverse filed that uses neutrons of various energies, subthermal, thermal, epithermal or fast in either steady state or pulsed mode to examine objects for industrial, medical, or other purposes, both microscopic and macroscopic. The applications include engineering design, biological studies, nondestructive inspection and materials evaluation. In the past decade, over 100 different centers in some 30 countries have published reports of pioneering activities using reactors, accelerators and isotopic neutron sources. While film transparency and electronic video are most common imaging methods for static or in motion objects respectively, there are other important data gathering techniques, including track etch, digital gauging and computed tomography. A survey of the world-wide progress shows the field to be gaining steadily in its diversity, its sophistication and its importance. (author)

Diffuser means receive a beam of electrons and diffuse the electrons before they enter first matching quadrupoles where the diffused electrons are focused prior to the diffused electrons entering an object. First imaging quadrupoles receive the focused diffused electrons after the focused diffused electrons have been scattered by the object for focusing the scattered electrons. Collimator means receive the scattered electrons and remove scattered electrons that have scattered to large angles. Second imaging quadrupoles receive the collimated scattered electrons and refocus the collimated scattered electrons and map the focused collimated scattered electrons to transverse locations on an image plane representative of the electrons' positions in the object.

    1997-01-01

    Technology initially prototyped under a Small Business Innovation Research contract between Quantex Corporation and Langley Research Center was licensed to Liberty Technology and incorporated into RADView, a new filmless radiography technology. The NASA-sponsored work involved the investigation of Electron Trapping, which led to a solid-state film that uses a special class of photoluminescent materials to capture radiographic images. RadView is a total imaging solution for the conversion of radiographic film records to digital format and digital acquisitions of radiographs. With the RADView technology, there is a reduction of exposure times and errors; film waste is eliminated; and the efficiency of data management and precise image analysis is boosted. The solid-state film can be exposed, read, erased, and re- exposed indefinitely until mechanical replacement is required. Digital images can be stored to optical media for up to 100 years and beyond without information loss.

    Heavy-particle radiography has clinical potential as a newly developed noninvasive low-dose imaging procedure that provides increased resolution of minute density differences in soft tissues of the body. The method utilizes accelerated high-energy ions, primarily carbon and neon, at the Bevalac accelerator at the Lawrence Berkeley Laboratory. The research program for medicine utilizes heavy-ion radiography for low-dose mammography, for treatment planning for cancer patients, and for imaging and accurate densitometry of skeletal structures, brain and spinal neoplasms, and the heart. The potential of heavy-ion imaging, and particularly reconstruction tomography, is now proving to be an adjunct to existing diagnostic imaging procedures in medicine, both for applications to the diagnosis, management and treatment of clinical cancer in man, and for the early detection of small soft-tissue tumors at low radiation dose

    2002-06-01

    With the permanent habitation of the International Space Station, the planning of longer duration exploration missions, and the possibility of space tourism, it is likely that digital radiography will be needed in the future to support medical care in space. Ultrasound is currently the medical imaging modality of choice for spaceflight. Digital radiography in space is limited because of prohibitive launch costs (in the region of $20,000/kg) that severely restrict the volume, weight, and power requirements of medical care hardware. Technological increases in radiography, a predicted ten-fold decrease in future launch costs, and an increasing clinical need for definitive medical care in space will drive efforts to expand the ability to provide medical care in space including diagnostic imaging. Normal physiological responses to microgravity, in conjunction with the high-risk environment of spaceflight, increase the risk of injury and could imply an extended recovery period for common injuries. The advantages of gravity on Earth, such as the stabilization of patients undergoing radiography and the drainage of fluids, which provide radiographic contrast, are unavailable in space. This creates significant difficulties in patient immobilization and radiographic positioning. Gravity-dependent radiological signs, such as lipohemarthrosis in knee and shoulder trauma, air or fluid levels in pneumoperitoneum, pleural effusion, or bowel obstruction, and the apical pleural edge in pneumothorax become unavailable. Impaired healing processes such as delayed callus formation following fracture will have implications on imaging, and recovery time lines are unknown. The confined nature of spacecraft and the economic impossibility of launching lead-based personal protective equipment present significant challenges to crew radiation safety. A modified, free-floating radiographic C-arm device equipped with a digital detector and utilizing teleradiology support is proposed as a

    The aim of this study was to evaluate the contamination rate of intra and extraoral digital X ray equipment in a dental radiology clinic at a public educational institution. Samples were collected on three different days, at two times in the day: in the morning, before attending patients, and at the end of the day, after appointment hours and before cleaning and disinfection procedures. Samples were collected from the periapical X-ray machine (tube head, positioning device, control panel and activator button), the panoramic X- ray machine (temporal support, bite block, control panel and activator button), the intraoral digital system (sensor), and the digital system computers (keyboard and mouse). The samples were seeded in different culture media, incubated, and colony forming units (CFU/mL) counted. Biochemical tests were performed for suspected colonies of Staphylococcus, Streptococcus and Gramnegative bacilli (GNB). Fungi were visually differentiated into filamentous fungi and yeasts. The results indicated the growth of fungi and Staphylococcus fromall sampling locations. GNB growth was observed from all sites sampled from the intraoral X-ray equipment. On the panoramic unit, GNB growth was observed in samples from activator button, keyboard and mouse. In general, a higher number of CFU/mL was present before use. It can be concluded that more stringent protocols are needed to control infection and prevent X-ray exams from acting as vehicle for cross contamination.

    For the first topic in this book, more on introduction to nondestructive testing, also a little bit on another technique such as magnetic testing, liquid penetrated, ultrasonic testing and others. This book mentions more on radiographic testing and for that, more details on this topic such as history, definition and devices that use in this technique. This radiography testing firstly started with the discovering of x-ray by Wilhelm Roentgen (1895). So, on 1913, David Coolidge successfully invented and developed x-ray tube that could made x-ray more intensified and produced highly penetration forces. Radiography in Malaysia firstly started two years after the discovery made by Wilhelm Roentgen when one hospital here used the x-ray machine for medical purposes. Besides using x-ray, radiography also used gamma rays, and for these purpose, they used Co-60 and Ir-192. Now, more company based on NDT established to provide a service on inspection pipe and others. For filled these requirement, radiographer must take an exam to make them expert and trained well to work in this field. There is no advantage using this technique or other technique. So that's why this book was published to make people understand what is radiographic testing truly.

    In considering the special provisions required in dental radiography, investigations were conducted in Iran. Radiation dose levels in dental radiography were found to be high. Patient exposure from intraoral radiographic examination was calculated, using 50kV X-ray. Thermoluminescent dosimeters were fastened to the nasion, eyes, lip, philtrum, thyroid, gonads and to the right and left of the supra-orbital, infra-orbital temporomandibular joints of live patients. The highest exposure value was for the lower lip. Recommendations concerning educational training and protection of staff and patients were included

    Most students diagnosed with disabilities in Thai special education schools received assistive technologies, but this did not guarantee the greatest benefits. The purpose of this study was to survey the provision, use and needs of assistive technologies, as well as the perspectives of key informants regarding a model of providing them in special education schools. The participants were selected by the purposive sampling method, and they comprised 120 students with visual, physical, hearing or intellectual disabilities from four special education schools in Chiang Mai, Thailand; and 24 key informants such as parents or caregivers, teachers, school principals and school therapists. The instruments consisted of an assistive technology checklist and a semi-structured interview. Results showed that a category of assistive technologies was provided for students with disabilities, with the highest being "services", followed by "media" and then "facilities". Furthermore, mostly students with physical disabilities were provided with assistive technologies, but those with visual disabilities needed it more. Finally, the model of providing assistive technologies was composed of 5 components: Collaboration; Holistic perspective; Independent management of schools; Learning systems and a production manual for users; and Development of an assistive technology center, driven by 3 major sources such as Government and Private organizations, and Schools.

    2005-01-01

    The Radiation Protection group wishes to remind CERN staff responsible for contractors performing X-ray inspections on the CERN sites that the firms must apply the legislation in force in their country of origin, in particular with regard to the prevention of risks relating to ionizing radiation. Industrial radiography firms called on to work on the CERN sites must also comply with the rules laid down in CERN's Radiation Safety Manual and be registered in the relevant CERN database. Since CERN is responsible for safety on its own site, a number of additional rules have been laid down for this kind of work, as set out in Radiation Protection Procedure PRP30 https://edms.cern.ch/file/346848/LAST_RELEASED/PRP30.pdf The CERN Staff Member responsible for the contract shall register the company and issue notification that an X-ray inspection is to be performed via the web interface at the following address: http://cern.ch/rp-radio

    The thermal neutron absorption coefficient is essentially different from the X-ray absorption coefficient. Each substance has a characteristic absorption coefficient regardless of its density. Neutron deams have the following features: (1) neutrons are not transmitted efficiently by low molecular weight substances, (2) they are transmitted efficiently by heavy metals, and (3) the transmittance differs among isotopes. Thus, neutron beams are suitable for cheking for foreign matters in heavy metals and testing of composites consisting of both heavy and light materials. A neutron source generates fast neutrons, which should be converted into thermal neutrons by reducing their energy. Major neutron souces include nuclear reactors, radioisotopes and particle accelerators. Photographic films and television systems are mainly used to observe neutron transmission images. Computers are employed for image processing, computerized tomography and three-dimensional analysis. The major applications of neutron radiography include inspection of neclear fuel; evaluation of material for airplane; observation of fuel in the engine and oil in the hydraulic systems in airplanes; testing of composite materials; etc. (Nogami, K.)

    Bires, Angela Macci; Leonard, Amanda L; Thurber, Brandon

    As the awareness of concussions increases, it is imperative to be able to evaluate, diagnose, and treat concussed individuals properly to prevent further complications or death. The primary purpose of this study was to compare a provider's current awareness and comfort level as it relates to the return-to-play guidelines for concussions. A secondary aim was to evaluate current protocols that are in use and determine whether they coincide with the suggested guidelines. An educational intervention was implemented to assess the knowledge and confidence of health care providers. The study design was a quantitative, convenient sample, pretest/posttest questionnaire. The questionnaire was administered to participants who were nurse practitioners prior to an educational PowerPoint presentation. At 8 weeks, the posttest was administered. Approximately 19% of individuals were not aware of a graded return-to-play protocols. The findings suggest that the educational intervention increased their confidence levels in making a diagnosis of a concussion, in assessing danger signs, and in understanding when to refer to a specialist. Additional supporting evidence from this study indicates that the educational intervention allowed the participants to achieve a greater comfort level in finding appropriate resources for them and their patients.

    The techniques of radiography of the chest in all pediatric-age groups differ only slightly from those used in adult radiography. The technologist's principal challenge, however, relates to optimum handling of the patient with respect to positioning and radiation protection. The hints provided in this chapter should permit the conscientious radiographer to obtain high quality radiographs on all pediatric patients

  3. Portable digital electronic radiography system

    Radiography is a standard nondestructive technique in the industrial testing of materials and components. It is routinely used during the construction, maintenance and repair of nuclear plants. Traditionally, radiography is performed using photographic film (film radiography, FR). Recent developments in solid-state area imaging radiation detectors, miniature electronics and computer software/hardware techniques have brought electronic alternatives to FR. In recent years various electronic radiography (ER) techniques have served as alternatives to FR, these proved beneficial in some applications. While originally developed to provide real time imaging, ER may offer other advantages over FR, depending on the application. Work was undertaken at CRL to review progress in ER techniques and evaluate the possibility of constructing a portable DER (digital electronic radiography) system, for the inspection of power plant components. A suitable DER technique has been developed and a proof of principle portable system constructed. As this paper demonstrates, a properly designed ER system can be small and compact, while providing radiographic examination with acceptable image quality and the benefits of ER imaging. The CRL DER system can operate with radioactive sources typical of FR. While it does not replace FR, our DER system is expected to be beneficial in specific applications for Candu maintenance, reducing cost, labour and time. Practical, cost saving applications of this system are expected to include valve monitoring and foreign object location during maintenance at Candu reactors

  4. Healthcare provider education: from institutional boxes to dynamic networks.

    2009-01-01

    The world recognizes the need for close collaboration in planning between the healthcare system and the post-secondary education system; this has also been advocated in the lead article. Forums and mechanisms to facilitate this collaboration are being implemented from local to global environments. Beyond the focus on competency gaps, there are important functional co-dependencies between healthcare and post-secondary education, including the need for a more formalized continuous quality improvement approach at the inter-organizational system level. The case for this close and continuous collaborative relationship is based on the following: (1) a close functional relationship, (2) joint responsibility for healthcare provider education, (3) the urgent need to address the workforce and education strategies for almost all healthcare services areas and (4) the factors that characterize successful and sustained quality improvement in complex adaptive systems. A go-forward vision consisting of an integrated web of academic health networks is proposed, each with its particular shared vision and aligned with an overall vision for healthcare in each provincial jurisdiction, as well as with national and global healthcare objectives.

    Role of accreditation authorities: If accreditation authorities are to provide leadership in medical education they must undertake regular review of their standards. This should be informed by all stakeholders and include experts in medical education. The format of the standards must provide clear direction to medical schools. Accreditation should take place regularly and should result in the production of a publicly accessible report.

  9. Neutron radiography for nondestructive testing

    International Nuclear Information System (INIS)

    John, J.

    1979-01-01

    Neutron radiography is similar to X-ray inspection in that both depend upon use of radiation that penetrates some materials and is absorbed by others to provide a contrast image of conditions not readily available for visual inspection. X-rays are absorbed by dense materials, such as metals, whereas neutrons readily penetrate metals, but are absorbed by materials containing hydrogen. The neutron radiography has been successfully applied to a number of inspection situations. These include the inspection of explosives, advanced composites, adhesively bonded structures and a number of aircraft engine components. With the availability of Californium-252, it has become feasible to construct mobile neutron radiography systems suitable for field use. Such systems have been used for in-situ inspection of flight line aircraft, particularly to locate and measure hidden corrosion

    The TREAT reactor was built as a transient irradiation test reactor. By taking advantage of built-in system features, it was possible to add a neutron-radiography facility. This facility has been used over the years to radiograph a wide variety and large number of preirradiated fuel pins in many different configurations. Eight different specimen handling casks weighing up to 54.4 t (60 T) can be accommodated. Thermal, epithermal, and track-etch radiographs have been taken. Neutron-radiography service can be provided for specimens from other reactor facilities, and the capacity for storing preirradiated specimens also exists

    2012-01-01

    Objective Otolaryngic disorders are very common in primary care, comprising 20–50% of presenting complaints to a primary care provider. There is limited otolaryngology training in undergraduate and postgraduate medical education for primary care. Continuing medical education may be the next opportunity to train our primary care providers (PCPs). The objective of this study was to assess the otolaryngology knowledge of a group of PCPs attending an otolaryngology update course. Methods PCPs enrolled in an otolaryngology update course completed a web-based anonymous survey on demographics and a pre-course knowledge test. This test was composed of 12 multiple choice questions with five options each. At the end of the course, they were asked to evaluate the usefulness of the course for their clinical practice. Results Thirty seven (74%) PCPs completed the survey. Mean knowledge test score out of a maximum score of 12 was 4.0±1.7 (33.3±14.0%). Sorted by area of specialty, the mean scores out of a maximum score of 12 were: family medicine 4.6±2.1 (38.3±17.3%), pediatric medicine 4.2±0.8 (35.0±7.0%), other (e.g., dentistry, emergency medicine) 4.2±2.0 (34.6±17.0%), and adult medicine 3.9±2.1 (32.3±17.5%). Ninety one percent of respondents would attend the course again. Conclusion There is a low level of otolaryngology knowledge among PCPs attending an otolaryngology update course. There is a need for otolaryngology education among PCPs. PMID:22754276

    Phillips, N.M.

    1994-07-01

    This Process Waste Assessment was conducted to evaluate the Radiography Laboratory, located in Building 923. It documents the processes, identifies the hazardous chemical waste streams generated by these processes, recommends possible ways to minimize waste, and serves as a reference for future assessments of this facility. The Radiography Laboratory provides film radiography or radioscopy (electronic imaging) of weapon and nonweapon components. The Radiography Laboratory has six x-ray machines and one gamma ray source. It also has several other sealed beta- and gamma-ray isotope sources of low microcurie (μCi) activity. The photochemical processes generate most of the Radiography Laboratory's routinely generated hazardous waste, and most of that is generated by the DuPont film processor. Because the DuPont film processor generates the most photochemical waste, it was selected for an estimated material balance

    Objective: To evaluate the quality and usefulness of direct digital radiography system in roentgenogram of chest in clinical practice. Methods: 1000 cases of chest roentgenograms with digital radiography and high kV conventional radiography were selected for analysis by 3 senior radiologists. Results: 1. With digital radiography system, the quality of chest film was assessed as grade A in 50.6%, grade B in 38.5%, grade C in 10.9%, and no waste film. 2. With conventional high kV radiography, the quality of chest film was assessed as grade A in 41.1%, grade B in 44.1%, grade C in 13.3%, and waste film in 1.5%. The direct digital radiography was statistically superior to the conventional high kV radiography. 3. The fine structure of the lungs could be revealed in 100.0% of chest roentgenogram with direct digital radiograph system, which was significantly higher than that acquired with the conventional high KV radiography (78.6%, P < 0.001). Conclusion: Direct digital radiography could provide the chest film with better quality than that with the conventional high kV radiography. The direct digital radiography system is easy to operate, fast in capturing imaging and could provide post-processing techniques, which will facilitate the accurate diagnosis of chest radiography

  16. Interprofessional working in diagnostic radiography

    International Nuclear Information System (INIS)

    Strudwick, Ruth M.; Day, Jane

    2014-01-01

    This paper considers interprofessional working within one diagnostic imaging department. The literature is still divided about the long-term impact of interprofessional learning in pre-registration health and social care education, and its impact on the quality of care provided. When reading the literature about interprofessional working the main topics considered by other authors are team working, communication between professionals, stereotyping and tribalism. The results presented are from an ethnographic study in one department with participant observation and semi-structured interviews. The three main aspects discussed in this paper are; tribalism and culture within the diagnostic radiography profession, communication between different professional groups, and a lack of understanding of the roles of other professional groups. It was evident from the results of this study that tribalism and culture, and a lack of understanding were significant barriers to interprofessional working. It was felt by the authors that pre-registration and post-registration interprofessional education could be significant in changing the culture of the NHS in the future as more professionals learn from and about one another

    Presacco, D.; Pellegrini, A.; Di Maggio, C.

    1987-01-01

    The value of direct magnification radiography of the hand and the wrist has been studied in 128 patients affected by rheumatic diseases. Only in a small group (3.17%) magnification determined a higher percentage of correct diagnosis; in the 17.06% of cases direct magnification radiography provided useful increase in information but did not change the diagnisis correctly reached by conventional techniques. In most cases (79.76%) magnification provided only a better image quality but no more information helpful for the diagnosis, because of the high level achieved by convetional techniques. Therefore direct magnification radiography must be used only in selected cases and not as routine radiographyc technique

    Hafslund, Bjorg; Clare, Judith; Graverholt, Birgitte; Wammen Nortvedt, Monica

    2008-01-01

    Evidence-based practice (EBP) offers the integration of the best research evidence with clinical knowledge and expertise and patient values. EBP is a well known term in health care. This paper discusses the implementation of EBP into radiography and introduces the term evidence-based radiography. Evidence-based radiography is radiography informed and based on the combination of clinical expertise and the best available research-based evidence, patient preferences and resources available. In Norway, EBP in radiography is being debated and radiographers are discussing the challenges of implementing EBP in both academic and clinical practice. This discussion paper explains why EBP needs to be a basis for a radiography curriculum and a part of radiographers' practice. We argue that Norwegian radiographers must increase participation in research and developing practice within their specific radiographic domain

  20. The changing concept of competence and categorisation of learning outcomes in Europe: Implications for the design of higher education radiography curricula at the European level

    International Nuclear Information System (INIS)

    Castillo, Joseph; Caruana, Carmel J.; Wainwright, David

    2011-01-01

    The Bologna process has made the qualifications framework of the European Higher Educational Area based on three cycles and on learning outcomes central to curriculum development in higher education in Europe. The Tuning Educational Structures in Europe project recommended that learning outcomes be expressed in terms of competences. The expression of educational programme learning outcomes as inventories of competences has since become the norm at the European level. However, the more recent European Qualifications Framework for lifelong learning utilises a tripartite set of categories of learning outcomes, namely, knowledge, skills and competence. In addition, the definition of competence used though overlapping with that used by Tuning, is however not identical. This article reviews and discusses the changing definition of the concept of competence and changes in categorisation of learning outcomes in Europe and their potential impact on curriculum development in radiography at the European level. It is proposed that the shift in the definition of competence and in the categorisation of learning outcomes should be taken into account in the formulation of new European curricula or the updating of present ones so that they may reference in a more direct manner to the levels of the European Qualifications Framework.

    Beside radiography testing using x-ray machine and gamma source, there are several technique that developed specifically to complete the testing that cannot be done with the two earlier. This technique was specific based on several factor, for the example, the advantages of neutron and electron using to show the image was unique compare to x-ray and gamma. Besides that, these special radiography techniques maybe differ in how to detect the radiation get through the object. These technique can used to inspect thin or specimen that contained radioactive material. There are several technique will discussed in this chapter such as neutron radiography, electron radiography, fluoroscopy and also autoradiography.

  5. Mature students' perspectives of studying radiography

    Williams, M.; Decker, S.

    2009-01-01

    The study set out to explore the experiences of all final year mature students on a diagnostic radiography course, in one United Kingdom University. The aims were to identify any difficulties they may have had and to make recommendations to improve mature students' learning experiences with the hope of lowering attrition rates in this group. A qualitative study involving one-to-one audio recorded interviews was utilised. Analysis of the transcripts of interviews suggested that the group believed that their maturity and previous experiences helped them in the clinical environment and put them in a good position, when asked, to counsel younger students. However for some of the mature students these experiential skills did not extend fully into seeking appropriate support for themselves. The mature students were found to be highly motivated but there was a conflict between balancing clinical and academic aspects of studying as well as balancing studying with home life. The group was found to be unprepared for the volume of academic work and its detrimental effect on family life as they sacrificed other aspects of their lives in order to complete the course. It is recommended that forewarning and forearming prospective mature students be considered by radiography education providers. Setting up and utilising an on-line forum providing a 24/7 peer support environment would aid in coping with academic, clinical or personal problems

    Popp, Andrew; Murray, Allan

    2010-01-01

    This paper describes the need and new requirements to ensure the security of radioactive sources used in the practice of industrial radiography. We describe the discussions and issues arising during the september 2010 regional workshop held in Sydney on the application of security measures to industrial radiography practices. The workshop provided the perspectives of both radiation regulators and industry practitioners, including those from the Philippines. We describe the outputs of the workshop, and how they were developed, and make suggestions for further consideration and applications of security measures in the practice of industrial radiography.

    The successful and effectiveness of radiography method as a tool to increase quality level and safety of the engineering system and processing plants depend with the level of radiographer knowledge as service provider and also as supervisor. This book was published as effort several local experts to give their knowledge, theory and practical related to radiography technique to the involved public directly or indirectly. This book started with basic physic knowledge that becomes a root to radiography technology. Then, followed by discussion on tools and device that used in radiography work including x-ray machine, gamma projector, film, dark room, and others. Each aspect of radiograph quality also mentioned here to guide the reader on how to produce good radiograph that filled the specification wanted. The good radiograph does not mean anything if it failed to be interpreted correctly. Because of that, this book also explain how to choose good radiograph that qualified to be interpreted and after that how interpretation and evaluation process of object quality inspected was implemented based on image digestion that showed in radiograph. Several code and standard that usually applied in this country also will be referred as well for this work.

    Aim: The purpose of this article is to describe interdisciplinary comparison of the attributes of the concept of radiography in health sciences, physics and technology on the grounds of concept analysis. Background: The concept of radiography is widely used in health sciences, physics and technology. However, the content of the concept may vary. In order to clarify the concept of radiography, the concept must be systematically examined and defined in linguistic form. Method: The concept of radiography was analysed by using the evolutionary method of concept analysis. The data were collected through discretionary sampling and consisted of literature and Internet pages. Qualitative content analysis was employed for analysing the data. Findings: As a result of concept analysis, the concept of radiography in health sciences was determined as expertise of radiographers in the use of radiation, which is dual, dynamic, social and situation-related in nature, and typically based on versatile synthesis. Regarding the attributes identified, the concept of radiography has both similarities and differences between health sciences, physics and technology. Conclusions: The concept of radiography was found to be more abstract, wider, more complex and more radiographer-centred in health sciences than in other disciplines. The content of the concept of radiography seems to vary according to the discipline.

    BACKGROUND: New developments in processing of digital radiographs (DR), including multi-frequency processing (MFP), allow optimization of image quality and radiation dose. This is particularly promising in children as they are believed to be more sensitive to ionizing radiation than adults....... OBJECTIVE: To examine whether the use of MFP software reduces the radiation dose without compromising quality at DR of the femur in 5-year-old-equivalent anthropomorphic and technical phantoms. MATERIALS AND METHODS: A total of 110 images of an anthropomorphic phantom were imaged on a DR system (Canon DR...... with CXDI-50 C detector and MLT[S] software) and analyzed by three pediatric radiologists using Visual Grading Analysis. In addition, 3,500 images taken of a technical contrast-detail phantom (CDRAD 2.0) provide an objective image-quality assessment. RESULTS: Optimal image-quality was maintained at a dose...

    1985-01-01

    In accordance with the invention, collimating means are provided between the output screen of an X-ray image intensifier and the output of a television pickup. If a light collimator is used, this moves in synchronism with an X-ray collimator slit which is disposed between the X-ray source and the patient. The light collimator slit restricts the field of view of the television pickup to a limited area on the output screen of the image intensifier which corresponds to a portion of the image produced by direct radiation which reaches the input screen of the intensifier through the X-ray collimator slit. The light collimator prevents glare produced in the image intensifier tube from reaching the television pickup and contributing to background noise in the system and reduces the effects of off-focal radiation and scatter

  20. Are Private Providers more Productive and Efficient than Public Providers of International Education? Evidence from New Zealand

    2011-10-01

    Full Text Available This study has investigated the productivity growth and efficiency of private and public providers of international education in New Zealand. It has used secondary data to calculate the DEA-based Malmquist productivity index for measuring Total Factor Productivity (TFP-growth and efficiency of both public and private providers of international education during 1999-2010. The study has found that private providers experienced a larger TFP-growth than that of public providers during 1999-2004. However, they experienced a sharp decline in TFP-growth since 2005 through to 2010 and experienced a much smaller TFP-growth than that of public providers during this period. Conversely, public providers experienced a positive TFP-growth during 1999-2004 but they experienced a negative TFP-growth since 2005 through to 2010. Considering efficiency, both private and public providers experienced almost a constant Technical Efficiency Change (TEC having a same level of efficiency of one. Both private and public providers exhibited a constant return to scale during 1999-2010. This study argues that on an average, private providers are more productive than public providers of international education. However, they are not more efficient than public providers as both types of providers exhibited a constant return to scale during 1999-2010. This study also argues that TFP-growth of New Zealand’s international education was determined by Technological Change (TC, not by TEC during this period.

  1. Social media: The next frontier for professional development in radiography

    International Nuclear Information System (INIS)

    Lawson, Celeste; Cowling, Cynthia

    2015-01-01

    Background: Radiographers are required to undertake professional development in order to maintain registration. Professional development activities can be passive and isolate the practitioner. Social media is an interactive, collaborative, instant form of communication, which potentially addresses these concerns. Objectives: To establish whether the inherent challenges of social media use reduce its feasibility as a platform for professional development in radiography. Methods: A systematic review was undertaken using the PRISMA Guidelines. Academic databases were searched using pre-defined search terms, limits and inclusion criteria. Results: Zero reviewable papers were identified in the field of radiography globally. The search was expanded to “healthcare” and 810 papers were identified. After inclusion criteria and limits were applied, 12 papers were reviewed. Conclusions: Professional development using social media includes higher education, collaboration and networking. Managed with consideration to the inherent risks, social media provides a new means of inclusive professional development. - Highlights: • Professional development in radiography can draw on the benefits of social media. • Benefits of the social media platform are education, collaboration and networking. • Social media can reduce geographic and professional isolation. • Practitioners can share case studies and contribute professional opinions

    2004-01-01

    Industrial radiography is the oldest and most reliable non-destructive test method in the examination and two dimensional evaluation of weld defects. Digital radiographic methods provide more sensitive, faster and more reliable evaluation of defect images. One of the most important factors influencing the contrast and consequently the image quality is the noise on the film caused by scattered radiation. The digital image processing technique can eliminate the noise and improve the image quality. Digital radiography also enables three dimensional evaluation of weld defects. This work describes the use of digital radiography in the evaluation of defects in welds of different configurations by using a laser film digitizing system and an appropriate software programme. Advantages and limitations of the digital technique and conventional film radiography were discussed. (author)

    2016-01-01

    Purpose: To establish an understanding of patient safety within radiography education across Europe by surveying higher education institutions registered as affiliate members of the European Federation of Radiographer Societies (EFRS). Method: An online survey was developed to ascertain data on: programme type, patient safety definitions, relevant safety topics, specific areas taught, teaching and assessment methods, levels of teaching and curriculum drivers. Responses were identifiable in terms of educational institution and country. All 54 affiliated educational institutions were invited to participate. Descriptive and thematic analyses are reported. Results: A response rate of 61.1% (n = 33) was achieved from educational institutions representing 19 countries. Patient safety topics appear to be extremely well covered across curricula, however, topics including radiation protection and optimisation were not reported as being taught at an ‘advanced level’ by five and twelve respondents, respectively. Respondents identified the clinical department as the location of most patient safety-related teaching. Conclusions: Patient safety topics are deeply embedded within radiography curricula across Europe. Variations exist in terms of individual safety topics including, teaching and assessment methods, and the depth in which subjects are taught. Results from this study provide a baseline for assessing developments in curricula and can also serve as a benchmark for comparisons. - Highlights: • First European report on patient safety (PS). • PS deeply embedded within training curricula. • Terms and definitions largely consistent. • Some variety in the delivery and assessment methods. • Report provides baseline and opportunities for comparisons.

    Since radiography yields an image that can be easily related to the tested object, it is superior to many nondestructive testing techniques in revealing the size, shape, and location of certain types of discontinuities. The discussion is limited to a description of the radiographic process, examination of some of the quantitative aspects of radiography, and an outline of some of the new ideas emerging in radiography. The advantages of monoenergetic x-ray radiography and neutron radiography are noted

  8. PUBLIC AND PRIVATE HIGHER EDUCATION INSTITUTIONS IN MALAYSIA: COMPETING, COMPLEMENTARY OR CROSSBREEDS AS EDUCATION PROVIDERS

    Directory of Open Access Journals (Sweden)

    Wan Chang Da

    2007-01-01

    Full Text Available Delivery of higher education used to be exclusive to the public sector in Malaysia. However, legislative changes made in 1996 led to the coexistence of public and private higher education institutions. In 2007, there were 20 public universities compared to more than 500 private institutions, of which 30 are currently categorised as universities or university colleges. Looking at their respective roles as higher education providers, public and private institutions display characteristics of being substitutes while at the same time serving complementary roles to one another. This dichotomy between public and private higher education institutions can, in fact, be seen as inclining towards a hybrid model that allows both to operate within a single system of higher education provision in the country. Such a hybrid model is evident in how the clientele is being divided between public and private higher institutions. It is also evident in the different roles played by the respective faculty members as well as in the programmes being made available in either type of institutions.

    cumbersome and often exceeds the prescribed OH and S single person lifting limits. The role of industrial radiography has expanded to inspect not only welds and castings, so that it now includes inspection of assembled and processed goods ranging from automotive air-bags to canned food. It is also used in security systems at airports and other facilities. Almost all these applications use cabinet systems which are rarely the subject of serious radiation incidents or accidents. Gamma ray inspection no longer uses radium. The most common radio-isotopes in use now are Cobalt 60 and Iridium 192. Their freedom from the need for an electrical power supply; their high radiation energy and the ability to place a source in positions of limited physical access, ensures the ongoing attraction of the method. The useful activity ranges of typical sources vary according to their application and the effect on total inspection costs. Common source activities in Australia range between 185 and 370 GBq for Cobalt 60; and between 1500 and 3700 GBq for Iridium 192. Outside Australia however there are recent reports of routine industrial radiography using more than 5500 GBq of Iridium 192. Thus it can be appreciated that any radiation accidents involving these high activity sources have the potential for significant radiation doses. Personal Dose Data: ARPANSA and its predecessor, the Australian Radiation Laboratory, has been providing a personal radiation monitoring service for some time, and releases a summary report every few years (ARPANSA/TR 139, ARL/TR 121, ARL/TR 107). The selected data shown in Table 2 indicate a downward trend in occupational doses received by industrial radiographers working in open site situations, which are potentially the most hazardous. This trend is encouraging, especially when the number of industrial radiographers is increasing. A comparison of the ARPANSA data indicate that whilst the average Australian industrial radiographer's annual dose is higher than the

    Purpose: To establish the level of implementation of recommendations from the National Radiological Protection Board, relating to best radiation protection practice in dental radiography within general dental practices in the North-east of England. To survey the opinion of practitioners on the availability of related post-graduate courses in the region. Methods: A postal survey in the form of a self-reported questionnaire was mailed to all practices in the North-east of England in November 2000. The questionnaire, consisting of closed and open-ended questions, was to be completed where possible by the resident radiation protection supervisor. Results: Two hundred and sixteen practices responded to the questionnaire, a response rate of 53%. The survey revealed variation in the standards of application of best radiation protection practice. Some 23% of practitioners had not attended any post-graduate courses on radiation protection since qualifying. Post-graduate education provision on radiation protection in the region was considered insufficient by 51% of respondents. Conclusions: It is concluded that a significant proportion of practices were not making full use of opportunities to reduce dose to their patients. In addition, a small number of practices had untrained staff acting as the Radiation Protection Supervisor. A significant proportion of practitioners had not been updated in radiation protection practices within a 5-year period, and this may account for the failure to implement best radiographic practice. Over half felt that there was insufficient availability of post-graduate courses in radiation protection. The regional provision of continuing professional education in this field may need development

    Full Text Available The article is about the phenomenon of corruption in a comprehensive school. It analyses the expression forms of corruption and their peculiarities and disputes the main reasons stimulating educators to take part in corrupt interchanges thus tolerate it. On the ground of empirical research in Vilnius secondary schools it discloses attitudes of teachers, schoolchildren and parents towards corruption. The research was carried out in Vilnius Salomėja Nėris gymnasium, Vilnius Mikalojus Daukša secondary school, Mindaugas secondary school, Užupys gymnasium, Antakalnis gymnasium, Naujamiestis secondary school and Stanevičius secondary school. Overall 500 respondents were questioned: 300 pupils of ninth – twelfth forms, 100 teachers and 100 parents of schoolchildren. Difficult financial circumstances were pointed out as the main reason stimulating teachers to take part in corrupt interchanges. This answer was chosen by 42 per cent of respondents. Most of them think that raising wages would reduce corruption crimes. The research data show it is an important problem in schools though 70 per cent of respondents state it is not the biggest problem in their school. Only 15 per cent of questioned schoolchildren, 4 per cent of parents and 14 percent of teachers safely state that corruption is the main problem in their school. About 20 per cent of respondents (21.4 per cent of schoolchildren, 19 per cent of parents and 21 per cent of teachers acknowledge of making a payoff or receiving an offer to take it. Respondents state that 30 per cent of their friends and relatives made a payoff to school staff. 26.7 percent of schoolchildren and 27 per cent of parents’ acquaintances made a payoff to school staff. Only the answers of teachers did not change – 21 per cent of their colleagues were offered a payoff. These results do not let affirm that corruption is very widely spread in schools and therefore could be named as the biggest problem here. Though

    To gather data on educational program requirements for student membership in a state or national professional society, organization, or association. A 10-question online survey about student involvement in professional societies was emailed to 616 directors of Joint Review Committee on Education in Radiologic Technology (JRCERT)-accredited radiography programs. A total of 219 responses were received, for a 36% response rate. Of these, 89 respondents (41%) answered that their programs require students to join a professional organization. The society respondents most often required (70%) was a state radiography society. Sixty respondents (68%) answered that students join a society at the beginning of the radiography program (from matriculation to 3 months in). Of programs requiring student membership in professional societies, 42 (49%) reported that their students attend the state or national society annual conference; however, participation in activities at the conferences and in the society throughout the year is lower than conference attendance. Some directors stated that although their programs' policies do not allow membership mandates, they encourage students to become members, primarily so that they can access webinars and other educational materials or information related to the profession. Survey data showed that most JRCERT-accredited radiography programs support but do not require student membership in professional organizations. The data reveal that more programs have added those requirements in recent years. Increased student participation could be realized if programs mandated membership and supported it financially. ©2017 American Society of Radiologic Technologists.

    2014-01-01

    What is industrial radiography? It is a non-destructive method with a wide variety of applications, such as inspecting the quality of a weld. It uses high-energy radioactive sources or an X-ray generator.   Is this inspection technique used at CERN? Yes, it is widely used at CERN by the EN-MME Group, which outsources the work to one or more companies, depending on the workload. Is it possible to carry out radiography anywhere at CERN? Yes, it is possible to carry out radiography in any building/accelerator/experiment area at CERN (including in areas which are not normally subject to radiological hazards). When is radiography carried out? It normally takes place outside of working hours (7 p.m. to 6 a.m.). How will I know if radiography is taking place in my building? If this activity is planned in a CERN building, notices will be affixed to all of its main entrance doors at least 24 hours in advance. What are the risks? There is a risk of exposure to very high levels of radiation, dep...

  1. Muon radiography for exploration of Mars geology

    Directory of Open Access Journals (Sweden)

    S. Kedar

    2013-06-01

    Full Text Available Muon radiography is a technique that uses naturally occurring showers of muons (penetrating particles generated by cosmic rays to image the interior of large-scale geological structures in much the same way as standard X-ray radiography is used to image the interior of smaller objects. Recent developments and application of the technique to terrestrial volcanoes have demonstrated that a low-power, passive muon detector can peer deep into geological structures up to several kilometers in size, and provide crisp density profile images of their interior at ten meter scale resolution. Preliminary estimates of muon production on Mars indicate that the near horizontal Martian muon flux, which could be used for muon radiography, is as strong or stronger than that on Earth, making the technique suitable for exploration of numerous high priority geological targets on Mars. The high spatial resolution of muon radiography also makes the technique particularly suited for the discovery and delineation of Martian caverns, the most likely planetary environment for biological activity. As a passive imaging technique, muon radiography uses the perpetually present background cosmic ray radiation as the energy source for probing the interior of structures from the surface of the planet. The passive nature of the measurements provides an opportunity for a low power and low data rate instrument for planetary exploration that could operate as a scientifically valuable primary or secondary instrument in a variety of settings, with minimal impact on the mission's other instruments and operation.

    Diagnostic reference levels (DRLs) are an important tool in the optimisation of clinical radiography. Although national DRLs are provided for many diagnostic procedures including dental intra-oral radiography, there are currently no national DRLs set for cephalometric radiography. In the absence of formal national DRLs, the Health Protection Agency (HPA) has previously published National Reference Doses (NRDs) covering a wide range of diagnostic X-ray examinations. The aim of this study was to determine provisional NRDs for cephalometric radiography. Measurements made by the Dental X-ray Protection Service (DXPS) of the HPA, as part of the cephalometric X-ray equipment testing service provided to dentists and dental trade companies throughout the UK, were used to derive provisional NRDs. Dose-area product measurements were made on 42 X-ray sets. Third quartile dose-area product values for adult and child lateral cephalometric radiography were found to be 41 mGy cm² and 25 mGy cm², respectively, with individual measurements ranging from 3 mGy cm² to 108 mGy cm². This report proposes provisional NRDs of 40 mGy cm² and 25 mGy cm² for adult and child lateral cephalometric radiographs, respectively; these doses could be considered by employers when establishing their local DRLs.

    A lot of film radiography could be replaced by today's technologies in the field of digital radiography. Only few of these applications have indeed replaced film. The choice to go digital depends on cost, quality requirement, workflow and throughput. Digital images offer a lot of advantages in terms of image manipulation and workflow. But despite the many advantages, a lot of considerations are needed before someone can decide to convert his organization from conventional to digital radiography. This paper gives an overview of all different modalities that can be used in digital radiography with today's technologies, together with the experiences of the pioneers of digital radiography. Film Scanning, Computed Radiography and Digital Radiography by using of different kinds of flat panel detectors all have their specific application fields and customers. What is the status of the technology today, which advantages brings digital radiography, and which are the limitations radiographers have to consider when replacing film by digital systems. (author)

    entry to Japan would be useful for early detection of TB positive patients. Furthermore, it would be beneficial to conduct chest radiography screenings among students at language schools on a continuous basis. It is also necessary to provide health education to the staff and students in Japanese language schools. Effective methods of disseminating health education, especially on the topic of TB, should be considered.

    2017-08-01

    A reduction in racial disparities in maternal morbidity and mortality requires effective education of both patients and providers. Although providers seem to recognize that disparities exist, there is a widespread need for improving our understanding differences in health care and outcomes and the factors that contribute to them. There are increasingly more educational materials available for the purpose of augmenting disparities education among patients and providers. However, it is important to incorporate contemporary learning methodologies and technologies to address our current knowledge deficit. Collaborative educational models with a multi-disciplinary approach to patient education will be essential. Ultimately, the comprehensive education of providers and patients will require efforts on the part of numerous stakeholders within patient care delivery models. Further investigation will be necessary to determine how best to disseminate this information to maximize the impact of patient and provider educations with the goal of eliminating disparities in maternal morbidity and mortality.

    2007-01-01

    Conventional radiography requires access to two opposite sides of an object, which makes it unsuitable for the inspection of extended and/or thick structures (airframes, bridges, floors etc.). Backscatter imaging can overcome this problem, but the indications obtained are difficult to interpret. This paper applies the coded aperture technique to gamma-ray backscatter-radiography in order to enhance the detectability of flaws. This spatial coding method involves the positioning of a mask with closed and open holes to selectively permit or block the passage of radiation. The obtained coded-aperture indications are then mathematically decoded to detect the presence of anomalies. Indications obtained from Monte Carlo calculations were utilized in this work to simulate radiation scattering measurements. These simulated measurements were used to investigate the applicability of this technique to the detection of flaws by backscatter radiography

    Real-time radiography is used for imaging both dynamic events and static objects. Fluorescent screens play an important role in converting radiation to light, which is then observed directly or intensified and detected. The radiographic parameters for real-time radiography are similar to conventional film radiography with special emphasis on statistics and magnification. Direct-viewing fluoroscopy uses the human eye as a detector of fluorescent screen light or the light from an intensifier. Remote-viewing systems replace the human observer with a television camera. The remote-viewing systems have many advantages over the direct-viewing conditions such as safety, image enhancement, and the capability to produce permanent records. This report reviews real-time imaging system parameters and components

    The first thing industrial radiographers have to do before commencing radiography works is to determine manually the amount of correct exposure that the film need to be exposed in order to obtain the right density. The amount of exposure depends on many variables such as type of radioisotope, type of film, nature of test-object and its orientation, and specific arrangement related to object location and configuration. In many cases radiography works are rejected because of radiographs fail to meet certain reference criteria as defined in the applicable standard. One of the main reasons of radiograph rejection is due to inadequate exposure received by the films. SIMPLE is a software specially developed to facilitate the calculation of gamma-radiography exposure. By using this software and knowing radiographic parameters to be encountered during the work, it is expected that human error will be minimized, thus enhancing the quality and productivity of NDT jobs.

    After a brief explanation of the basics of electricity, the fundamentals of radiography are dealt with in more detail - the discovery of X-rays, their nature and properties, the production of the X-ray image and ways of improving the image. A chapter is devoted to the important subject of radiation protection. Explanations are given of the use of the Siemens exposure tables, which make it simpler to modify exposures from the values given in the tables. There is also a section on some of the standard radiographic positioning for patients. The most common medical terms used in radiography and fluoroscopy are listed and an Appendix gives details of the major items of Siemens X-ray equipment. There is a list of literature recommended for further study. Theoretical explanations have been kept to a minimum so that information that is important to radiography can be emphasized. (orig./MG)

    1988-01-01

    In patients with longstanding and/or deep pressure ulcers radiology is usually consulted. Survey radiography and sinography in 14 patients with pressure ulcers (6 over the tuber ischii and 8 over the femoral trochanter) were evaluated. Osteomyelitic involvement of adjacent bone was revealed in 9 patients on survey radiography. However, it was usually impossible to assess whether or not bony involvement represents healed or active osteomyelitis. Sinography did not contribute to the assessment of whether or not adjacent cortical bone was involved. However, when a fistulation to an adjacent joint was revealed this contributed substantially to the preoperative planning of resection. We therefore recommend that survey radiography and sinography should be included in the evaluation of these patients but that the results from such examinations are critically evaluated. Joint involvement should be taken seriously as progression of septic arthritis usually occurs rapidly. (orig.)

    Compton radiography permits an acquisition of direct magnification Compton radiograms by use of a pinhole collimator, rendering it feasible to overcome the resolution of the scinticamera being employed. An improvement of resolution was attained from 7 mm to 1 mm separation. Usefulness of its clinical application can be seen in orientation of puncture and biopsy in deep structures and detection of various foreign bodies penetrated by blasts and so on under the ''magnification Compton fluoroscopy'' which can be developed on this principle in the near future.

    2002-01-01

    Purpose: The purpose of this research was to identify the extent and scope of changes to radiography practice. Method: Questionnaires were sent to radiology managers at acute National Health Service (NHS) hospitals in 2000 as a follow-up to an initial survey conducted in 1998. Information was sought on region, teaching/non-teaching status, the nature of extended role tasks undertaken and the year in which these tasks were first undertaken. Results: Some 172 questionnaires were returned from a total of 253 dispatched (68%). In 161 hospitals radiographers administered intravenous injections and performed barium enemas in 119 hospitals, while a red-dot system was in operation in 141 hospitals. Reporting by radiographers had increased since 1998. Replies indicated that, at 124 hospitals, radiographers were reporting in ultrasound. Skeletal reporting was the second most-frequently-reported activity, with 63 hospitals indicating that radiographers reported in this modality, while barium enemas were reported by radiographers in 34 hospitals. Reporting was also undertaken by radiographers in mammography, nuclear medicine, paediatrics and chest radiography in a small minority of hospitals. There was no statistically significant difference between the adoption of tasks in non-teaching and teaching hospitals with the exception of radiographer-performed barium enemas (P=0.014) and red-dot systems (P=0.05). Radiographers were more likely to undertake both of these activities at non-teaching hospitals than in teaching hospitals. Regional differences were apparent in reporting, with a greater prevalence in the English regions than Northern Ireland, Scotland and Wales. Conclusion: The study provided data that demonstrated the extent to which hospitals are utilizing the developing skills of radiographers. This has important implications for future education and training needs for radiographers and for delivery of imaging services

  19. Radiation protection and safety in industrial radiography

    International Nuclear Information System (INIS)

    1999-01-01

    The use of ionizing radiation, particularly in medicine and industry, is growing throughout the world, with further expansion likely as technical developments result from research. One of the longest established applications of ionizing radiation is industrial radiography, which uses both X radiation and gamma radiation to investigate the integrity of equipment and structures. Industrial radiography is widespread in almost all Member States. It is indispensable to the quality assurance required in modern engineering practice and features in the work of multinational companies and small businesses alike. Industrial radiography is extremely versatile. The equipment required is relatively inexpensive and simple to operate. It may be highly portable and capable of being operated by a single worker in a wide range of different conditions, such as at remote construction sites, offshore locations and cross-country pipelines as well as in complex fabrication facilities. The associated hazards demand that safe working practices be developed in order to minimize the potential exposure of radiographers and other persons who may be in the vicinity of the work. The use of shielded enclosures (fixed facilities), with effective safety devices, significantly reduces any radiation exposures arising from the work. This Safety Report summarizes good and current state of the art practices in industrial radiography and provides technical advice on radiation protection and safety. It contains information for Regulatory Authorities, operating organizations, workers, equipment manufacturers and client organizations, with the intention of explaining their responsibilities and means to enhance radiation protection and safety in industrial radiography

    Non-destructive testing in the form of radiography is an inherent part of the manufacturing process. In the development stage - it helps locating physical discontinuities of the component and provides a feedback to specify suitable process, and balanced acceptance criteria, keeping in view the cost of manufacture and demands of specification and performance. In the manufacturing stage - it locates the discontinuities occurring at various stages of manufacture, ensuring timely intervention to prevent the production of scrap and/or rework and loss of energy. In the operation stage, it helps in-service and on-line monitoring of components and plants to avert and ensure planned minimum shutdowns

    Although adolescence is marked by profound and dynamic changes, it is virtually neglected by health care providers, by society, and even by most parents, teachers, and health professionals. The aim of this study was to investigate barriers to health education in adolescents from health care providers' views compared to teens. The study population consisted of 72 health care providers and 402 high school female students in Northern Iran in 2012. They completed a self-administered questionnaire about their views on barriers to adolescents' health education. It is revealed that the major barrier to adolescents' health education from a health care providers' perspective is "Lack of private room for adolescents' health education", while "Lack of adolescents' interest to content of educational programs" is a significantly greater barrier to health education among adolescents. The results suggest that for adolescent health education, specific strategies should be used in adolescent health promotion programs.

    In Industrial Radiography, there are many criteria that need to be considered based on established standards to accept or reject the radiographic film. For conventional radiography, we need to consider the optical density by using the densitometer when viewing the film on the viewer. But in the computed radiography (CR) we need to evaluate and performed the analysis from the quality of the digital image through grey value. There are many factors that affected the digital image quality. One of the factors which are affected to the digital image quality in the image processing is grey value that related to the contrast resolution. In this work, we performed grey value study measurement on digital radiography systems and compared it with exposed films in conventional radiography. The test sample is a steel step wedge. We found out the contrast resolution is higher in Computed Radiography compared with Conventional Radiography. (author)

    The aim of this study was to evaluate the efficacy of conventional radiography, digital radiography and ultrasound imaging in diagnosing periapical lesions. Twenty-one patients aged between 15 and 45 years with well defined periapical radiolucency associated with anterior maxillary or mandibular teeth requiring endodontic surgery or extraction were selected and consented to the study. Preoperative intraoral periapical radiographs and digital images using charge-coupled device obtained by paralleling technique were assessed by 3 specialist observers who gave their diagnosis of the periapical lesions. Then ultrasound examination was performed and the images were assessed for size, contents, and vascular supply by 3 ultrasonographers. It was followed by curettage of periapical tissues to enable histopathologic investigation, which is the gold standard in diagnosis. The data were statistically analyzed using SPSS, analysis of variance, and kappa statistics. The percentage accuracy of diagnosing periapical lesions using conventional radiography was 47.6%, digital radiography 55.6%, and ultrasound 95.2%. Ultrasound had the highest sensitivity and specificity: 0.95 and 1.00, respectively. Conventional and digital radiography enable diagnosis of periapical diseases, but not their nature, whereas ultrasound provides accurate information on the pathologic nature of the lesions, which is of importance in predicting the treatment outcome. Therefore ultrasound can be used as an adjunct to conventional or digital radiography in diagnosing periapical lesions. Copyright (c) 2010 Mosby, Inc. All rights reserved.

    Whilst numerous studies have investigated nurses' compliance with hand hygiene and use of alcohol-based hand rub (ABHR), limited attention has been paid to these issues in allied health staff. Reports have linked infections to breaches in infection control in the radiography unit (RU). With advances in medical imaging, a higher proportion of patients come into contact with RU staff increasing the need for good hand hygiene compliance. This study aimed to evaluate effectiveness on compliance of an intervention to improve awareness of hand hygiene in the RU of a district hospital. A quasi-experimental study design including questionnaires assessing knowledge and attitudes of hand hygiene and direct observation of participants was used to evaluate an educational programme on hand hygiene of the RU of a large district hospital. All healthcare workers (HCW), comprising 76 radiographers, 17 nurses, and nine healthcare assistants (HCA), agreed to participate in the study. Of these, 85 completed the initial and 76 the post-test anonymous questionnaire. The hand hygiene compliance of all 102 HCW was observed over a 3-week period prior to and after the intervention. The 2-month intervention consisted of talks on hand hygiene and benefits of ABHR, provision of visual aids, wall-mounted ABHR dispensers, and personal bottles of ABHR. Before the intervention, overall hand hygiene compliance was low (28.9 %). Post-intervention, compliance with hand hygiene increased to 51.4 %. This improvement was significant for radiographers and HCA. Additionally, knowledge and attitudes improved in particular, understanding that ABHR can largely replace handwashing and there is a need to perform hand hygiene after environmental contact. The increased use of ABHR allowed HCW to feel they had enough time to perform hand hygiene. The educational intervention led to increased awareness of hand hygiene opportunities and better acceptance of ABHR use. The reduced time needed to perform hand

    A technique for retrograde contrast radiography of the distal portions of the intestinal tract of foals was developed and then performed in 25 foals (1 to 30 days old) with colic. Retrograde contrast radiography was shown to be sensitive (100%) and specific (100%) for evaluating obstruction of the small colon or transverse colon. It was slightly less sensitive (86%) and specific (83%) for evaluation of the entire large colon, particularly in older foals. Retrograde contrast radiography provided increased diagnostic capability, compared with that for noncontrast radiography. Retrograde contrast radiography can provide valuable information when evaluating foals with colic and should be part of the diagnostic evaluation

    Patients' and their significant others' education during the perioperative phase is an important and challenging aspect of care. This study explored the content of education provided by nurses to arthroplasty patients and their significant others. Data were collected with the Education of Patients-NURSE content (EPNURSE-Content), Received Knowledge of Hospital Patient (RKhp), and Received Knowledge of Significant Other (RKso) scales. The results showed that the content of education emphasized biophysiological and functional needs, differed between countries, and was related to how physically demanding nurses found their job to be and the amount of education provided. There is congruence between the received knowledge of patients and their significant others in relation to the content of education provided by nurses. The findings can support nurses in developing aid material for patients and significant others explaining the nature of education and advising them what to expect and how to optimize their participation in the process.

  16. Basic principles of industrial radiography

    International Nuclear Information System (INIS)

    Bestbier, P.

    1983-01-01

    X-ray radiography and gamma radiography are used in industrial radiography. X-rays and gamma rays have the ability to penetrate materials and be absorbed by different densities. This characteristic makes them useful tools in industrial and medical radiography. The sources used for the generation of x-rays, gamma rays and radioisotopes are discussed. Films are one of the recording methods of x-radiography. The article also deals with advantages and disadvantages of radiography. Factors governing radiation exposure includes: the type of radiation source, material to be radiographed, distance, film, and the method for development. International specifications are also responsible for strict control over the standard of workmanship in industrial radiography

    Therapeutic patient education programmes on heart failure have been widely proposed for many years for heart failure patients, but their efficiency remains questionable, partly because most articles lack a precise programme description, which makes comparative analysis of the studies difficult. To analyse the degree of precision in describing therapeutic patient education programmes in recent randomized controlled trials. Three major recent recommendations on therapeutic patient education in heart failure inspired us to compile a list of 23 relevant items that an 'ideal' description of a therapeutic patient education programme should contain. To discover the extent to which recent studies into therapeutic patient education in heart failure included these items, we analysed 19 randomized controlled trials among 448 articles published in this field from 2005 to 2012. The major elements required to describe a therapeutic patient education programme were present, but some other very important pieces of information were missing in most of the studies we analysed: the patient's educational needs, health literacy, projects, expectations regarding therapeutic patient education and psychosocial status; the educational methodology used; outcomes evaluation; and follow-up strategies. Research into how therapeutic patient education can help heart failure patients will be improved if more precise descriptions of patients, educational methodology and evaluation protocols are given by authors, ideally in a standardized format.

The purpose of this study was to examine how patient, physician, and situational factors are associated with the extent to which providers educate patients about glaucoma and glaucoma medications, and which patient and provider characteristics are associated with whether providers educate patients about glaucoma and glaucoma medications. Methods. Patients with glaucoma who were newly prescribed or on glaucoma medications were recruited and a cross-sectional study was conducted at six ophthalmology clinics. Patients’ visits were videotape recorded and patients were interviewed after visits. Generalized estimating equations were used to analyze the data. Results. Two hundred and seventy-nine patients participated. Providers were significantly more likely to educate patients about glaucoma and glaucoma medications if they were newly prescribed glaucoma medications. Providers were significantly less likely to educate African American patients about glaucoma. Providers were significantly less likely to educate patients of lower health literacy about glaucoma medications. Conclusion. Eye care providers did not always educate patients about glaucoma or glaucoma medications. Practice Implications. Providers should consider educating more patients about what glaucoma is and how it is treated so that glaucoma patients can better understand their disease. Even if a patient has already been educated once, it is important to reinforce what has been taught before.

    Two decades have passed since the publication of laboratory studies of satisfaction of search (SOS) in chest radiography. Those studies were performed using film. The current investigation tests for SOS effects in computed radiography of the chest. Sixty-four chest computed radiographs half demonstrating various "test" abnormalities were read twice by 20 radiologists, once with and once without the addition of a simulated pulmonary nodule. Receiver-operating characteristic detection accuracy and decision thresholds were analyzed to study the effects of adding the nodule on detecting the test abnormalities. Results of previous studies were reanalyzed using similar modern techniques. In the present study, adding nodules did not influence detection accuracy for the other abnormalities (P = .93), but did induce a reluctance to report them (P chest radiography (P chest radiography has changed, but it is not clear why. SOS may be changing as a function of changes in radiology education and practice. Copyright © 2015 AUR. Published by Elsevier Inc. All rights reserved.

  3. Opportunities for TRIGA reactors in neutron radiography

    International Nuclear Information System (INIS)

    Barton, John P.

    1978-01-01

    In this country the two most recent installations of TRIGA reactors have both been for neutron radiography, one at HEDL and the other at ANL. Meanwhile, a major portion of the commercial neutron radiography is performed on a TRIGA fueled reactor at Aerotest. Each of these installations has different primary objectives and some comparative observations can be drawn. Another interesting comparison is between the TRIGA reactors for neutron radiography and other small reactors that are being installed for this purpose such as the MIRENE slow pulse reactors in France, a U-233 fueled reactor for neutron radiography in India and the L88 solution reactor in Denmark. At Monsanto Laboratory, in Ohio, a subcritical reactor based on MTR-type fuel has recently been purchased for neutron radiography. Such systems, when driven by a Van de Graaff neutron source, will be compared with the standard TRIGA reactor. Future demands on TRIGA or competitive systems for neutron radiography are likely to include the pulsing capability of the reactor, and also the extraction of cold neutron beams and resonance energy beams. Experiments recently performed on the Oregon State TRIGA Reactor provide information in each of these categories. A point of particular current concern is a comparison made between the resonance energy beam intensity extracted from the edge of the TRIGA core and from a slot which penetrated to the center of the TREAT reactor. These results indicate that by using such slots on a TRIGA, resonance energy intensities could be extracted that are much higher than previously predicted. (author)

    2006-01-01

    The purpose of this study was to: (1) determine the popularity of digital radiography among members of the American Academy of Pediatric Dentistry (AAPD); and (2) report the most common systems in use. An AAPD-approved, voluntary, and anonymous electronic survey was developed and sent to 923 board certified pediatric dentists. Years in practice and in-office x-ray technology (digital or conventional) were inquired about initially. If negative for the use of digital radiography, future consideration for converting to digital radiography was ascertained. For positive responses, more in-depth information was requested. Information on type of system (sensor or phosphor plate), user friendliness, diagnostic ability, patient's comfort, general costs, durability, and parental and overall satisfaction was collected. For most of the questions, a 5-point assessment scale was used. Opportunity for additional comments was provided upon survey completion. Data was analyzed using descriptive statistics. A 32% (296/923) response rate was obtained. Twenty-six percent of practitioners (78/296) implemented digital radiography in their practices, whereas 71% considered future acquisition. Similar distribution for sensor and phosphor plate users was found. Sensor technology was reported to produce faster images, but was less tolerable by young children due to size and thickness. Phosphor plates were considered more children friendly, less expensive, and less durable. Parental satisfaction was very high with great marketing value. Picture quality was comparable to conventional film. Overall, digital radiography users would recommend it to other pediatric dentists. Digital radiography is not yet popular among pediatric dentists. Cost reduction and technology advancement may enhance utilization.

    How do we reach the public with the exciting story of Solar System Exploration? How do we encourage girls to think about careers in science, math, engineering and technology? Why should NASA scientists make an effort to reach the public and informal education settings to tell the Solar System Exploration story? These are questions that the Solar System Exploration Forum, a part of the NASA Office of Space Science Education (SSE) and Public Outreach network, has tackled over the past few years. The SSE Forum is a group of education teams and scientists who work to share the excitement of solar system exploration with colleagues, formal educators, and informal educators like museums and youth groups. One major area of the SSE Forum outreach supports the training of Girl Scouts of the USA (GS) leaders and trainers in a suite of activities that reflect NASA missions and science research. Youth groups like Girl Scouts structure their activities as informal education.

    1980-01-01

    Our program on heavy-ion radiography began soon after heavy ions were accelerated to high energies. Heavy ions are capable of very high electron density discrimination combined with good radial image resolution and low dose. Since heavy-ion beams produce many secondries, plastic nuclear detectors have an advantage for recording heavy-ion images. Projection imaging is now a practical technique that can resolve density differences between normal tissue and tumor tissue in some cases in which X rays could not make a distinction. Initial attempts at heavy-ion tomography also indicate potential for high resolution in this field. The physical basis for heavy-ion radiography and tomographic reconstruction studies are discussed in detail

    It has been pointed out that medical exposures are the most significant sources of exposure to ionizing radiation for the general population. Inside the medical exposures the most important is the X-ray use for diagnosis, which is by far the largest contribution to the average dose received by the population. From all studies performed in radiology the chest radiography is the most abundant. In an X-ray machine, voltage and current are combined to obtain a good image and a reduce dose, however due to the workload in a radiology service individual dose is not monitored. In order to evaluate the dose due to chest radiography in this work a plate phantom was built according to the ISO recommendations using methylmethacrylate walls and water. The phantom was used in the Imaging department of the Zacatecas General Hospital as a radiology patient asking for a chest study; using thermoluminescent dosimeters, TLD 100 the kerma at the surface entrance was determined.

    We have developed a system of quantitative radiography in order to produce quantitative images displaying homogeneity of parts. The materials that we characterize are synthetic composites and may contain important subtle density variations not discernible by examining a raw film x-radiograph. In order to quantitatively interpret film radiographs, it is necessary to digitize, interpret, and display the images. Our integrated system of quantitative radiography displays accurate, high-resolution pseudo-color images in units of density. We characterize approximately 10,000 parts per year in hundreds of different configurations and compositions with this system. This report discusses: the method; film processor monitoring and control; verifying film and processor performance; and correction of scatter effects

  10. 'That would have been beneficial': LGBTQ education for home-care service providers.

    Daley, Andrea; MacDonnell, Judith A

    2015-05-01

    This paper reports qualitative findings from a pilot study that explored the lesbian, gay, bisexual, transgender and queer (LGBTQ) education needs of home-care service providers working in one large, urban Canadian city. The pilot study builds upon research that has documented barriers to health services for diversely situated LGBTQ people, which function to limit access to good-quality healthcare. LGBTQ activists, organisations and allies have underscored the need for health provider education related to the unique health and service experiences of sexual and gender minority communities. However, the home-care sector is generally overlooked in this important body of research literature. We used purposeful convenience sampling to conduct four focus groups and two individual interviews with a total of 15 professionally diverse home-care service providers. Data collection was carried out from January 2011 to July 2012 and data were analysed using grounded theory methods towards the identification of the overarching theme, 'provider education' and it had two sub-themes: (i) experiences of LGBTQ education; and (ii) recommendations for LGBTQ education. The study findings raise important questions about limited and uneven access to adequate LGBTQ education for home-care service providers, suggest important policy implications for the education and health sectors, and point to the need for anti-oppression principles in the development of education initiatives. © 2014 John Wiley & Sons Ltd.

    Apparatus is described for improving the handling rate of patients in panoramic dental radiography when tube head-camera assembly of a low silhouette panoramic dental X-ray machine is rotated for a scan in one direction only. This is effected by fast return of the tube head-camera assembly with its simultaneous elevation, thus facilitating the radiographed patient's exit from the machine and the entrance of another patient. Fast speed is about twice the scanning speed. (author)

    Tomographic images of an object are obtainable by irradiating it with a collimated beam of monochromatic gamma rays and recording the resultant Compton rays scattered upward at right angles. This is the scattered-ray principle of the formation of a radiation image that differs from the traditional ''silhouette principle'' of radiography, and that bears prospects of stereopsis as well as cross-section tomography.

    The medical application of radiography has gained wider study since diagnostic radiology plays a very important role in modern medicine for fast diagnosis and therapy. Digital radiography is a relatively new technology that promises greater accuracy, lesser dose and better manipulation of patient radiology images in hospitals. In this study, a general discussion on digital radiography has been presented. The presentation focuses on the optimisation of doses to patients in the medical application of digital radiography, quality control and quality assurance. A brief presentation on performance indicators in digital radiography has also been presented. The advantages of digital radiography over the conventional film/screen system have been elaborated and its limitations are also outlined. (author)

    1983-06-01

    The aim of the present standard is to fix the rules for the construction of gamma radiography instrumentation without prejudice to the present regulations. These apparatus have to be fitted with only sealed sources conformable to the experimental standard M 61-002. The present standard agrees with the international standard ISO 3999 of 1977 dealing with the same subject. Nevertheless, it is different on the three main following points: it does not accept the same limits of absorbed dose rates in the air calculated on the external surface of projectors; it precribes tightness, bending, crushing and tensile tests for some components of the gamma radiography it prescribes tests of endurance and resistance to breaking for the locking systems of the gamma radiography apparatus. The present standard also specifies the following points: symbols and indications to put on projectors and on the source-holder; identification of the source contained in the projector; and, accompanying documents. The regulation references are given in annexe [fr

    2008-01-01

    There are thousands of valves in a nuclear power plant (NPP) used for control, safety and checks in various plant systems, so there is a well-identified need for fast and reliable inspection and diagnostics of valves. Digital radiography can provide considerable improvements to the inspection and testing procedures for valves in comparison to classical film radiography. These improvements can lead to significant financial advantages by providing real-time inspection results, significantly reduced inspection and decision-making time, and reduced operational cost. Digital image processing, including digital image enhancement, digital archiving, and digital communication of the images and the results, is also a considerable advantage over classical film radiography technology. Another advantage of digital radiography technology is the improved safety and the reduced environmental impact due to reduced exposure/test times, use of smaller exclusion zones, elimination of chemical processing, and absence of disposable materials. This paper reviews the existing technology and evaluates the potential of digital radiography for inspection and diagnostics of valves. Station needs and requirements are assessed, and the safety, environmental and economical constraints of digital radiography techniques estimated. The advantages and disadvantages of different digital radiography equipment are compared, and their limitations and characteristics studied. (author)

    Patient education is a critical component of the patient-centered medical home and is a powerful and effective tool in chronic disease management. However, little is known about the effect of practice payment on rates of patient education during office encounters. For this study we took data from the 2009 National Ambulatory Medical Care Survey. This was a cross-sectional analysis of patient visits to primary care providers to determine whether practice payment in the form of capitated payments is associated within patient education being included more frequently during office visits compared with other payment methods. In a sample size of 9863 visits in which capitation status was available and the provider was the patient's primary care provider, the weighted percentages of visits including patient education were measured as a percentages of education (95% confidence intervals): 75% capitation, 74.0% (52.2-88.1). In an adjusted logistic model controlling for new patients (yes/no), number of chronic conditions, number of medications managed, number of previous visits within the year, and age and sex of the patients, the odds of receiving education were reported as odds ratios (95% confidence intervals): 75% capitation, 3.38 (1.23-9.30). Patients are more likely to receive education if their primary care providers receive primarily capitated payment. This association is generally important for health policymakers constructing payment strategies for patient populations who would most benefit from interventions that incorporate or depend on patient education, such as populations requiring management of chronic diseases.

    At present, there is no standard way of evaluating performance characteristics of digital radiography systems. Continuous measurements of performance parameters are necessary in order to obtain images of high quality. Parameters of quality assurance in digital radiography, which can be evaluated with simple, quick methods, are spatial resolution, low-contrast detectability, dynamic range and exposure dose. Spatial resolution was determined by a lead bar pattern, whereas the other parameters were measured by commercially available phantoms. Performance measurements of 10 digital subtraction angiography (DSA) units and one digital radiography system for unsubtracted digital radiography were assessed. From these results, recommendations for performance parameter levels will be discussed. (author)

    Digital projection radiography provides digital data in X-ray examinations, which used to be carried out by examinations screen-film system combinations. The technological basis and clinical performances of digital luminescent radiography (DLR) and digital radiography are reviewed. Digital projection radiography does not allow to reduce selenium exposure significantly, compared to screen-film system combinations. Digital luminescent radiography can be used for the entire spectrum of analogous projection radiography the only exception being extremely subtile structural changes. The clinical experiences with digital selenium radiography achieved so far in chest X-rays are promising and the technique is expected to be increasing used in other anatomic regions as well. (orig.)

    Radiography is the ancillary test of choice for lameness in cattle. Osseous lesions due to osteoporosis, osteitis or osteomyelitis and sequestrae can be visualised. Radiography is the only ancillary examination that provides a thorough investigation of the lesion affecting a bovine presented with a non-weight bearing suspected fracture and limb inflammation associated with soft tissue crepitation. Radiography is the only method to ensure that the fracture is not open. It facilitates follow-up of healing of osseous lesions. The period of time required for immobilisation can be adjusted depending on the type of lesions [it

    2014-11-01

    Information crucial to the diagnosis and treatment of feline oral diseases can be ascertained using dental radiography and the inclusion of this technology has been shown to be the best way to improve a dental practice. Becoming familar with the techniques required for dental radiology and radiography can, therefore, be greatly beneficial. Novices to dental radiography may need some time to adjust and become comfortable with the techniques. If using dental radiographic film, the generally recommended 'E' or 'F' speeds may be frustrating at first, due to their more specific exposure and image development requirements. Although interpreting dental radiographs is similar to interpreting a standard bony radiograph, there are pathologic states that are unique to the oral cavity and several normal anatomic structures that may mimic pathologic changes. Determining which teeth have been imaged also requires a firm knowledge of oral anatomy as well as the architecture of dental films/digital systems. This article draws on a range of dental radiography and radiology resources, and the benefit of the author's own experience, to review the basics of taking and interpreting intraoral dental radiographs. A simplified method for positioning the tubehead is explained and classic examples of some common oral pathologies are provided. © ISFM and AAFP 2014.

    2015-02-01

    This project reviewed published IAEA materials and other documents on safety culture with specific references to industrial radiography. Safety culture requires all duties important to safety to be carried out correctly, with alertness, due thought and full knowledge, sound judgment and a proper sense of accountability. The development and maintenance of safety culture in an operating organization has to cover management systems, policies, responsibilities, procedures and organizational arrangements. The essence is to control radiation hazard, optimize radiation protection to prevent or reduce exposures and mitigate the consequences of accidents and incidents. To achieve a high degree of safety culture appropriate national and international infrastructure should exist to ensure effective training of workers and management system that supports commitment to safety culture at all level of the organization; management, managers and workforce. The result of the review revealed that all accidents in industrial radiography facilities were due to poor safety culture practices including inadequate regulatory control oversight. Some recommendations are provided and if implemented could improve safety culture leading to good safety performance which will significantly reduce accidents and their consequences in industrial radiography. These examples call for a review of safety culture in Industrial radiography. (au)

    Neutron radiography provides an efficient tool of measurement for many applications in fundamental research as well as in industrial non-destructive testing (NDT). A neutron radiography program has been initiated at the Paul Scherrer Institute and implemented since 1992. From the beginning of 1992 until the end of 1993, a neutron facility has been in operation at the SAPHIR research reactor. Several applications have been tested and programs on two main fields of application have been established, focusing on the study of porous materials, especially concrete and granitic rock. The investigations on concrete and other building materials are carried out in cooperation with the Swiss Federal Institute of Technology in Zurich. The experimental activities are currently carried out at the Atominstitute of the Austrian Universities in Vienna, in the framework of a cooperation program with the Atominstitute. The continuation of the activities on a new radiography facility at the spallation source SINQ is planned at the Paul Scherrer Institute. In the following an overview of the method, of the actual and potential applications of neutron radiography at the Paul Scherrer Institute is given. (author) 6 figs., 1 tab., 3 refs

    Patients experiencing cancer also can experience anxiety. Moderate to severe levels of anxiety can interfere with patients' ability to concentrate and comprehend new information. The condition is particularly troublesome when trying to present educational material related to recommended treatment interventions. Patients' understanding of the material is critical to ensure informed consent. Informed consent can be compromised if patients are unable to understand the information being provided. Nurses must be cognizant of the impact that anxiety has on patient education and assess patients prior to initiating patient teaching. By managing anxiety before beginning education, nurses can provide an environment more conducive to learning.

    Digital X-ray imaging technology has advanced rapidly over the past few years. This review, particularly aimed at those involved in using and purchasing such technology, is an attempt to unravel some of the complexities of this potentially confusing subject. The main groups of X-ray imaging devices that are considered are digitisers of conventional radiographs, image-intensifier-based fluorography systems, photostimulable phosphor computed radiography, amorphous selenium-based technology for thorax imaging and flat-panel systems. As well as describing these different systems, we look at ways of objectively assessing their image quality. Concepts that are used and explained include spatial resolution, grey-scale bit resolution, signal-to-noise ratio and detective quantum efficiency. An understanding of these basic parameters is vital in making a scientific assessment of a system's performance. Image processing and techniques are also briefly discussed, particularly with reference to their potential effects on image quality. This review aims to provide a basic understanding of digital X-ray imaging technology and enables the reader to make an independent and educated assessment of the relative merits of each system.

    2007-04-01

    This paper explores the notion of educational partnerships and reports on research on client provider partnerships between full primary schools and external technology education providers for Year 7 and 8 New Zealand students (age range approx. 12 to 13 years). Educational reforms in New Zealand and the introduction of a more holistic technology education curriculum in 1995 changed the nature of the relationship between the technology education partners. The research sought to identify, from the perspective of the primary schools (clients), factors that contribute to successful partnerships between them and their technology education provider. A mixed methods approach consisting of a survey of client schools, in-depth interviews and a series of four in-depth case studies (drawing on issues derived from the survey) was employed. Issues relating to teacher subculture, leadership roles and inflexibility of official processes all surfaced. The research points to an absence of commitment, shared understanding, shared power, leadership, communication and accountability in many educational partnerships that were the focus of this work.

    The success of educational interventions depends on the integration of educational programs into clinical practice. To determine the educational needs and perceived barriers of people living with HIV (PHIV) and their health care providers (HCP). Qualitative study conducted in 60 PHIV and 10 HCP. For data collection, a semi-structured in-depth interview was applied, addressing the educational needs (content, methodology, person, time, physical location) and identified barriers to implement an educational program for PHIV Content analysis technique was used for data analysis. PHIV and their HCP identified the same educational needs as the following: general-related content, psychological, sexual and secondary prevention aspects of the disease. Individual sessions with written material and web pages were identified as important resources to support education. Both PHIV and professionals expressed their willingness to participate in educational programs, but the most commonly identified barrier was lack of time. This study identifies the key elements to include in an educational program for Chilean PHIV from the user and professional perspective.

    Schulz, Michael L.

    2010-08-20

    In this thesis I present a new technique for the spatially resolved investigation of the magnetic properties of bulk samples. Standard one dimensional neutron depolarisation analysis is combined with neutron radiography to a method we call Neutron Depolarisation Imaging (NDI). The experimental setup which was installed at the neutron radiography beam line ANTARES at FRM II consists of a double crystal monochromator, neutron polariser, spin flipper, polarisation analyser and a position sensitive CCD detector. A comprehensive discussion of the requirements for these components is given and the limitations of the method are shown. The maximum spatial resolution which can be achieved with a neutron radiography setup is determined by the collimation of the neutron beam and the distance between sample and detector. Different types of polarisers have been tested and their advantages and disadvantages are discussed. A double crystal monochromator and a new type of polariser employing polarising neutron supermirrors based on the principle of an optical periscope were developed and tested during this work. Furthermore, NDI measurements on various samples of the weakly ferromagnetic materials Pd{sub 1-x}Ni{sub x} and Ni{sub 3}Al are presented. Neutron depolarisation radiography and tomography measurements were conducted with a spatial resolution as high as 0.3 mm on Pd{sub 1-x}Ni{sub x} and Ni{sub 3}Al samples. The feasibility of NDI experiments under hydrostatic pressures up to 10 kbar was shown on a sample of Ni{sub 3}Al using a modified Cu:Be clamp cell. A decrease of the ordering temperature by 2 K under hydrostatic pressure was determined from the NDI measurements and shows the potential of the method for further high pressure experiments. Additionally a method was developed which in principle allows to obtain the intrinsic dependence of the ordering temperature T{sub C} on the ordered moment Ms from NDI measurements on inhomogeneous samples containing regions with

  3. Methods for teaching effective patient communication techniques to radiography students.

    Makely, S

    1990-07-01

    Teaching students to communicate effectively with patients has always been part of the radiography curriculum in the USA. However, developing these skills has become even more important in recent times due to several factors. Patients who have been well versed in what to expect from the examination being conducted are in a better position to co-operate with the radiographer. This increases the chances of producing optimal results from an examination at the first attempt, thus reducing radiation exposure, patient discomfort and the overall cost of conducting the procedure. Also, increased competition among health care providers has resulted in more emphasis being placed on patient, or customer, satisfaction. Radiographers are in the 'front line' of patient care. Patients often have more interaction with radiographers than with physicians or other medical specialists. Radiographers who practise effective communication techniques with their patients can alleviate anxiety and make an important contribution to the overall satisfaction of the patient with respect to the quality of service and care they receive. This article describes instructional methods being used in the USA to help develop effective patient communication techniques, and reports the findings of a study among radiography educators as to which of these methods are thought to be most successful.

    1984-01-01

    Initial clinical experience in digital chest radiography utilizing photostimulable phosphor and scanning laser stimulated luminescence was reported. Image quality of conventional film/screen radiography and digital radiography was compared in 30 normal cases. Reflecting wide dynamic range of the system, improved image quality was confirmed in all 30 cases, particularly in visibility of various mediastinal structures and pulmonary vessels. High sensor sensitivity of the system enabled digital radiography to reduce radiation dose requirement significantly. Diagnostically acceptable chest images were obtained with approximately 1/5 of routine dose for conventional radiography without significant image quality degradation. Some artifact created by digital processing were mostly overcome by a routine use of simultaneous display of two different types of image processing and therefore was not an actual drawback from diagnostic standpoint. Further technical advancement of the system to be seen for digital storage, retrieval and tranceference of images. (author)

  11. The Obligation to Provide Free Basic Education in South Africa: An International Law Perspective

    Directory of Open Access Journals (Sweden)

    L Arendse

    2011-10-01

    Full Text Available In South Africa many learners are denied the right to basic education because of the levying of school fees and other educational charges, in spite of the international obligation imposed on government to provide free primary education. This article examines the exact nature and extent of this obligation by exploring the concept of "free" basic education. The applicable international instruments and their interpretation as well as the significance of the right to education as a central, facilitative right are examined in order to establish the content of the right to basic education and the legal obligations that ensue. Against this background, the implications of the South African Constitutional Court's approach to the realisation of socio-economic rights and the possibility of the establishment of a core minimum obligation are analysed. It is argued that learners in South Africa may come from different socio-economic backgrounds but as learners in the same public school domain and as equal bearers of their constitutional right to basic education all of them are entitled to the same type and quality of free basic education.

    Medical providers are trained to investigate, diagnose, and treat cancer. Their primary goal is to maximize the chances of curing the patient, with less training provided on palliative care concepts and the unique developmental needs inherent in this population. Early, systematic integration of palliative care into standard oncology practice represents a valuable, imperative approach to improving the overall cancer experience for adolescents and young adults (AYAs). The importance of competent, confident, and compassionate providers for AYAs warrants the development of effective educational strategies for teaching AYA palliative care. Just as palliative care should be integrated early in the disease trajectory of AYA patients, palliative care training should be integrated early in professional development of trainees. As the AYA age spectrum represents sequential transitions through developmental stages, trainees experience changes in their learning needs during their progression through sequential phases of training. This article reviews unique epidemiologic, developmental, and psychosocial factors that make the provision of palliative care especially challenging in AYAs. A conceptual framework is provided for AYA palliative care education. Critical instructional strategies including experiential learning, group didactic opportunity, shared learning among care disciplines, bereaved family members as educators, and online learning are reviewed. Educational issues for provider training are addressed from the perspective of the trainer, trainee, and AYA. Goals and objectives for an AYA palliative care cancer rotation are presented. Guidance is also provided on ways to support an AYA's quality of life as end of life nears.

    Despite caring for large numbers of older adults, prehospital emergency medical services (EMS) providers receive minimal geriatrics-specific training while obtaining their certification. Studies have shown that they desire further training to improve their comfort level and knowledge in caring for older adults, but continuing education programs to address these needs must account for each EMS provider's specific needs, consider each provider's learning styles, and provide an engaging, interactive experience. A novel, Internet-based, video podcast-based geriatric continuing education program was developed and implemented for EMS providers, and their perceived value of the program was evaluated. They found this resource to be highly valuable and were strongly supportive of the modality and the specific training provided. Some reported technical challenges and the inability to engage in a discussion to clarify topics as barriers. It was felt that both of these barriers could be addressed through programmatic and technological revisions. This study demonstrates the proof of concept of video podcast training to address deficiencies in EMS education regarding the care of older adults, although further work is needed to demonstrate the educational effect of video podcasts on the knowledge and skills of trainees. © 2012, Copyright the Authors Journal compilation © 2012, The American Geriatrics Society.

    Context Providing students with feedback is an important component of athletic training clinical education; however, little information is known about the feedback that Approved Clinical Instructors (ACIs; now known as preceptors) currently provide to athletic training students (ATSs). Objective To characterize the feedback provided by ACIs to ATSs during clinical education experiences. Design Qualitative study. Setting One National Collegiate Athletic Association Division I athletic training facility and 1 outpatient rehabilitation clinic that were clinical sites for 1 entry-level master's degree program accredited by the Commission on Accreditation of Athletic Training Education. Patients or Other Participants A total of 4 ACIs with various experience levels and 4 second-year ATSs. Data Collection and Analysis Extensive field observations were audio recorded, transcribed, and integrated with field notes for analysis. The constant comparative approach of open, axial, and selective coding was used to inductively analyze data and develop codes and categories. Member checking, triangulation, and peer debriefing were used to promote trustworthiness of the study. Results The ACIs gave 88 feedback statements in 45 hours and 10 minutes of observation. Characteristics of feedback categories included purpose, timing, specificity, content, form, and privacy. Conclusions Feedback that ACIs provided included several components that made each feedback exchange unique. The ACIs in our study provided feedback that is supported by the literature, suggesting that ACIs are using current recommendations for providing feedback. Feedback needs to be investigated across multiple athletic training education programs to gain more understanding of certain areas of feedback, including frequency, privacy, and form. PMID:24143902

    Emergency medical services (EMS) providers may have critical knowledge gaps in pediatric care due to lack of exposure and training. There is currently little evidence to guide educators to the knowledge gaps that most need to be addressed to improve patient safety. The objective of this study was to identify educational needs of EMS providers related to pediatric care in various domains in order to inform development of curricula. The Children's Safety Initiative-EMS performed a three-phase Delphi survey on patient safety in pediatric emergencies among providers and content experts in pediatric emergency care, including physicians, nurses, and prehospital providers of all levels. Each round included questions related to educational needs of providers or the effect of training on patient safety events. We identified knowledge gaps in the following domains: case exposure, competency and knowledge, assessment and decision making, and critical thinking and proficiency. Individual knowledge gaps were ranked by portion of respondents who ranked them "highly likely" (Likert-type score 7-10 out of 10) to contribute to safety events. There were 737 respondents who were included in analysis of the first phase of the survey. Paramedics were 50.8% of respondents, EMT-basics/first responders were 22%, and physicians 11.4%. The top educational priorities identified in the final round of the survey include pediatric airway management, responder anxiety when working with children, and general pediatric skills among providers. The top three needs in decision-making include knowing when to alter plans mid-course, knowing when to perform an advanced airway, and assessing pain in children. The top 3 technical or procedural skills needs were pediatric advanced airway, neonatal resuscitation, and intravenous/intraosseous access. For neonates, specific educational needs identified included knowing appropriate vital signs and preventing hypothermia. This is the first large-scale Delphi

    2014-01-01

    A mixed methods study conducted over three phases (Phase I – scoping exercise, Phase II – questionnaire and Phase III – semi-structured interviews) aimed to explore the role and integration of the assistant practitioner (AP) practitioner in radiography from the AP perspective. Findings of the overall study are presented across a range of articles where this publication only presents the findings in relation to the training and education of APs from all three phases. Results showed the educational routes undertaken by APs in radiography during training. Training whilst working in the clinical department has highlighted a number of key issues relating to educational pathways and delivery methods. Findings showed that APs felt that more could be done to prepare the individual for clinical practice thereby increasing their confidence and facilitating role development. Results also identified a number of challenges in the training and education of APs in radiography. Clear routes of progression and career pathways are not available to APs in radiography. In conclusion the findings suggest the need for a review of existing educational programmes and future standardisation. The need exists to clarify the justifiable methods of training and differentiate between recognised educational qualifications to enable informed career development decisions by APs and their employers

    Technological change and the increasingly rapid pace of life in the United States and globally have contributed to increased levels of stress and burnout experienced by workers and their families. Although studies are available on the levels of workplace stress and burnout affecting radiographers, little to no research has been conducted to assess the stressors encountered by radiography students in the clinical environment. This study was designed to pinpoint the primary sources of stress for radiography students and to determine the most effective measures to alleviate the stress that students experience in the clinical environment. It also sought to identify the clinical activities and practices that enhance learning. A convenience sample of radiography students attending an Association of Collegiate Educators in Radiologic Technology meeting was surveyed. Students were asked to rank their greatest stressors in the clinical environment, the most desired qualities in a clinical instructor and clinical environment, and the clinical practices and activities that best enhance their learning. Descriptive statistics were used to report the results. Data were collected for 82 first-year and second-year students. Students identified 7 primary clinical stressors: fear of making a mistake/repeat, feeling unprepared/inexperienced, intimidation by staff and by instructors, difficult/critical patients, hurtful criticism, too much supervision and negative responses to questions/requests for help. Students indicated that more frequent feedback, availability of the clinical instructor and other staff, assurance that mistakes happen and the opportunity to make mistakes were clinical practices that eased stress. The majority of students cited hands-on learning and repetition as the clinical activities that most reinforced their learning. Summary Radiography students in this survey experience some of the same clinical stressors as radiographers and other allied health workers

    Numbers of dental panoramic tomographs (DPTs) and lateral cephalometric radiographs (LCRs) outweigh other radiographic examinations in 7- to 12-year-old Finns. Orthodontists and general practitioners (GPs) involved in orthodontics hold therefore the highest responsibility of the exposure of children to ionising radiation with its risks. Against this background, lack of reports on the quality of orthodontic radiography is surprising. The purpose of our study was to shed some light and draw the awareness of the orthodontic community on the subject by analyzing the quality of orthodontic radiography in Oral Healthcare Department of City of Helsinki, in the capital of Finland. We analyzed randomly selected 241 patient files with DPTs and 118 patient files with LCRs of 7- to 12-year-olds for the indications of radiography, quality of referrals, status of interpretation, and number of failed radiographs. The majority of DPTs (95%) and all LCRs had been ordered for orthodontic reasons. Of the DPTs, 60% were ordered by GPs, and of the LCRs, 64% by orthodontists. The referrals were adequate for most DPTs (78%) and LCRs (73%), orthodontists being responsible for the majority of inadequate referrals. Of the DPTs, 80% had been interpreted. Of the LCRs, 65% lacked interpretation, but 67% had been analysed cephalometrically. Failed radiographs, leading to repeated exposure, were found in 2-3%. The quality assessment revealed that orthodontic radiography may not completely fulfill the criteria of good practice. Our results stress further need of continuing education in radiation protection among both orthodontists and GPs involved in orthodontics. © The Author 2015.

    To explore diabetes nurse educators' experiences of providing care for women, with gestational diabetes mellitus, from disadvantaged backgrounds and to gather information which would assist with the development of an educational programme that would support both women and diabetes educators. Rates of gestational diabetes mellitus have increased dramatically in recent years. This is concerning as gestational diabetes mellitus is linked to poorer pregnancy outcomes including hypertension, stillbirth, and nursery admission. Poorest outcomes occur among disadvantaged women. gestational diabetes mellitus is also associated with maternal type 2 diabetes and with child obesity and type 2 diabetes among offspring. Effective self-management of gestational diabetes mellitus reduces these risks. Diabetes nurse educators provide most education and support for gestational diabetes mellitus self-management. An interpretative phenomenological analysis approach, as espoused by Smith and Osborn (Qualitative Psychology: A Practical Guide to Research Methods, 2008, Sage, London, 51), provided the framework for this study. The views of six diabetes educators were explored through in-depth interviewing. Interviews were transcribed verbatim and analysed according to steps outlined by Smith and Osborn (Qualitative Psychology: A Practical Guide to Research Methods, 2008, Sage, London, 51). Three themes emerged from the data: (1) working in a suboptimal environment, (2) working to address the difficulties and (3) looking to the future. Throughout, the diabetes nurse educators sought opportunities to connect with women in their care and to make the educational content understandable and meaningful. Low literacy among disadvantaged women has a significant impact on their understanding of gestational diabetes mellitus information. In turn, catering for women with low literacy contributes to increased workloads for diabetes nurse educators, making them vulnerable to burnout. There is a need

Chronic disease management has been discussed as a way to improve health outcomes, with quality patient education being a key component. Using a community based participatory research framework, this study utilized a web-based survey and explored clinical staff perceptions of barriers to providing patient education during primary care visits. With a response rate of nearly 42 %, appointment time allotment seemed to be one of the most critical factors related to the delivery of health education and should be considered key. The importance of team-based care and staff training were also significant. Various suggestions were made in order to improve the delivery of quality patient education at community health centers located in underserved areas.

    Aim and method: Specialism is relative comparing the unusual to a norm. Origins of radiographers' perceptions of what is a specialism are identified. Semi-structured interviews were conducted with 21 practitioners and 10 leading voices whose combined practice span 1932-2001. Findings: Findings show that the exclusive nature of practice is influential on what is perceived as a specialism. Radiographers held career aspirations that included greater recognition, clinical involvement, autonomy and challenging work. Career aspirations were clinical rather than managerial and extended across modality boundaries. A key barrier to career progression was inequality of opportunity as local medical career requirements were dominant. Characteristics of specialism of diagnostic radiography are identified. Factors influencing the formation of specialism are also identified. Summary: Specialisation was dominant but not necessarily constructive to career progression or additional autonomy. Specialism relates to new areas of practice and is facilitated by service need, clear practice boundaries, visionary management, medical support, role development leading to increased autonomy and additional training and education.

    Perinatal depression is the most common mental illness experienced by pregnant and postpartum women, yet it is often under-detected and under-treated. Some researchers suggest this may be partly influenced by a lack of education and professional development on perinatal depression among health-care providers, which can negatively affect care and contribute to stigmatization of women experiencing altered mood. Therefore, the aim of this systematic review is to provide a synthesis of educational and professional development needs and strategies for health-care providers in perinatal depression. A systematic search of the literature was conducted in seven academic health databases using selected keywords. The search was limited to primary studies and reviews published in English between January 2006 and May/June 2015, with a focus on perinatal depression education and professional development for health-care providers. Studies were screened for inclusion by two reviewers and tie-broken by a third. Studies that met inclusion criteria were quality appraised and data extracted. Results from the studies are reported through narrative synthesis. Two thousand one hundred five studies were returned from the search, with 1790 remaining after duplicate removal. Ultimately, 12 studies of moderate and weak quality met inclusion criteria. The studies encompassed quantitative (n = 11) and qualitative (n = 1) designs, none of which were reviews, and addressed educational needs identified by health-care providers (n = 5) and strategies for professional development in perinatal mental health (n = 7). Consistently, providers identified a lack of formal education in perinatal mental health and the need for further professional development. Although the professional development interventions were diverse, the majority focused on promoting identification of perinatal depression and demonstrated modest effectiveness in improving various outcomes. This systematic review reveals a

    Digital radiography, already in use in many industrial applications, appears as a potential alternative technique to conventional radiography in the nuclear field (and more especially to the inspection of welded joints). The advantages of digital radiography are a reduced explosion risk (due to the use of lower energy and activity sources), a lower installation time, a reduced exclusion zone, and the absence of effluents. However, to the contrary of the US case, this technique may not be used in France as it is not referenced in the regulating codes (RCCM, etc.). Areva has launched a R and D study in order to characterize the equivalencies between digital and conventional radiography. First results of this study are given

    Purpose The purpose of this article is to describe the 4 Parent Education Through Simulation-Diabetes (PETS-D) nurse certified diabetes educators' (CDEs) perspectives of teaching parents of children with newly diagnosed type 1 diabetes mellitus (T1DM) early diabetes management skills using formal vignettes and a human patient simulator/human patient simulation (HPS) to augment/enhance the teaching-learning process. Methods A qualitative descriptive approach was used. Four CDEs were interviewed by phone about their teaching experiences. Meticulous notes were taken. Data were analyzed using qualitative content analysis. Results The vignettes (and use of HPS) provided structure, especially for parents who were struggling to learn. Certified diabetes educators described a short learning curve to master the use of the HPS manikin. Human patient simulation-enhanced education was described as helpful for teaching multiple caregivers about diabetes. Certified diabetes educators also described factors that affect parent learning, mechanical issues with the HPS, and additional space requirements for HPS-enhanced education. Conclusion Vignettes and HPS-enhanced education can successfully be used to educate parents of children with new-onset T1DM and were preferred by the CDEs when compared with previous teaching strategies. The results of this study support the use of both vignette-based and HPS-enhanced education when a child is newly diagnosed with T1DM. Further studies need to be done to see if these effects persist with different populations, during different stages of the disease, and for individuals with other chronic illnesses.

    Lack of familiarity with proper medication disposal options among patients can lead to personal and environmental safety concerns, besides signalling non-adherence. Given that community pharmacists are in a position to educate patients, this study assessed community pharmacists' knowledge on medication disposal and examined the utility of the theory of planned behaviour (TPB) in predicting their intention to provide medication disposal education to their patients. A cross-sectional, self-administered survey was distributed to community pharmacists in California. Descriptive statistics were reported for all survey items. Cronbach's alpha and Pearson correlation were used to determine the reliability for the four TPB constructs (attitude, subjective norm, perceived behavioural control and intention). Multiple linear regressions were performed to predict intent using the other three TPB constructs. Pharmacists (n = 142) demonstrated a positive intention to provide education (mean = 5.91 ± 1.22; range: 2 to 8), but most (67.9%) provided this information once a month or less. Attitude (β = 0.266, P = 0.001), subjective norm (β = 0.333, P behavioural control (β = 0.211, P = 0.009) were significant predictors of intention, accounting for 40.8% of the variance in intention to provide disposal education. Scale reliability ranged from 0.596 to 0.619 for the four constructs. Few pharmacists accurately selected all of the appropriate recommendations of disposal for non-controlled and controlled substances (15.9% and 10.1%, respectively). Pharmacists showed favourable attitude, subjective norm, perceived behaviour control and intention in providing such education. However, their knowledge in this area may be lacking and they are not consistently providing this information to their patients. © 2016 John Wiley & Sons, Ltd.

    Shielding calculations for neutron radiography facility, proposed to be established around PARR have been carried out using two group diffusion theory and shielding formulae. Gamma radiation penetration calculations have been carried out using simple attenuation methods. The fabrication and installation of the neutron radiography facility would provide the basis for designing a better collimating system and would help establish under water radiography facility for the inspection of highly radioactive materials and components etc. (orig./A.B.)

    If one object placed in the field under the sun, we can see the shadow of that object in two dimensional where that object was placed. Nevertheless, the sun cannot penetrate deeply so that it will produce the shadow with same object. This principal also same as radiography, however, with ionizing radiation, it can penetrate through the object so that the image that produced not only the shadow of the object but also what are inside the object. So this can give advantages for the radiographer to make inspection what are inside this object. The images that produce depend with the shape, density, thickness and distance between the object, film and source. The reader also will introduce with some term such as Distance source to film, distance source to object, and distance object to film also some basic on DIN standard and API 1104 Standard.

    An improved combination of photosensitive materials suitable for use in radiography is described, with particular reference to a combination for an X-ray intensifying screen of the fluorescent type and a silver halide recorder. The intensifying material comprises a phosphor consisting wholly or mainly of a rare earth metal activated lanthanum oxyhalide, having more than half its spectral energy emission > 410 nm wavelength, more than half its visible light spectral energy emission in the range 400 to 500 nm, and its maximum energy emission peak in the range 400 to 450 nm. The phosphor should have a coverage of at least 200 to 800 g of the oxyhalide per sq. m. The screen material also contains a dye or pigment that absorbs light within the emission spectrum of the phosphor. The photosensitive recording material incorporates at least one silver halide emulsion layer. The combination should give a screen intensification factor of at least 20 to 40 kV. (U.K.)

    Childcare services provide ideal settings to promote good oral health and help reduce tooth decay in young children. This paper reports the results of an evaluation of the dental information session component of the NSW Little Smiles Program provided by public oral health service professionals to childcare educators in NSW in 2010-2011. The evaluation sought to determine if a face-to-face information session provided to childcare educators by oral health professionals: (i) can improve the confidence of childcare educators to reach national quality standards that relate to oral health; and (ii) is an appropriate model to use. In 2010-2011, 163 dental information sessions were provided to 1716 participants from over 526 childcare centres across NSW. Results showed that a dental information session can improve the confidence of childcare educators to assist their service to reach the required national quality standards for oral hygiene and diet-related oral health issues. Further evaluation is required to determine if oral health can be embedded in the daily practice of childcare services and other options need to be explored to deliver the sessions in a more cost-effective way.

    1999-01-01

    Only two organizations are actively producing standards which are used in neutron radiology (NR): the American Society of Testing and Materials (ASTM) and the International Organization for Standardization (ISO). Six ASTM standards exist that address the neutron radiography method. Two of the ASTM standards have been extensively used world-wide. ISO has a working group which is developing three standards that also address the neutron radiography method. Two of these are currently making their way through the ISO approval system. No ASTM or ISO standards exist for the neutron radioscopic method. Future ASTM standards will address the neutron radioscopic method and neutron radiologic system characterization. It is expected that similar efforts will be undertaken in ISO. Given the relatively small community providing neutron radiologic services, international cooperation and the need for ISO standards will most likely continue to grow.(author)

    With the majority of US children enrolled in some form of early care and education, the settings for early care and education represent a valuable opportunity to positively impact young children's diets and their interactions with food. Little evidence exists on how early care and education providers make food purchasing and service decisions for this population of young children. Our aim was to explore the factors that influence early care and education providers' food purchasing and service decisions. A qualitative design consisting of individual, in-person, and semi-structured interviews with providers and on-site observations was used. Sixteen early care and education providers-selected across a variety of characteristics that might affect food selection (eg, size of site, participation in reimbursement programs, presence of staff assigned to foodservice) using maximum variation purposive sampling-based in the Puget Sound region, Washington, were interviewed from June to September 2014. Provider perspectives on food purchasing and service decisions. Inductive analysis of transcribed interviews using TAMS Analyzer software (GPL version 2, 2012) to identify themes. Ten main influencers emerged from the data. These were grouped into four categories based on an ecological framework: macro-level environments (ie, regulations; suppliers and vendors, including stores); physical environment and settings (ie, organizational mission, budget, and structure; the facility itself); social environments (ie, professional networks; peers; the site-specific parent and child community); and individual factors at both a provider and child-level (ie, providers' skills, behaviors, motivations, attitudes, knowledge, and values; child food preferences; and, child allergies). A model was then developed to identify potential pathways of intervention and underscore the need for a comprehensive approach to improve early care and education nutrition. This study suggests that a more

    Full Text Available The Michigan Department of Health and Human Services implemented and evaluated two initiatives designed to enhance provider knowledge of patients appropriate for breast and/or ovarian cancer genetic risk assessment and hereditary breast and ovarian cancer (HBOC syndrome testing. The first initiative targeted select providers who had diagnosed patients meeting HBOC risk criteria. Specifically, the initiative used 2008–2009 state cancer registry data to identify all providers who had diagnosed breast cancers in women ≤50 years of age, male breast cancers, and ovarian cancers in four health systems with newly established cancer genetics clinics. Using a method coined bidirectional reporting (BDR, reports highlighting how many of these cases each provider had seen were generated and mailed. Reports on 475 cancers (9.5% of the 5005 cases statewide meeting criteria were sent to 69 providers with information about how and why to refer such patients for genetic counseling. Providers who received a report were contacted to assess whether the reports increased awareness or resulted in action (genetic counseling/referral. Based on the few responses received, despite multiple attempts to contact, and attrition rate, it is not possible to ascertain the impact of this initiative on providers. However the project resulted in the MDHHS identifying which providers see the largest proportion of at-risk patients, creating an opportunity to target those providers with HBOC education efforts. The second initiative involved creating and broadly disseminating an online, interactive case-based educational module to increase awareness and referral decisions for HBOC using high- and low-risk patient scenarios. A total of 1835 unique users accessed the module in a one year. Collectively the users viewed topic pages 2724 times and the interactive case studies 1369 times.

    Full Text Available This study aims to give a deeper understanding on emerging business models in the context of education. Industry 4.0/the Industrial Internet in general and especially recent advances in cloud computing enable a new kind of service offering in the education sector and lead to new business models for education: Education-as-a-Service (EaaS. Within EaaS, learning, and teaching contents are delivered as services. By combining a literature review with a qualitative case study, this paper makes a three-fold contribution to the field of business models in education: First, we provide a theoretical definition for a common understanding of EaaS. Second, we present the state-of-the-art research on this new paradigm. Third, in the case study we describe a “best practices” business model of an existing EaaS provider. These insights build a theoretical foundation for further research in this area. The paper concludes with a research agenda for further research in this emerging field.

    Studies have reported that thoracic CT may provide greater sensitivity compared with radiography in detection of pediatric rib fractures and fracture healing. The additional sensitivity afforded by thoracic CT may have medicolegal implications where abuse is suspected. To determine the additional value of postmortem thoracic CT compared with radiography in detecting pediatric rib fractures, and fracture healing, using autopsy findings as a gold standard. We retrospectively reviewed 56 coroner's cases with postmortem radiography and CT thoracic survey. All studies underwent primary interpretation by one or two radiologists. The study radiologist independently reviewed all images from 13 patients with positive findings on radiography, CT or autopsy. Sensitivity and specificity between observers and imaging modalities were compared. Primary interpretation: Fractures were recognized on radiography in 5/12 patients who had fractures found at autopsy, and on CT in 8/12 patients. In total, 29% (24/83) of fractures were reported on radiography, and 51% (52/101) of fractures were reported on CT. Study radiologist: Fractures were recognized on radiography in 7/12 patients who had fractures found at autopsy, and on CT in 11/12 patients. In total, 46% (38/83) of fractures were reported on radiography, and 85% (86/101) of fractures were reported on CT. Postmortem thoracic CT provides greater sensitivity than radiography in detecting pediatric rib fractures, most notably in anterior and posterior fractures. However, the degree of improvement in sensitivity provided by CT might depend on observer experience. (orig.)

    Diagnostic imaging has evolved from single technique to a field which we have a choice from many modalities. Some without radiation. Radiation producing modalities include plain films (low dose), Fluoroscopy (mid range dose), Computed tomography (high dose). Radiography dose can significantly be influenced in plain radiography by varying speed of screens, cassette construction and type of radiography. E.g. digital or computed. In computed or digital radiography we are no longer able to tell h igh dose b y the quality of images. The final image is by great extend a product of post processing algorithms. It's for this reasons that the basic understanding of the sensitivity and specifying of various types of examinations and of specifically radiation effects is mandatory for a paediatric imager

    The purpose of this study was to assess radiographer familiarity and preferences with digital radiography in four teaching hospitals and thereafter make recommendations in line with the migration from screen film to digital radiography. A questionnaire was designed to collect data from either qualified or student radiographers from four teaching hospitals. From the four teaching hospitals, there were a total of 205 potential respondents. Among other things, responses regarding experiences and preferences with digital radiography, quality control procedures, patient dose, advantages and disadvantages of digital radiography were sought. The information collected was based on self-reporting by the participants. The study is exploratory in nature and descriptive statistics were generated from the collected data using Microsoft Excel 2007 and StatsDirect software. Sixty-three out of 205 (31%) radiographers from all the four radiology centers responded to the circulated questionnaire. Only 15% (8) of the qualified radiographers had 4 or more years of experience with digital radiography compared to 68% (36) for the same amount of experience with screen-film radiography. Sixty-one percent (38) of the participants had been exposed to digital radiography during their lectures while at university. A small proportion, 16% (10) of the respondents underwent formal training in quality control procedures on the digital X-ray units they were using. Slightly more than half (55%) of the participants felt it was easier for them to retake an image in digital radiography than in screen film radiography. The results of this survey showed that the participants are familiar with digital radiography and have embraced this relatively new technology as shown by the fact that they can identify both its advantages and disadvantages as applied to clinical practice. However, there are minimal quality control procedures specific to digital radiography being undertaken as such there is need for

    Full Text Available Objective: To evaluate the impact pharmacist-provided screening and education had on patient knowledge of osteoporosis and preventive strategies. Methods: A prospective, randomized, controlled study was conducted at 16 locations of a national supermarket chain pharmacy in the Richmond, Virginia area. Women 30 years and older with no history of osteoporosis were enrolled in the study. Patients self-selected into the study by agreeing to the bone density screening, pharmacist-provided education, and completion of a knowledge survey. Subjects were randomized to complete the osteoporosis-related knowledge survey either before (Group A or after (Group B the screening and education session. The survey was developed after guideline and literature evaluation and was pretested with a group of patients for content and clarity. The survey evaluated knowledge of osteoporosis, risk factors for the disease, appropriate age for testing, and preventive strategies. Groups A and B were compared using t-tests. Results: A total of 110 women were enrolled in the study. The mean (±SD age was 52.5 ± 13.1 years in Group A (n=52 and 52.7 ± 11.5 years in Group B (n=58. Knowledge scores were higher in the group who received pharmacist-provided education prior to completing the survey in each category (knowledge of the disease, risk factors, preventive strategies, and appropriate age for testing and overall (p<0.001. Conclusions: Community pharmacist-provided osteoporosis screening and education increased patient knowledge about osteoporosis and preventive strategies.

    We evaluated the effects of abbreviated (i.e., one-session) video modeling on delivery of student-preferred attention by educational care-providers. The video depicted a novel care-provider interacting with and delivering attention to the student. Within a concurrent multiple baseline design, video modeling increased delivery of the targeted attention for all participants as well as their delivery of another type of attention that was not trained although these effects were variable within and between care-providers. We discuss the clinical and training implications from these findings.

Simulation is an effective pedagogy to bring students from multiple professions together for learning. This article describes a pilot study where nursing and social work students learned together in a simulated learning activity, which was evaluated to by the Readiness for Interprofessional Learning Scale (RIPLS). The RIPLS was used before and after the simulated activity to determine if this form of education impacted students' perceptions of readiness to learn together. Students from both professions improved in their RIPLS scores. Students were also asked to identify their interprofessional strengths and challenges before and after the simulation. Changes were identified in qualitative data where reports of strengths and challenges indicated learning and growth had occurred. In conclusion, this pilot study suggests that interprofessional simulation can be an effective method to integrate Interprofessional Education Collaborative core competencies into the curriculum.

    Mental health system transformation toward a recovery-orientation has created a demand for education to equip providers with recovery competencies. This report describes the development of a recovery education program designed specifically for inpatient providers. Part 1 of the education is a self-learning program introducing recovery concepts and a recovery competency framework; Part 2 is a group-learning program focusing on real-life dilemmas and applying the Appreciative Inquiry approach to address these clinical dilemmas. A pilot study with a pretest/posttest design was used to evaluate the program. Participants included 26 inpatient multidisciplinary providers from 3 hospitals. The results showed participants' improvement on recovery knowledge (z = -2.55, p = .011) after the self-learning program. Evaluations of the group-learning program were high (4.21 out of 5). These results support continued efforts to refine the program. Inpatient providers could use this program to lead interprofessional practice in promoting recovery. (c) 2014 APA, all rights reserved.

    To assess the readability of online education materials offered by hospitals describing commonly performed interventional radiology (IR) procedures. Online patient education materials from 402 hospitals selected from the Medicare Hospital Compare database were assessed. The presence of an IR service was determined by representation in the Society of Interventional Radiology physician finder directory. Patient online education materials about (i) uterine artery embolization for fibroid tumors, (ii) liver cancer embolization, (iii) varicose vein treatment, (iv) central venous access, (v) inferior vena cava (IVC) filter placement, (vi) nephrostomy tube insertion, (vii) gastrostomy tube placement, and (viii) vertebral augmentation were targeted and assessed by using six validated readability scoring systems. Of 402 hospitals sampled, 156 (39%) were presumed to offer IR services. Of these, 119 (76%) offered online patient education material for one or more of the eight service lines. The average readability scores corresponding to grade varied between the ninth- and 12th-grade levels. All were higher than the recommended seventh-grade level (P Reading Ease scores ranged from 42 to 69, corresponding with fairly difficult to difficult readability for all service lines except IVC filter and gastrostomy tube placement, which corresponded with standard readability. A majority of hospitals offering IR services provide at least some online patient education material. Most, however, are written significantly above the reading comprehension level of most Americans. More attention to health literacy by hospitals and IR physicians is warranted. Copyright © 2015 SIR. Published by Elsevier Inc. All rights reserved.

    Because no effective methods for preventing or screening for ovarian cancer exist, symptom recognition is integral to its early detection. The Centers for Disease Control and Prevention's Inside Knowledge: Get the Facts about Gynecologic Cancer campaign was developed to raise awareness and educate women and providers about risk factors, symptoms, recommended screening, and prevention strategies for the five main gynecologic cancers, including ovarian cancer. Inside Knowledge campaign materials were utilized by CDC's National Comprehensive Cancer Control Program grantees to educate women and providers about gynecologic cancer from 2014 to 2015. Grantees recruited participants and held educational sessions using Inside Knowledge materials. Questionnaires were given before and after the sessions to assess changes in awareness, confidence, and behavioral intentions around gynecologic cancer information and analyzed in 2016. This analysis focused on an assessment of changes related to ovarian cancer information. Participants' knowledge increased after educational sessions. Among women, there were increases in correctly identifying that the Papanicolaou (Pap) test does not screen for ovarian cancer (89.2%) and that genetic testing is available (77.9%). There was a lower increase in knowledge that HPV is not a cause of ovarian cancer (56.4%). Providers and women reported significant increases in their confidence in their ability to talk to each other about gynecologic cancer post-session. Ovarian cancer awareness, confidence, and related behaviors increased in participants exposed to Inside Knowledge materials. Using these materials to increase knowledge could lead to more empowered patients, better provider-patient communications, and improved care for gynecologic cancers, including ovarian cancer.

  18. Analysis of the spatial rates dose rates during dental panoramic radiography

    A dental panoramic radiography which usually uses low level X-rays is subject to the Nuclear Safety Act when it is installed for the purpose of education. This paper measures radiation dose and spatial dose rate by usage and thereby aims to verify the effectiveness of radiation safety equipment and provide basic information for radiation safety of radiation workers and students. After glass dosimeter (GD-352M) is attached to direct exposure area, the teeth, and indirect exposure area, the eye lens and the thyroid, on the dental radiography head phantom, these exposure areas are measured. Then, after dividing the horizontal into a 45°, it is separated into seven directions which all includes 30, 60, 90, 120 cm distance. The paper shows that the spatial dose rate is the highest at 30 cm and declines as the distance increases. At 30 cm, the spatial dose rate around the starting area of rotation is 3,840 μSv/h, which is four times higher than the lowest level 778 μSv/h. Furthermore, the spatial dose rate was 408 μSv/h on average at the distance of 60 cm where radiation workers can be located. From a conservative point of view, It is possible to avoid needless exposure to radiation for the purpose of education. However, in case that an unintended exposure to radiation happens within a radiation controlled area, it is still necessary to educate radiation safety. But according to the current Medical Service Act, in medical institutions, even if they are not installed, the equipment such as interlock are obliged by the Nuclear Safety Law, considering that the spatial dose rate of the educational dental panoramic radiography room is low. It seems to be excessive regulation.

  19. Digital luminescent radiography: A substitute for conventional chest radiography?

    The image quality of digital luminescent radiography (DLR) is sufficient for routine biplane chest radiography and for follow-up studies of heart size, pulmonary congestion, coin lesions, infiltrations, atelectasis, pleural effusions, and mediastinal and hilar lymph node enlargement. Chest radiography in the intensive care unit may in most cases be performed using the DLR technique. there is no need for repeat shots because of incorrect exposure, and the position of catheters, tubes, pacemakers, drains and artificial heart valves, the mediastinum, and the retrocardiac areas of the left lung are more confidently assessed on the edge-enhanced DLR films than on conventional films. Nevertheless, DLR is somewhat inferior to conventional film-screen radiography of the chest as it can demonstrate or rule out subtle pulmonary interstitial disease less confidently. There is no reduction of radiation exposure of the chest in DLR compared with modern film-screen systems. As a consequence, DLR is presently not in a position to replace traditional film-screen radiography of the chest completely. (orig.) [de

    High energy, heavy-ion beams offer superior discrimination of tissue electron densities at very low radiation doses. This characteristic has potential for diagnostic medical imaging of neoplasms arising in the soft tissues and organs because it can detect smaller inhomogeneities than x rays. Heavy-ion imaging may also increase the accuracy of cancer radiotherapy planning involving use of accelerated charged particles. In the current physics research program of passive heavy-ion imaging, critical modulation transfer function tests are being carried out in heavy-ion projection radiography and heavy-ion computerized tomography. The research goal is to improve the heavy-ion imaging method until it reaches the limits of its theoretical resolution defined by range straggling, multiple scattering, and other factors involved in the beam quality characteristics. Clinical uses of the imaging method include the application of heavy-ion computerized tomography to heavy-ion radiotherapy planning, to the study of brain tumors and other structures of the head, and to low-dose heavy-ion projection mammography, particularly for women with dense breasts where other methods of diagnosis fail. The ions used are primarily 300 to 570 MeV/amu carbon and neon ions accelerated at the Lawrence Berkeley Laboratory Bevalac

    To explore the health education needs and learning preferences of female intimate partner violence (IPV) survivors in a social service agency located in South Florida, United States. An exploratory two-phase sequential mixed-methods study was completed through semistructured interviews with social service providers (n = 10), followed by a survey with predominately female IPV survivors (n = 122, 98.4%). Data obtained from interviews with social service providers were analyzed through conventional thematic content analysis. Data from interviews were used in developing a health survey completed by IPV survivors and analyzed utilizing descriptive statistics, chi-square tests and t tests. Three themes emerged from interviews including multidimensional health needs, navigating barriers to health care, and self-improvement specific to survivors of intimate partner violence. Survey results indicated that depression and self-esteem were the health education needs of highest priority. Demographic characteristics, including age and language use, were significantly associated to preferred methods of learning, p education needs. Current study findings can inform public health nurses in developing interventions or health-based programs for female IPV survivors in social service agency settings. © 2017 Wiley Periodicals, Inc.

    Distance education is a solution to expand medical imaging education to students who might not otherwise be able to obtain the education. It can be a mechanism to reduce the health care worker shortage in underserved areas. In some cases, distance education may be a disruptive technology, and might lower student performance. This study compares student scores in a cadaver anatomy course in the four cohorts preceding the implementation of distance education to the first three cohorts that took the course using a multiple campus design. The means and medians of the lecture exam average, the laboratory component score, and the final course score of the nondistance education cohorts were compared with those of the distance education cohorts using nonparametric statistical analysis. Scores in an anatomy course were compared by campus placement among the distance education cohorts, and the independent effect of distance education on the laboratory component, lecture examination average, and final course scores, while controlling for cumulative grade point average and site (originating/distant), was assessed. Students receiving the course in a nondistance education environment scored higher in the anatomy course than the students who took the course in a distance education environment. Students on the distant campus scored lower than students on the originating site. Distance education technology creates new opportunities for learning, but can be a disruptive technology. Programs seeking to implement distance education into their curriculum should do so with knowledge of the advantages and disadvantages.

  5. Computed radiography in NDT application

    Deprins, Eric

    2004-01-01

    Computed Radiography, or digital radiography by use of reusable Storage Phosphor screens, offers a convenient and reliable way to replace film. In addition to the reduced cost on consumables, the return on investment of CR systems is strongly determined by savings in exposure time, processing times and archival times. But also intangible costs like plant shutdown, environment safety and longer usability of isotopes are increasingly important when considering replacing film by Storage Phosphor systems. But mote than in traditional radiography, the use of digital images is a trade-off between the speed and the required quality. Better image quality is obtained by longer exposure times, slower phosphor screens and higher scan resolutions. Therefore, different kinds of storage phosphor screens are needed in order to cover every application. Most operations have the data, associated with the tests to be performed, centrally stored in a database. Using a digital radiography system gives not only the advantages of the manipulation of digital images, but also the digital data that is associated with it. Smart methods to associate cassettes and Storage screens with exposed images enhance the workflow of the NDT processes, and avoid human error. Automated measurements tools increase the throughput in different kinds of operations. This paper gives an overview of the way certain operations have decided to replace film by Computed Radiography, and what the major benefits for them have been.

    Its nearly one year and a half since digital imaging/radiography was introduced in Kenya mainly in Nairobi. the technology is becoming an increasingly effective and acceptable modality of producing radiographs from the traditional conventional radiography in use to date. the digital radiography offers numerous advantages that have been noted for the short period over the conventional way. For instance radiographs are produced in real time (less than 3 minutes), by so doing the technology has eliminated the wait for the processing period. the radiation exposure to the patient under the radiological examination is reduced as much as 90% from the traditional conventional film taking. The cost, labour and record-keeping necessary to maintain a chemical processor and darkroom operations are as well eliminated. The cost of purchasing and disposing of film wastes/darkroom processing chemicals, which are environmentally hazardous, also become unnecessary.digital radiography technology makes the digital images comparable to other images on the screen at that instant making both the patient and the clinician easily access images when needed. digital receptors have also replaced the cassette containing intensifying screens and film that is used in conventional radiography

  7. Computed radiography for breast cancer

    1990-01-01

    In order to evaluate the possibility of using computed radiographic mammography in mass surveys of the breast, we have retrospectively examined 71 breast cancer lesions in 71 patients using computed radiographic and conventional non-screen mammographies and have carried out comparative studies on tumor detection rate and calcification. A 95.8% detection rate was obtained for the tumor image (n 71) using computed radiography (CR) and one of 93.0% using non-screen techniques. Three lesions remained undetected by either study. A 100% detection rate was obtained for calcification associated with cancer (n 33) from each method. No significant differences in either detection rate or calcification were seen between the two images. On the other hand, the ability to recognize tumor images (n 66) was as follows; CR superior to non-screen radiography in 53 lesions (80.3%), equal in eight lesions (12.1%) and inferior in five lesions (7.6%). For the calcification images (n 18), CR was superior to non-screen radiography in all 18 lesions. Obviously, CR gives better results than non-screen radiography. Furthermore, an adequate image can be obtained using CR even although the X-ray dosage is only a twentieth of that required for non-screen radiography. It can therefore be applied not only to mass surveys for breast cancer but also to routine clinical diagnoses. (author)

    In order to integrate current scientific discoveries in the classroom, K-12 teachers benefit from professional development and support. The Lunar Workshops for Educators is a series of weeklong workshops for grade 6-9 science teachers focused on lunar science and exploration, sponsored by the Lunar Reconnaissance Orbiter (LRO) and conducted by the LRO Education and Public Outreach (E/PO) Team. The Lunar Workshops for Educators, have provided this professional development for teachers for the last five years. Program evaluation includes pre- and post- content tests and surveys related to classroom practice, daily surveys, and follow-up surveys conducted during the academic year following the summer workshops to assess how the knowledge and skills learned at the workshop are being used in the classroom. The evaluation of the workshop shows that the participants increased their overall knowledge of lunar science and exploration. Additionally, they gained knowledge about student misconceptions related to the Moon and ways to address those misconceptions. The workshops impacted the ways teachers taught about the Moon by providing them with resources to teach about the Moon and increased confidence in teaching about these topics. Participants reported ways that the workshop impacted their teaching practices beyond teaching about the Moon, encouraging them to include more inquiry and other teaching techniques demonstrated in the workshops in their science classes. Overall, the program evaluation has shown the Lunar Workshops for Educators are effective at increasing teachers’ knowledge about the Moon and use of inquiry-based teaching into their classrooms. Additionally, the program supports participant teachers in integrating current scientific discoveries into their classrooms.

    We performed an environmental scan of currently available websites providing educational information about rheumatoid arthritis (RA) and evaluated the quality of these websites. We searched three separate search engines, Google, Bing, and Ask.com, on August 27, 2015, using two search terms, "arthritis" and "rheumatoid." Only patient education websites were included. Two independent investigators evaluated the accuracy, completeness, technical elements, design and esthetics, readability, usability, and accessibility of the websites. The navigation experience was also evaluated by an adult training expert. We identified 46 websites. Nearly all websites (98%) provided accurate information. However, no website covered all essential RA topics. Common essential topics not covered included epidemiology, pathogenesis, treatment and disease monitoring, complications, self-management, risks and benefits of treatment, prognosis, treatment adherence, questions for patients to ask their doctors, and costs. For the technical elements, all websites disclosed their ownership, but the date that the content was last updated was mentioned in only 10 websites, ranging from 2007 to 2015. The mean reading level was grade 12.1 (standard deviation ±2.3). Most websites (78%) were easy to navigate but only 33% were friendly for people with visual and/or hearing impairments. The navigation experience was rated fair or poor in 41% of the websites. Current patient information on the Internet does not comprehensively address all educational needs of patients with RA, and is often outdated. The findings from our study highlight potential areas for improvement in online education materials for patients with RA. Copyright © 2017. Published by Elsevier Inc.

    To assess the readability of the web-based patient education material provided by the European Association of Urology. English patient education materials (PEM) as available in May 2017 were obtained from the EAU website. Each topic was analyzed separately using six well-established readability assessment tools, including Flesch-Kincaid Grade Level (FKGL), SMOG Grade Level (SMOG), Coleman-Liau Index (CLI), Gunning Fog Index (GFI), Flesch Reading Ease Formula (FRE) and Fry Readability Graph (FRG). A total of 17 main topics were identified of which separate basic and in-depth information is provided for 14 topics. Calculation of grade levels (FKGL, SMOG, CLI, GFI) showed readability scores of 7th-13th grade for basic information, 8th-15th grade for in-depth information and 7th-15th grade for single PEM. Median FRE score was 54 points (range 45-65) for basic information and 56 points (41-64) for in-depth information. The FRG as a graphical assessment revealed only 13 valid results with an approximate 8th-17th grade level. The EAU provides carefully worked out PEM for 17 urological topics. Although improved readability compared to similar analyses was found, a simplification of certain chapters might be helpful to facilitate better patient understanding.

    Attention-deficit hyperactivity disorder (ADHD) diagnostic prevalence and medication use vary across U.S. census regions, but little is known about state-level variation. The purpose of this study was to estimate this variation across states and examine whether a state's health care provider characteristics and education policies are associated with this variation. Logistic regression models were estimated with 69,505 children aged four to 17 from the state-stratified and nationally representative 2003 National Survey of Children's Health, conducted by the Centers for Disease Control and Prevention. Diagnostic prevalence was higher in the South (odds ratio [OR]=1.42, p<.001) than in the West; among children with ADHD diagnoses, medication use was higher in the South (OR=1.60, p<.01) and the Midwest (OR=1.53, p<.01) versus the West. On these measures, several states differed from the U.S. averages, including some states that, on the basis of the regional patterns found above, would not be expected to differ: Michigan had a high diagnostic prevalence; Vermont, South Dakota, and Nebraska had low diagnostic prevalences; and Connecticut, New Jersey, and Kentucky had low medication rates. Both diagnosis and medication status were associated with the number, age, and type of physicians within a state, particularly pediatricians. However, state education policies were not significantly associated with either diagnostic prevalence or medication rates. To better understand the association between a state's health care provider characteristics and both diagnostic prevalence and medication use, it may be fruitful to examine the content of provider continuing education programs, including the recommendations of major health professional organization guidelines to treat ADHD.

    Plutonium bearing materials packaged for long term storage per the Department of Energy Standard 3013 (DOE-STD-3013) are required to be examined periodically in a non-destructive manner (i.e. without compromising the storage containers) for pressure buildup. Radiography is the preferred technology for performing the examinations. The concept is to measure and record the container lid position. As a can pressurizes the lid will deflect outward and thus provide an indication of the internal pressure. A radiograph generated within 30 days of creation of each storage container serves as the baseline from which future surveillance examinations will be compared. A problem with measuring the lid position was discovered during testing of a digital radiography system. The solution was to provide a distinct feature upon the lower surface of the container lid from which the digital radiography system could easily track the lid position

    Neutron radiography performed with a reactor source has been shown to be a superior radiographic method for the examination of unirradiated mixed oxide fuel pins at the Hanford Engineering Development Laboratory. Approximately 1,700 fuel pins were contained in a sample that demonstrated the capability of the method for detecting laminations, structural flaws, fissile density variation, hydrogenous inclusions and voids in assembled fuel pins. The nature, extent, and importance of the detected conditions are substantiated by gamma autoradiography and by destructive analysis employing alpha autoradiography, electron microprobe and visual inspection. Also, a series of radiographs illustrate the response of neutron radiography as compared to low voltage and high voltage x-ray and gamma source Iridium 192 radiography. (U.S.)

    2011-01-01

    Background/objective Persons with chronic spinal cord injury (SCI) have a high lifetime need for ongoing patient education to reduce the risk of serious and costly medical conditions. We have addressed this need through monthly in-person public education programs called SCI Forums. More recently, we began videotaping these programs for streaming on our website to reach a geographically diverse audience of patients, caregivers, and providers. Design/methods We compared information from the in-person forums to that of the same forums shown streaming on our website during a 1-year period. Results Both the in-person and Internet versions of the forums received high overall ratings from individuals who completed evaluation forms. Eighty-eight percent of online evaluators and 96% of in-person evaluators reported that they gained new information from the forum; 52 and 64% said they changed their attitude, and 61 and 68% said they would probably change their behavior or take some kind of action based on information they learned. Ninety-one percent of online evaluators reported that video is better than text for presenting this kind of information. Conclusion Online video is an accessible, effective, and well-accepted way to present ongoing SCI education and can reach a wider geographical audience than in-person presentations. PMID:21903014

    2008-01-01

    A new radiography technique to inspect thin samples was developed. Low energy alpha particles, generated by a boron based screen under thermal neutron irradiation, are used as penetrating radiation. The solid state nuclear track detector CR-39 has been used to register the image. The interaction of the α - particles with the CR-39 gives rise to damages which under an adequate chemical etching became tracks the basic units forming the image. A digital system was developed for data acquisition and data analysis as well as for image processing. The irradiation and etching conditions to obtain the best radiography are 1,3 hours and 25 minutes at 70 deg C respectively. For such conditions samples having 10 μm in thickness can be inspected with a spatial resolution of 32 μm. The use of the digital system has reduced the time spent for data acquisition and data analysis and has improved the radiography image visualization. Furthermore, by using the digital system, it was possible to study several new parameters regarding the tracks which are very important to understand and study the image formation theory in solid state nuclear track detectors, the one used in this thesis. Some radiography images are also shown which demonstrate the potential of the proposed radiography technique. When compared with the other radiography techniques already in use to inspect thin samples, the present one developed in the present paper allows a smaller time to obtain the image, it is not necessary to handle liquid radioactive substances, the detector is insensitive to β, γ, X-ray and visible light.

    To determine the relationship of determinants such as age, ethnicity, education and sexual behaviour with repeat teenage pregnancy and to determine the impact of 'Providing Access to Continued Education' (PACE) programme in reducing repeat teenage pregnancy amongst its participants in The Bahamas. This retrospective cohort study included 397 attendees of the Adolescent Health Centre (AHC). Eighty-eight out of 139 registered participants completed the PACE programme. Data on age, ethnicity, education, sexual behaviour and repeat pregnancy in two years were analysed for descriptive statistics, and association of demographic characteristics and participation in the PACE programme with repeat pregnancy using the Chi-squared test. Mean age of participants was 16.4 ± 1.1 years; median school grade and mean grade point average (GPA) was 11 and 1.97 ± 0.7, respectively. The mean age at the first sexual activity was 14.9 ± 1.2 years. The mean age and number of sexual partners were 21 ± 4.3 years and 2 ± 1, respectively. Overall, repeat pregnancy rate was 39%: 37.4% amongst PACE registered and 31.8% amongst PACE completed mothers. No significant difference was observed in repeat pregnancy between registered and non-registered as well as those who completed the programme and those who did not. The odds ratio of 0.525 suggested that completion of the PACE programme had a moderate protective effect on reducing repeat pregnancy. Age, ethnicity, education and sexual behaviour showed no association with repeat pregnancy. The PACE programme did not reduce repeat pregnancy rate significantly. However, completion of the programme offered a moderate protection.

    The majority of acute care facilities have not developed policies or guidelines to facilitate family presence during cardiopulmonary resuscitation. Prior studies have shown that the personal beliefs and attitudes of hospital personnel involved in resuscitation efforts are the primary reasons family presence is not offered. This 2-phase, before/after study was conducted in a 388-bed academic trauma center, and in a 143-bed community hospital in eastern Washington State in 2008. In phase I, a convenience sample of physicians and registered nurses from both facilities were surveyed about their opinions and beliefs regarding family-witnessed resuscitation (FWR). Spearman's rho and independent t-tests were used to compare support of FWR between and within roles and practice location subgroups. In phase II of the study, clinician subgroups in the community hospital were re-surveyed following an educational program that used evidence-based information. Independent t-test and one-way ANOVA were used to compare pre and post-education mean scores of subgroups on indicators of effective teaching strategies and improved FWR support. Opinions on FWR vary within and between practice roles and locations, with the strongest variable of support being prior experience with FWR. Following FWR education, mean scores improved for survey variables chosen as indicators of FWR support and teaching effectiveness. When CPR providers are presented with FWR education, their opinion-based beliefs may be modified, decreasing barriers to family witnessed resuscitation and improving overall support of FWR as an extension of family-centered care.

    Full Text Available Early childhood care and education providers (CCPs work with over 7 million young children. These children are vulnerable to physical, sexual and emotional abuse, and neglect. However, CCPs make less than 1% of all reports of suspected child abuse and neglect that are made to child protective services. CCPs are therefore an untapped resource in the public health response to child maltreatment. However, their knowledge and attitudes about duties to report child maltreatment are poorly understood. Moreover, no rigorous research has tested whether their knowledge and attitudes about reporting child maltreatment can be improved. These gaps in knowledge are important because knowledge of the duty and positive attitudes towards it produce more effective reporting, and little evidence exists about how to enhance cognitive and affective attributes. Using the CONSORT approach, we report a single-blind test-retest randomized controlled trial evaluating iLook Out for Child Abuse, a customized online educational intervention for CCPs to increase knowledge and attitudes towards the reporting duty. 762 participants were randomized with results analyzed for 741 participants (372 in the intervention group; 369 in the control.

    Currently, there are limited resources and training available for otolaryngologists and otolaryngology practice personnel to provide gender-affirming care for transgender or gender nonconforming patients. This unique patient population may present to our offices for gender-specific care or with complaints of the ear, nose, and throat unrelated to gender identity. Our current practice has unintentional but direct consequences on our patients care, as transgender patients often report negative experiences in the healthcare setting related to their gender identity. The absence of resources and training is also seen in other specialties. Physicians who create an environment where patients of all gender identities feel welcome can better meet their patients' health care needs. In addition, otolaryngologists can play a role in easing the gender dysphoria experienced by transgender patients. We suggest educational content should be created for and made available to otolaryngologists and office staff to provide gender-affirming care.

    Axial tomography from digitized real time radiographs provides a useful tool for industrial radiography and tomography. The components of this system are: x-ray source, image intensifier, video camera, video line extractor and digitizer, data storage and reconstruction computers. With this system it is possible to view a two dimensional x-ray image in real time at each angle of rotation and select the tomography plane of interest by choosing which video line to digitize. The digitization of a video line requires less than a second making data acquisition relatively short. Further improvements on this system are planned and initial results are reported.

    2015-11-01

    Traffic crashes are the leading cause of death among teens. Health care providers have an opportunity to address what works to keep teens safe on the road during the patient visit. An online survey was conducted of 1088 health care providers who saw patients at or near driving age. The survey assessed which road safety topics were discussed and which types of educational products were used most often. Family and general practice physicians represented 44.3% of the sample, followed by pediatricians (22.5%), nurse practitioners (17.6%), and internists (15.5%). Nearly all respondents (92.9%) reported addressing one or more driving safety factors (seat belt use, nighttime driving, fatigue, teen passengers, alcohol/drug use, speeding/reckless driving, and cell phone use/texting) with adolescent patients and/or their parents. Seat belt use was reported more often (83.7%) than other topics. The use of parent-teen driving agreements, a known effective intervention, was reported by less than 10% of respondents. Since health care providers expressed interest in receiving written resource materials, distribution of parent-teen driving agreements to health care providers might encourage greater uptake and use of this effective intervention.

    This study systematically examined child-service providers' conceptualizations of trauma-informed practice (TIP) across service systems, including child welfare, juvenile justice, mental health, and education. Eleven focus groups and nine individual interviews were conducted, totaling 126 child-service providers. Conventional content analysis was used to analyze the qualitative data with interrater reliability analyses indicating near perfect agreement between coders. Qualitative analysis revealed that child-service providers identified traumatic stress as an important common theme among children and families served as well as the interest in TIP in their service systems. At the same time, child-service providers generally felt knowledgeable about what they define TIP to be, although they articulated wide variations in the degree to which they are taught skills and strategies to respond to their traumatized clients. The results of this study suggest a need for a common lexicon and metric with which to advance TIP within and across child-service systems. © The Author(s) 2016.

    This article describes the design and performance of a magnifying magnetic-lens system designed, built, and commissioned at the Los Alamos National Laboratory (LANL) for 800 MeV flash proton radiography. The technique of flash proton radiography has been developed at LANL to study material properties under dynamic loading conditions through the analysis of time sequences of proton radiographs. The requirements of this growing experimental program have resulted in the need for improvements in spatial radiographic resolution. To meet these needs, a new magnetic lens system, consisting of four permanent magnet quadrupoles, has been developed. This new lens system was designed to reduce the second order chromatic aberrations, the dominant source of image blur in 800 MeV proton radiography, as well as magnifying the image to reduce the blur contribution from the detector and camera systems. The recently commissioned lens system performed as designed, providing nearly a factor of three improvement in radiographic resolution.

    Industrial radiography and especially gamma-radiography, has established itself as a very powerful tool in non-destructive testing. Unfortunately there is an amount of risk attached to the use of industrial radiography. The primary causes of radiography accidents include: working conditions, equipment failure and lack of supervisory control. To alleviate the radiological risks involved with gamma-radiography, the Atomic Energy Corporation (AEC) has imposed various conditions for the possession, use, and conveyance of radioactive material. This includes personnel training and equipment specifications

    Moisture and corrosion in the F-lll aluminum honeycomb structure is a significant maintenance problem for these 1960 vintage aircraft. Corrosion and moisture are not readily detectable with conventional nondestructive testing techniques such as X-ray. However, by using neutron radiography, high quality images of the corrosion and moisture within the panels can be obtained. The SNRS-1 TRIGA was developed to provide the high intensity neutron source needed to support systems that enable neutron radiography to be performed on these aircraft parts

    The Austrian Soil Science Society (ASSS), founded in 1954, is a non-profit organisation aiming at furthering all branches of soil science in Austria. The ASSS provides information on the current state of soil research in Austria and abroad. It organizes annual conferences for scientists from soil and related sciences to exchange their recent studies and offers a journal for scientific publications. Annually, ASSS awards the Kubiena Research Prize for excellent scientific studies provided by young scientists. In order to conserve and improve soil science in the field, excursions are organized, also in cooperation with other scientific organisations. Due to well-established contacts with soil scientists and soil science societies in many countries, the ASSS is able to provide its members with information about the most recent developments in the field of soil science. This contributes to a broadening of the current scientific knowledge on soils. The ASSS also co-operates in the organisation of excursions and meetings with neighbouring countries. Several members of the ASSS teach soil science at various Austrian universities. More detail on said conferences, excursions, publications and awards will be given in the presentation. Beside its own scientific journal, published once or twice a year, and special editions such as guidebooks for soil classification, the ASSS runs a website providing information on the Society, its activities, meetings, publications, awards and projects. Together with the Environment Agency Austria the ASSS runs a soil platform on the internet. It is accessible for the public and thus informs society about soil issues. This platform offers a calendar with national and international soil events, contacts of soil related organisations and networks, information on national projects and publications. The society has access to products, information material and information on educational courses. Last but not least information on specific soil

    Full Text Available Endobronchial tuberculosis and chest radiography I read, with interest, the article entitled “Clinical and Para-clinical Presentations of Endobronchial Tuberculosis” by Ahmadi Hoseini H. S. et al. (1 published in this journal. I would like to focus on some details about the chest X-ray of patients as elaborated by the authors in the results section. Accordingly, the findings of chest radiography in the available patients were as follows: pulmonary consolidation (75%, reduced pulmonary volume (20%, and hilar adenopathy (10%. This is an incomplete statement because the authors did not explain whether there was any normal chest radiography in the study population. In addition, it is not clear whether the X-ray examinations of the patients were normal, how many abnormal plain films yielded the presented data. On the other hand, the fact that the studied patients had no normal chest radiography is  controversial since in the literature, 10-20% of the patients with endobronchial tuberculosis are reported to have normal chest X-ray (2, 3. In fact, this is one of the problems in the diagnosis of the disease, as well as a potential cause of delayed diagnosis and treatment of the patients. Therefore, the absence of normal chest radiographs is in contrast to the available literature, and if not an error, it could be a subject of further investigation.

    This study aims to help nurse educators/academics understand the perspectives and expectations of students providing their feedback to educators about teaching performance and subject quality. The aim of this study is to reveal students' voices regarding their feedback in nurse education in order to shed light on how the current student feedback practice may be modified. A qualitative study using focus group inquiry. Convenience sampling was adopted and participants recruited from one school of nursing in Hong Kong. A total of 66 nursing students from two pre-registration programs were recruited for seven focus group interviews: one group of Year 1 students (n=21), two groups of Year 3 students (n=27), and four groups of Final Year students (n=18). The interviews were guided by a semi-structured interview guideline and the interview narratives were processed through content analysis. The trustworthiness of this study was guaranteed through peer checking, research meetings, and an audit trail. The participants' privacy was protected throughout the study. Four core themes were discerned based on the narratives of the focus group interviews: (1) "timing of collecting feedback at more than one time point"; (2) "modify the questions being asked in collecting student feedback"; (3) "are electronic means of collecting feedback good enough?; and (4) "what will be next for student feedback?". This study is significant in the following three domains: 1) it contributed to student feedback because it examined the issue from a student's perspective; 2) it explored the timing and channels for collecting feedback from the students' point of view; and 3) it showed the preferred uses of student feedback.

    The IRIS Education and Outreach Program has been an integral part of IRIS for the past 10 years and during that time has worked to advance awareness and understanding of seismology and earth science while inspiring careers in geophysics. The focus on seismology and the use of seismic data has allowed the IRIS E&O program to develop and disseminate a unique suite of products and services for a wide range of audiences. One result of that effort has been increased access to the IRIS Data Management System by non-specialist audiences and simplified use of location and waveform data. The Seismic Monitor was one of the first Web-based tools for observing near-real-time seismicity. It continues to be the most popular IRIS web page, and thus it presents aspects of seismology to a very wide audience. For individuals interested in more detailed ground motion information, waveforms can be easily viewed using the Rapid Earthquake Viewer, developed by the University of South Carolina in collaboration with IRIS E&O. The Seismographs in Schools program gives schools the opportunity to apply for a low-cost educational seismograph and to receive training for its use in the classroom. To provide better service to the community, a new Seismographs in Schools website was developed in the past year with enhanced functions to help teachers improve their teaching of seismology. The site encourages schools to make use of seismic data and communicate with other educational seismology users throughout the world. Users can view near-real-time displays of other participating schools, upload and download data, and use the “find a teacher” tool to contact nearby schools that also may be operating seismographs. In order to promote and maintain program participation and communication, the site features a discussion forum to encourage and support the growing global community of educational seismograph users. Any data that is submitted to the Seismographs in Schools Website is also accessible

    Full Text Available Objectives: Contemporary dental radiology offers a wide spectrum of imaging methods but it also contributes to an increase in the participation of dental radiological diagnosis in the patient’s exposure to ionizing radiation. The aim of this study is to determine the absorbed doses of the brain, spinal column, thyroid and eye lens for patients during panoramic radiography, cephalometric radiography and cone beam computed tomography (CBCT. Material and Methods: The thermoluminescent dosimetry and anthropomorphic phantom was used for measuring the doses. The 15 panoramic, 4 cephalometric and 4 CBCT exposures were performed by placing high-sensitivity thermoluminescent detectors (TLD in 18 anatomical points of the phantom. Results: The maximum absorbed dose recorded during performed measurements corresponds to the point representing the brainstem and it is 10 mGy. The dose value recorded by the TLD placed in the thyroid during CBCT imaging in relation to the panoramic radiography differs by a factor of 13.5. Conclusions: Cone beam computed tomography, in comparison with panoramic or cephalometric imaging technique, provides higher radiation doses to the patients.

    Neutron radiography refers to the application of transmitted neutrons to analysis. In general, thermal neutron is used for neutron radiography. Thermal neutron is easily absorbed by light atoms, including hydrogen, boron and lithium, while it is not easily absorbed by such heavy atoms as tungsten, lead and uranium, permitting detection of impurities in heavy metals. Other neutrons than thermal neutron can also be applied. Cold neutron is produced from fast neutron using a moderator to reduce its energy down to below that of thermal neutron. Cold neutron is usefull for analysis of thick material. Epithermal neutron can induce resonance characteristic of each substance. With a relatively small reaction area, fast neutron permits observation of thick samples. Being electrically neutral, neutrons are difficult to detect by direct means. Thus a substance that releases charged particles is put in the path of neutrons for indirect measurement. X-ray film combined with converter screen for conversion of neutrons to charge particles is placed behind the sample. Photographing is carried out by a procedure similar to X-ray photography. Major institues and laboratories in Japan provided with neutron radiography facilities are listed. (Nogami, K.)

    The Fuji Computed Radiography (FCR) developed recently involves the following procedures; photography in the same way as the hitherto radiography, printing auto imaging plate of photostimulable phospher, conversion to electric signals, and recording reproduced images by computerization. Highly valuable images for diagnoses in the medical field have already been obtained by the FCR. Then, we attempted to study FCR images panoramically radiographed for jaw lesions in the field of oral surgery. Method for study: As the samples to be studied, the selected subjects were cases of periodontal diseases, fracture of the jaw, odontogenic cyst and tumor, etc. In the present study the FCR images of panoramic radiography were compared with hitherto panoramic flat radiograms. Result of study: Although the images of the FCR vary depending on the methods of treatment, that is, on how gradient processing and spatial frequency enhancement are, the method of purpose-fitting treatment provided diagnostically significant images for grasping bone lesions. The images obtained from this FCR permitted us to grasp more distinctly condition of alveolar bone resorption in periodontal diseases, running of minute fracture lines in fracture of the jaw, and characteristic images of bone resorption in odontogenic cysts and tumor, etc. Thus the images of the FCR are highly useful in diagnosing bone lesions, but granularity of the images themselves have still been questioned, and additionally the images vary depending on the methods of gradient processing and spatial frequency enhancement. Therefore further repeat studies are probably needed for these questions. (author)

    - Facebook (Menlo Park, California) is one of many online sites that provide potential educational tools for pathologists. We have each founded Facebook groups dedicated to anatomic pathology, in which members can share cases, ask questions, and contribute to discussions. - To report our experiences in founding and maintaining these Facebook groups and to characterize the contributed content. - We circulated a survey among the group founders, then compiled and analyzed the responses. - The groups varied in membership and in the quality of member contribution. Most posts were of pathology cases, although other topics (such as research articles) were also shared. All groups remained active and received posts from users all over the world, although all groups had many noncontributing members and received unwanted messages (which were screened and removed). Most founders were glad they had founded the groups because they provided an opportunity to both teach and learn. - Each analyzed Facebook group had a different character, and some downsides exist, but the groups all provided a no-cost way for pathologists and others across the world to interact online with many colleagues.

    This research explores the feasibility of using gamma-ray radiography in medical imaging. We will show that gamma-ray medical radiography has the potential to provide alternative diagnostic medical information to X-ray radiography. Approximately one Ci Am-241 radioactive source which emits mono-energetic 59.5 keV gamma rays was used. Several factors that influence the feasibility of this study were tested. They were the radiation source uniformity, image uniformity, and image quality parameters such as contrast, noise, and spatial resolution. In addition, several gamma-ray and X-ray images were acquired using humanoid phantoms. These images were recorded on computed radiography image receptors and displayed on a standard monitor. Visual assessments of these images were then conducted. The Am-241 radioactive source provided relatively uniform radiation exposure and images. Image noise and image contrast were mainly dependent on the exposure time and source size, whereas spatial resolution was dependent on source size and magnification factor. The gamma-ray humanoid phantom images were of lower quality than the X-ray images mainly due to the low radioactivity used and not enough exposure time. Nevertheless, the gamma-ray images displayed most of the main structures contained in the humanoid phantoms. Higher exposure rates and thus lower exposure times were estimated for different pure Am-241 source sizes that are hypothesized to provide high quality images similar to X-ray images. For instance, a 10 mm source size of pure Am-241 with 7 s exposure time should produce images similar in contrast and noise to X-ray images. This research paves the way for the production and usage of a highly radioactive Am-241 source with the potential to lead to the feasibility of acceptable quality medical gamma-ray radiography. - Highlights: ► Characterized the performance of gamma-ray radiography. ► Displayed medical images of humanoid phantoms using gamma radiography. ► Am-241

    A new technology has been implemented using an open-quotes active-detectorclose quotes comprised of two computed radiography (CR) imaging plates in a sandwich geometry for dual-energy radiography. This detector allows excellent energy separation, short exposure time, and high signal to noise ratio (SNR) for clinically robust open-quotes bone-onlyclose quotes and open-quotes soft-tissue onlyclose quotes images with minimum patient motion. Energy separation is achieved by two separate exposures at widely different kVp's: the high energy (120 kVp + 1.5 mm Cu filter) exposure is initiated first, followed by a short burst of intense light to erase the latent image on the front plate, and then a 50 kVp (low energy) exposure. A personal computer interfaced to the x-ray generator, filter wheel, and active detector system orchestrates the acquisition sequence within a time period of 150 msec. The front and back plates are processed using a CR readout algorithm with fixed speed and wide dynamic range. open-quotes Bone-onlyclose quotes and open-quotes soft-tissue onlyclose quotes images are calculated by geometric alignment of the two images and application of dual energy decomposition algorithms on a pixel by pixel basis. Resultant images of a calibration phantom demonstrate an increase of SNR 2 / dose by ∼73 times when compared to a single exposure open-quotes passive-detectorclose quotes comprised of CR imaging plates, and an ∼8 fold increase compared to a screen-film dual-energy cassette comprised of different phosphor compounds. In conclusion, dual energy imaging with open-quotes active detectorclose quotes technology is clinically feasible and can provide substantial improvements over conventional methods for dual-energy radiography

    Physicians and other healthcare professionals are often the end users of medical innovation; however, they are rarely involved in the beginning design stages. This often results in ineffective healthcare solutions with poor adoption rates. At the early design stage, innovation would benefit from input from healthcare professionals. This report describes the first-ever rehabilitation hackathon-an interdisciplinary and competitive team event aimed at accelerating and improving healthcare solutions and providing an educational experience for participants. Hackathons are gaining traction as a way to accelerate innovation by bringing together a diverse group of interdisciplinary professionals from different industries who work collaboratively in teams and learn from each other, focus on a specific problem ("pain point"), develop a solution using design thinking techniques, pitch the solution to participants, gather fast feedback and quickly alter the prototype design ("pivoting"). 102 hackers including 19 (18.6 %) physicians and other professionals participated, and over the course of 2 days worked in teams, pitched ideas and developed design prototypes. Three awards were given for prototypes that may improve function in persons with disabilities. 43 hackers were women (42.2 %) and 59 men (57.8 %); they ranged in age from 16 to 79 years old; and, of the 75 hackers who reported their age, 63 (84 %) were less than 40 years old and 12 (16 %) were 40 years or older. This report contributes to the emerging literature on healthcare hackathons as a means of providing interdisciplinary education and training and supporting innovation.

  3. Power Relations and Health Care Communication in Older Adulthood: Educating Recipients and Providers.

    Science.gov (United States)

    Eliassen, A Henry

    2016-12-01

    Unequal power relations lie just below the surface in much of today's discourse on health care communication with older adults. Focusing on pathologies or deficits tends to reinforce stereotypes of frailty and dependency, thus framing elders as a vulnerable group requiring special assistance. Implicit stereotyping frequently colors interactions of health care personnel with older clients and their families-interactions likely to affect elders' perceptions and health outcomes. Health care providers need to be attuned to the vast and growing diversity in today's older population, wherein many older adults are exemplars of what it takes to marshal resources and cope with multifaceted challenges. Thus, elders have the potential to teach medical personnel through narratives of resilience as well as tribulation. This potential can be fully realized, however, only in contexts where communication patterns characterized by paternalism, consumerism, and collaboration are mutually recognized and selectively challenged or implemented. Promising interventions to facilitate health care communication in older adulthood might well be directed toward (a) educating both recipients and providers to become more mindful of cues that evoke stereotypical thinking, (b) promoting an institutional culture that normalizes situationally appropriate assertive responses to stereotyping, and (c) formally ratifying older adults' life experience in the training of health care personnel. © The Author 2015.

  4. Narrative in interprofessional education and practice: implications for professional identity, provider-patient communication and teamwork.

    Science.gov (United States)

    Clark, Phillip G

    2014-01-01

    Health and social care professionals increasingly use narrative approaches to focus on the patient and to communicate with each other. Both effective interprofessional education (IPE) and practice (IPP) require recognizing the various values and voices of different professions, how they relate to the patient's life story, and how they interact with each other at the level of the healthcare team. This article analyzes and integrates the literature on narrative to explore: self-narrative as an expression of one's professional identity; the co-creation of the patient's narrative by the professional and the patient; and the interprofessional multi-vocal narrative discourse as co-constructed by members of the healthcare team. Using a narrative approach to thinking about professional identity, provider-patient communication, and interprofessional teamwork expands our thinking about both IPE and IPP by providing new insights into the nature of professional practice based on relationships to oneself, the patient, and others on the team. How professionals define themselves, gather and present information from the patient, and communicate as members of a clinical team all have important dimensions that can be revealed by a narrative approach. Implications and conclusions for the further development of the narrative approach in IPE and IPP are offered.

    To improve pain management practices, we developed an online interactive continuing education (CE) program for primary care providers (PCPs). This program follows the flow of clinical decision-making through simulated cases at critical pain treatment points along the pain treatment continuum. A randomized controlled trial was conducted to test the efficacy of this program. Participants were randomized to either the experimental condition or the control condition (online, text-based CE program). A total of 238 primary care providers were recruited through hospitals, professional newsletters, and pain conferences. Participants in both conditions reported significantly improved scores on knowledge (KNOW-PAIN 50), attitudes (CAOS), and pain practice behaviors (PPBS) scales over the four-month study. The experimental condition showed significantly greater change over time on the tamper-resistant formulations (TRFs) of opioids and dosing CAOS subscale compared with the control condition. Post hoc comparisons suggested that participants in the experimental condition were less likely to endorse use of opioid TRFs over time compared with the control condition. Exploratory analyses for potential moderators indicated a significant three-way interaction with time, condition, and discipline (i.e., physician vs other) for the impediments and concerns attitudes subscale and the early refill behaviors subscale. Post hoc comparisons indicated that physicians in the experimental condition exhibited the greatest change in attitudes and the nonphysicians exhibited the greatest change in reported behaviors in response to requests for early refills. Findings suggest online CE programs may positively impact PCPs' knowledge, attitudes, and pain practice behaviors but provide minimal evidence for the value of including interactivity. © 2016 American Academy of Pain Medicine.

    Learning chemistry is cumulative: basic knowledge and chemical calculation skills are required to gain understanding of higher content. However, we often suffer from students' lack of learning skills to acquire these concepts. One of the reasons is the lack of adequate training in the knowledge and skills of chemistry, and one of the reasons for this lack is the lack of adequate evaluation of training procedures and content. Team-based learning (TBL) is a strong method for providing training in the knowledge and skills of chemistry and reaffirms the knowledge and skills of students of various levels. In our faculty, TBL exercises are provided for first-year students concurrently with lectures in physical chemistry and analytical chemistry. In this study, we researched the adoption of a peer evaluation process for this participatory learning model. Questionnaires taken after TBL exercises in the previous year showed a positive response to TBL. Further, a questionnaire taken after TBL exercises in the spring semester of the current year also yielded a positive response not only to TBL but also to peer evaluation. In addition, a significant correlation was observed between the improvement of students' grades in chemistry classes and the feeling the percentage (20%) of peer evaluation in overall evaluation low (logistic regression analysis, p=0.022). On the basis of the findings, we argue that TBL provides a generic, practical learning environment including an effective focus on learning strategy and evaluation of knowledge, skills, and attitudes, and studies on the educational effects of TBL and peer evaluation.

    Background: Practice education is a core component of undergraduate health programs, with the characteristics of the practice educator reported to have an influence on student experience during practical. This study analyses Australian student perceptions from six allied health professional undergraduate programs, to identify the characteristics of the ideal practice educator leading to successful placement experiences. Methods: An existing survey developed for medical students was modified to incorporate both quantitative and qualitative responses. Participants included all students enrolled in six undergraduate health professions in the School of Health Sciences at the University of Newcastle, Australia (n = 1485). Students were invited to complete the survey via hard copy or online. Results: There was a 54% response rate. The most valued characteristics were non-judgemental, clarity and feedback. The three least valued characteristics were scholarly activity, role model and practices evidence base practice. Students identified the importance of their relationship (respectful, inspirational and supportive) with the practice educator as being fundamental to a productive placement. Conclusion: The characteristics identified by respondents were common to all six professions, with little differences between gender, year of program or number of placements completed. This study suggests that the attitude of the practice educator towards the student is one of the key factors that underpin the success of practice experience across allied health professions. - Highlights: • The most important characteristics were non-judgmental and clarity. • The least important characteristics were scholarly activity and being a role model. • Female students valued all characteristics except being a role model as being more important. • Participants older than 30 years valued being “available”, “aware” and “well prepared” more than the younger participants. • High

    Real-time neutron radiography is being evaluated for studying the dynamic behavior of two phase flow and for measuring void fraction in vertical and inclined water ducts. This technique provides a unique means of visualizing the behavior of fluid flow inside thick metal enclosures. To simulate vapor conditions encountered in a fluid flow duct, an air-water flow system was constructed. Air was injected into the bottom of the duct at flow rates up to 0.47 I/s (1 cfm). The water flow rate was varied between 0--3.78 I/m (0--1 gpm). The experiments were performed at the Pennsylvania State University nuclear reactor facility using a real-time neutron radiography camera. With a thermal neutron flux on the order of 10 6 n/cm 2 /s directed through the thin duct dimension, the dynamic behavior of the air bubbles was clearly visible through 5 cm (2 in.) thick aluminum support plates placed on both sides of the duct wall. Image analysis techniques were employed to extract void fractions from the data which was recorded on videotape. This consisted of time averaging 256 video frames and measuring the gray level distribution throughout the region. The distribution of the measured void fraction across the duct was determined for various air/water mixtures. Details of the results of experiments for a variety of air and water flow conditions are presented

  14. Dose optimisation in computed radiography

    Schreiner-Karoussou, A.

    2005-01-01

    After the installation of computed radiography (CR) systems in three hospitals in Luxembourg a patient dose survey was carried out for three radiographic examinations, thorax, pelvis and lumbar spine. It was found that the patient doses had changed in comparison with the patient doses measured for conventional radiography in the same three hospitals. A close collaboration between the manufacturers of the X-ray installations, the CR imaging systems and the medical physicists led to the discovery that the speed class with which each radiographic examination was to be performed, had been ignored, during installation of the digital imaging systems. A number of procedures were carried out in order to calibrate and program the X-ray installations in conjunction with the CR systems. Following this optimisation procedure, a new patient dose survey was carried out for the three radiographic examinations. It was found that patient doses for the three hospitals were reduced.

    The inversion algorithm based on the maximum entropy method (MEM) removes unwanted effects in high energy imaging resulting from an uncollimated source interacting with a finitely thick scintillator. The algorithm takes as input the image from the thick scintillator (TS) and the radiography setup geometry. The algorithm then outputs a restored image which appears as if taken with an infinitesimally thin scintillator (ITS). Inversion is accomplished by numerically generating a probabilistic model relating the ITS image to the TS image and then inverting this model on the TS image through MEM. This reconstruction technique can reduce the exposure time or the required source intensity without undesirable object blurring on the image by allowing the use of both thicker scintillators with higher efficiencies and closer source-to-detector distances to maximize incident radiation flux. The technique is applicable in radiographic applications including fast neutron, high-energy gamma and x-ray radiography using thick scintillators.

    2015-12-01

    Various organizations such as the Group on Earth Observations (GEO) have developed a structure for general thematic areas in Earth science research, however the Climate Data Initiative (CDI) is addressing the challenging goal of organizing such datasets around core themes specifically related to climate change impacts. These thematic areas, which currently include coastal flooding, food resilience, ecosystem vulnerability, water, transportation, energy infrastructure, and human health, form the core of a new college course at the University of Alabama in Huntsville developed around real-world applications in the Earth sciences. The goal of this course is to educate students on the data available and scope of GIS applications in Earth science across the CDI climate themes. Real world applications and datasets serve as a pedagogical tool that provide a useful medium for instruction in scientific geospatial analysis and GIS software. With a wide range of potential research areas that fall under the rubric of "Earth science", thematic foci can help to structure a student's understanding of the potential uses of GIS across sub-disciplines, while communicating core data processing concepts. The learning modules and use-case scenarios for this course demonstrate the potential applications of CDI data to undergraduate and graduate Earth science students.

    Enrollment in MD PhD programs offers the opportunity of a basic science education for medical students and doctors. These programs originated in the USA where structured programs have been offered for many years, but now German universities also run MD PhD programs. The MD PhD programs provided by German universities were investigated regarding entrance requirements, structure and financing modalities. An internet and telephone-based search was carried out. Out of 34 German universities 22 offered MD PhD programs. At 15 of the 22 universities a successfully completed course of studies in medicine was required for enrollment, 7 programs admitted medical students in training and 7 programs required a medical doctoral thesis, which had to be completed with at least a grade of magna cum laude in 3 cases. Financing required scholarships in many cases. Several German universities currently offer MD PhD programs; however, these differ considerably regarding entrance requirements, structure and financing. A detailed analysis investigating the success rates of these programs (e.g. successful completion and career paths of graduates) would be of benefit.

    YouTube has emerged as a potential teaching tool. Studies of the teaching potential of YouTube videos have not addressed health care provider (HCP) satisfaction; a necessary prerequisite for any teaching tool. We conducted a 4-month investigation to determine HCP satisfaction with a nephrology-specific YouTube channel. The Nephrology On-Demand YouTube channel was analyzed from January 1 through April 30, 2011. Sixty-minute nephrology lectures at East Carolina University were compressed into 10-minute videos and uploaded to the channel. HCPs were asked to answer a 5-point Likert questionnaire regarding the accuracy, currency, objectivity and usefulness of the digital format of the teaching videos. Means, standard deviations and 2-sided chi-square testing were performed to analyze responses. Over 80% of HCPs considered the YouTube channel to be accurate, current and objective. A similar percentage considered the digital format useful despite the compression of videos and lack of audio. The nephrology-specific YouTube channel has the potential to educate HCPs of various training backgrounds. Additional studies are required to determine if such specialty-specific channels can improve knowledge acquisition and retention.

    Objective. To summarize the effects of media methods used in continuing education (CE) programs on providing clinical community pharmacy services and the methods used to evaluate the effectiveness of these programs. Methods. A systematic review was performed using Medline, SciELO, and Scopus databases. The timeline of the search was 1990 to 2013. Searches were conducted in English, Portuguese, and Spanish. Results. Nineteen articles of 3990 were included. Fourteen studies used only one media method, and the live method (n=11) was the most frequent (alone or in combination). Only two studies found that the CE program was ineffective or partially effective; these studies used only the live method. Most studies used nonrobust, nonvalidated, and nonstandardized methods to measure effectiveness. The majority of studies focused on the effect of the CE program on modifying the knowledge and skills of the pharmacists. One study assessed the CE program’s benefits to patients or clients. Conclusion. No evidence was obtained regarding which media methods are the most effective. Robust and validated methods, as well as assessment standardization, are required to clearly determine whether a particular media method is effective. PMID:27402991

    1990-01-01

    Increased receptor speed in panoramic radiography is useful in reducing patient exposure if it doesn't substantially decrease the diagnostic quality of the resultant image. In a laboratory investigation four rare earth screen/film combinations were evaluated ranging in relative speed from 400 to 1200. The results indicated that an exposure reduction of approximately 15 percent can be achieved by substituting a 1200 speed system for a 400 speed system without significantly affecting the diagnostic quality of the image

    The Matter-Radiation Interactions in Extremes (MaRIE) experimental facility will be used to discover and design the advanced materials needed to meet 21st century national security and energy security challenges. This new facility will provide the new tools scientists need to develop next-generation materials that will perform predictably and on-demand for currently unattainable lifetimes in extreme environments. The MaRIE facility is based on upgrades to the existing LANSCE 800-MeV proton linac and a new 12-GeV electron linac and associated X-ray FEL to provide simultaneous multiple probe beams, and new experimental areas. In addition to the high-energy photon probe beam, both electron and proton radiography capabilities will be available at the MaRIE facility. Recently, detailed radiography system studies have been performed to develop conceptual layouts of high-magnification electron and proton radiography systems that can meet the experimental requirements for the expected first experiments to be performed at the facility. A description of the radiography systems, their performance requirements, and a proposed facility layout are presented.

  11. Radiography using californium-252 neutron sources

    International Nuclear Information System (INIS)

    Ray, J.W.

    1975-01-01

    The current status in the technology of neutron radiography using californium-252 neutron sources is summarized. Major emphasis is on thermal neutron radiography since it has the widest potential applicability at the present time. Attention is given to four major factors which affect the quality and useability of thermal neutron radiography: source neutron thermalization, neutron beam extraction geometry, neutron collimator dimensions, and neutron imaging methods. Each of these factors has a major effect on the quality of the radiographs which are obtained from a californium source neutron radiography system and the exposure times required to obtain the radiographs; radiograph quality and exposure time in turn affect the practicality of neutron radiography for specific nondestructive inspection applications. A brief discussion of fast neutron radiography using californium-252 neutron sources is also included. (U.S.)

  12. New prospect in neutron radiography

    International Nuclear Information System (INIS)

    Cluzeau, S.

    1991-01-01

    Neutron radiography is a very useful non-destructive testing (NDT) method which frequently complements classical X-ray inspection. Numerous inspections in some fields are currently performed at reactor-based neutron radiography facilities but many other interesting applications in different fields are at present not considered because the objects to be tested cannot be moved to a reactor. It is the goal of the DIANE project, to allow the utilization of this NDT method in industrial facilities by developing a safe and convenient neutron radiography equipment using an ''on-off'' neutron source. As a result of the efforts of the four European partners, a first laboratory demonstration model is currently in operation in Germany and a fully mobile second one is expected by the end of 1992. Good radiographs are obtained with exposure times in the range of a few seconds to ten minutes using an electronic imaging system. The fast neutron generator uses a sealed neutron tube delivering 5.10 11 neutrons.cm -2 .s -1 in 4 π steradian; with a collimator ratio of about 12, the fluence rate onto the object is then close to 1,5.10 5 thermal neutrons.cm -2 .s -1 .

  13. Medical radiography with fast neutrons

    International Nuclear Information System (INIS)

    Duehmke, E.

    1980-01-01

    Neutron radiography is important in medicine for two reasons. On the one hand, macroradiographical findings are different from X-ray findings, i.e. new information may be gained on the morphology of humans and animals. On the other hand, there is a direct practical application in the radiotherapy of malignant tumours if one considers the assessment of the growth of malignant processes. Fast neutrons are required for neutron radiographies of biological objects with a diameter of more than 2 cm. In addition sensitive, two-dimensional detectors must be used which are selective for fast neutrons. The book describes the optimisation and sensitisation of a detector using the example of cellulose nitrate foil for fast reactor neutrons. Images of human spinal chords with tumours proved by pathological and anatomical examinations give a better picture of the dimensions of the tumour than comparative X-ray pictures. For examinations of living patients, neutron radiography should be applied only in those tumour-bearing parts of the bodies in which radiation treatment is required for therapeutical purposes anyway.

    Reid, D.W.

    1984-01-01

    There are numerous instances where the availability of a portable high-energy radiography machine that could be transported to the inspection site with relative ease would save time, money, and make radiography of permanent installations, such as bridges, possible. One such machine, the Minac built by Schoenberg Radiation Inc., is commercially available. It operates at 9.3 GHz, has an electron energy on target of 3.5 MeV, and an output dose rate of 100 R/min. A second portable accelerator, recently completed at the Los Alamos National Laboratory, operates at 2.998 GHz, has electron energies on target of 6, 8, and 10 MeV, and an output dose rate of 800 R/min at 8 MeV. This paper discusses the need for and applications of portable accelerators for radiography. Physical characteristics and beam parameters of both machines are examined in detail. Problems of operating at higher frequencies to further minimize size and weight are discussed

  15. Barriers to nutrition education for older adults, and nutrition and aging training opportunities for educators, healthcare providers,volunteers and caregivers.

    Meck Higgins, Mary; Barkley, Mary Clarke

    2004-01-01

    Literature citations of barriers to nutrition education found in those who teach and care for older adults, as well as within older adults themselves, are discussed. No attempt was made to compare educational barriers for learners of varying ages. These obstacles need to be addressed in order for nutrition to be taught or learned effectively so that nutrition practices and health improve. Barriers for healthcare professionals to providing nutrition education include misconceptions and stereotypes about older adults and about their nutritional concerns; lack of attention to and lack of funding for older adult educational programs; and difficulties recruiting older learners. Hindrances for older adults in responding to nutrition education can be categorized as attitudinal, motivational, environmental, and related to low literacy and poverty. Published examples of opportunities for education and training about nutrition and aging that are in place for health educators, healthcare providers, volunteers and caregivers regarding nutrition and aging are discussed. Suggestions are presented regarding future efforts to minimize educational barriers and to provide training for healthcare professionals, volunteers and caregivers. New research is needed in this field of study in order to realize the potential quality of life benefits and reduced healthcare costs associated with providing effective nutrition education to older adults. This is one of a series of reviews of recent literature on nutrition education for older adults.

    Rossen, B.; Laursen, N.O.; Just, S.

    The results of chest radiography in 581 patients with blunt minor thoracic trauma were reviewed. Frontal and lateral views of the chest indicated pathology in 72 patients (12.4%). Pneumothorax was present in 16 patients; 4 had hemothorax. The physical examination and the results of chest radiography were not in accordance because in 6(30%) of the 20 patients with hemo/-pneumothorax the physical examination was normal. Consequently there is wide indication for chest radiography after minor blunt chest trauma.

    Knapp, K.M.; Wright, C.; Clarke, H.; McAnulla, S.J.; Nightingale, J.M.

    2017-01-01

    Introduction: Academia is one area of practice in which radiographers can specialise; they compile approximately 2% of the total radiography profession in the UK, but are highly influential and essential for the education and development of the workforce in addition to undertaking research. However, the academic environment is very different to clinical practice and a period of transition is required. Methods: Data were collated to explore the age and retirement profile of the academic radiography workforce in the UK; to understand the research time allocated to this workforce; the time required to develop a clinical radiographer into an academic and the mentorship and succession planning provisions nationally. An online UK wide survey was conducted and sent to all 24 Universities delivering radiography education within the UK. Results: Eighteen out of 24 Universities in the UK responded to the survey. Approximately 30% of radiography academics are due to retire over the next 10 years, with over 25% of radiographers who currently hold a doctorate qualification included within this figure. Those entering academia have notably lower qualifications as a group than those who are due to retire. Developing clinical radiographers into academics was thought to take 1–3 years on average, or longer if they are required to undertake research. Conclusion: There is vulnerability in the academic radiography workforce. Higher education institutions need to invest in developing the academic workforce to maintain research and educational expertise, which is underpinned by master's and doctorate level qualifications. - Highlights: • Approximately 30% of radiography academics are due to retire over the next 10 years. • Over 25% of radiographers who currently hold a doctorate qualification included due to retire within 10 years. • Those entering academia have significantly lower qualifications as a group than those who are due to retire. • There is vulnerability in the

    Harrell, Angela; Matthews, Eric

    2016-07-01

    To determine whether a relationship exists between the number of clinical sites available in radiography programs accredited by the Joint Review Committee on Education in Radiologic Technology and the job placement rates of graduates. We performed a secondary analysis of data on job placement rates and the number of clinical sites available in 438 degree-granting radiography programs from January 2015 to March 2015. A weak, negative, nonsignificant correlation existed between the number of clinical sites and the job placement rate (Spearman's rho = -.113, n = 438, P = .018). The coefficient of determination was 1.28%.Discussion Research evaluating factors contributing to graduate employability is limited but indicates no need for radiography program administrators to adjust clinical site numbers solely on the basis of improving graduate employability. The number of clinical sites available in a radiography program is not related to the job placement rate of its graduates. ©2016 American Society of Radiologic Technologists.

    NASA is working with four newly-formed Science Education and Public Outreach Forums (SEPOFs) to increase the overall coherence of the Science Mission Directorate (SMD) Education and Public Outreach (E/PO) program. SEPOFs support the astrophysics, heliophysics, planetary and Earth science divisions of NASA SMD in three core areas: * E/PO Community Engagement and Development * E/PO Product and Project Activity Analysis * Science Education and Public Outreach Forum Coordination Committee Service. SEPOFs are collaborating with NASA and external science and education and outreach communities in E/PO on multiple levels ranging from the mission and non-mission E/PO project activity managers, project activity partners, and scientists and researchers, to front line agents such as naturalists/interpreters, teachers, and higher education faculty, to high level agents such as leadership at state education offices, local schools, higher education institutions, and professional societies. The overall goal for the SEPOFs is increased awareness, knowledge, and understanding of scientists, researchers, engineers, technologists, educators, product developers, and dissemination agents of best practices, existing NASA resources, and community expertise applicable to E/PO. By coordinating and supporting the NASA E/PO Community, the NASA/SEPOF partnerships will lead to more effective, sustainable, and efficient utilization of NASA science discoveries and learning experiences.

  10. Neutron radiography by using JSW baby cyclotron

    International Nuclear Information System (INIS)

    Toda, Yojiro

    1995-01-01

    At present, JSW baby cyclotrons are mostly used for the production of the radioisotopes for medical use. The attempt to use this baby cyclotron for neutron radiography began already in 1981. The feasibility of the neutron radiography for the explosives in metallic cases which are used for H1 rockets was investigated. In 1983, it was shown that the neutron radiography by using the baby cyclotron in Muroran Works, Japan Steel Works, Ltd. was able to be carried out as a routine work. Since then, the nondestructive inspection by neutron radiography has been performed for rocket pyrotechnic articles, and contributed to heighten their reliability. Further, the radiography by using fast neutrons was developed and put to practical use for recent large H2 rockets. The JSW baby cyclotron BC 168 which has been used for neutron radiography can accelerate 16 MeV protons or 8 MeV deuterons up to 50 μA. The principle of thermal neutron radiography is the generation of fast neutrons by irradiating a Be target with the proton beam accelerated by a baby cyclotron, the moderation of the fast neutrons, the formation of the thermal neutron flux of uniform distribution with a collimator, the thermal neutron flux hitting the Gd plate in a film cassette through an object, and the exposure of an X-ray film to electrons from the Gd plate. Fast neutron radiography apparatus, and commercial neutron radiography are described. (K.I.)

    Link, T.M.; Kessler, T.; Lange, T.; Overbeck, J.; Fiebich, M.; Peters, P.E.

    1994-01-01

    The aim of the study was to evaluate the potential of magnification radiography in diagnosing fracture healing and assessing its complications. Seventy-three patients with fractures or who had undergone osteotomy were radiographed with both conventional (non-magnified) and magnification (5-fold) techniques. Since 10 patients were radiographed twice and 1 three times, 83 radiographs using each technique were obtained. All radiographs were analysed and the findings correlated with the patients' follow-up studies. The microfocal X-ray unit used for magnification radiography had a focal spot size of 20-130 μm. As an imaging system, digital luminescence radiography was employed with magnification, while normal film-screen systems were used with conventional radiography. Magnification radiography proved superior to conventional radiography in 47% of cases: endosteal and periosteal callus formations were seen earlier and better in 26 cases, and osseous union could be evaluated with greater certainty in 33 cases. In 49% of cases magnification radiography was equal and in 4% inferior to conventional radiography. Additionally an ''inter-observer analysis'' was carried out. Anatomical and pathological structures were classified into one of four grades. Results were significantly (P < 0.01) better using magnification radiography. We conclude that the magnification technique is a good method for monitoring fracture healing in its early stages. (orig.)

  12. Digital and analogue industrial radiography, application fields

    International Nuclear Information System (INIS)

    Willems, Peter; Millord, Erik Yardin

    2000-01-01

    Full text: Reusable phosphor screens for computer radiography (CR), amorphous selenium screens for direct radiography (DR), film digitalisation (FD) constitute imaging methods accepted by industry and are used for non-destructive radiographic testing (RT). Economic pressures are involving and affecting digital RT technology. Standards and codes for film radiography and radioscopy qualification do no longer cover the wide range of digital RT applications. It will be our task to optimise the performance of digital RT characterisation and to create appropriate examination methods to use all these new and existent technologies. In the meantime, an increasing automation and control of manual methods of analogue radiography can as well be expected. (author)

    Mothiram, Ursula; Brennan, Patrick C; Lewis, Sarah J; Moran, Bernadette; Robinson, John

    2014-01-01

    Digital radiography (DR) technologies have the advantage of a wide dynamic range compared to their film-screen predecessors, however, this poses a potential for increased patient exposure if left unchecked. Manufacturers have developed the exposure index (EI) to counter this, which provides radiographers with feedback on the exposure reaching the detector. As these EIs were manufacturer-specific, a wide variety of EIs existed. To offset this, the international standardised EI has been developed by the International Electrotechnical Commission (IEC) and the American Association of Physicists in Medicine (AAPM). The purpose of this article is to explore the current literature relating to EIs, beginning with the historical development of the EI, the development of the standardised EI and an exploration of common themes and studies as evidenced in the research literature. It is anticipated that this review will provide radiographers with a useful guide to understanding EIs, their application in clinical practice, limitations and suggestions for further research

Forty hospitalized patients were educated using the warfarin video and included for analysis. The majority of patients were new to warfarin therapy (65%). Forty-three percent of patients passed the pre-video knowledge test, and 90% passed the post-video knowledge test (P iPad and found it easy to use. Patients who were younger (iPad more than older patients (P = 0.01) and male subjects (P = 0.02), respectively. Also, younger patients found the iPad easier to use compared with patients who were older (P = 0.01). Educating hospitalized patients about warfarin by using a video on an iPad was effective. Video education on an iPad may be an alternative to traditional education in the hospital setting.

    The ability of computed tomography and radiography to detect changes associated with nasal neoplasia was compared in dogs. Eighteen areas or anatomic structures were evaluated in 21 dogs for changes indicative of neoplasia. Computed tomography was superior (P < or = 0.05) to radiography for detecting changes in 14 of 18 areas. Radiography was not superior for detecting changes in any structure or area. Computed tomography reveals vital information not always detected radiographically to assist in providing a prognosis and in planning treatment for nasal neoplasms in dogs

    Abdominal radiography and ultrasonography are commonly used as part of the initial diagnostic plan for cats with nonspecific signs of abdominal disease. This retrospective study compared the clinical usefulness of abdominal radiography and ultrasonography in 105 feline patients with signs of abdominal disease. The final diagnosis was determined more commonly with ultrasonography (59%) compared to radiography (25.7%). Ultrasonography was also able to provide additional clinically relevant information in 76% of cases, and changed or refined the diagnosis in 47% of cases. Based on these findings, ultrasonography may be sufficient as an initial diagnostic test for the investigation of feline abdominal disease. PMID:26483582

    To assess the effect of provision of free glasses on academic performance in rural Chinese children with myopia. Cluster randomized, investigator masked, controlled trial. 252 primary schools in two prefectures in western China, 2012-13. 3177 of 19,934 children in fourth and fifth grades (mean age 10.5 years) with visual acuity 6/12 with glasses. 3052 (96.0%) completed the study. Children were randomized by school (84 schools per arm) to one of three interventions at the beginning of the school year: prescription for glasses only (control group), vouchers for free glasses at a local facility, or free glasses provided in class. Spectacle wear at endline examination and end of year score on a specially designed mathematics test, adjusted for baseline score and expressed in standard deviations. Among 3177 eligible children, 1036 (32.6%) were randomized to control, 988 (31.1%) to vouchers, and 1153 (36.3%) to free glasses in class. All eligible children would benefit from glasses, but only 15% wore them at baseline. At closeout glasses wear was 41% (observed) and 68% (self reported) in the free glasses group, and 26% (observed) and 37% (self reported) in the controls. Effect on test score was 0.11 SD (95% confidence interval 0.01 to 0.21) when the free glasses group was compared with the control group. The adjusted effect of providing free glasses (0.10, 0.002 to 0.19) was greater than parental education (0.03, -0.04 to 0.09) or family wealth (0.01, -0.06 to 0.08). This difference between groups was significant, but was smaller than the prespecified 0.20 SD difference that the study was powered to detect. The provision of free glasses to Chinese children with myopia improves children's performance on mathematics testing to a statistically significant degree, despite imperfect compliance, although the observed difference between groups was smaller than the study was originally designed to detect. Myopia is common and rarely corrected in this setting.Trial Registration

    Analysis of accidents occurring in industrial radiography in Brazil from 2005 until 2010 led to the study of the main characteristics of the events, their risks and dangers. This study outlines the main doubts on the subject, through a simplified analysis of the contents of high dose reports sent to CNEN by the companies that provide services for industrial radiography and from examining the growing number of radioactive sources for industrial radiography in Brazil, over this period. We classified the recorded events, as incidents, accidents, negligence, sabotage, and others, and studied their main consequences. We concluded that from 76 accidents that occurred during that period - 25 were real accidents, 13 minor accidents and 22 were inadvertent incidents. We found that the rate of growth in the number of sources is much greater than the rate of growth of accidents, with a ratio of 7.57 between them. The continuation of this study over some years, will allow the construction of a pyramid of accidents like the one developed by the Insurance Company of North America, specifically for industrial radiography to forecast the number of incidents and accidents that lead to serious or fatal injury.

    2008-07-01

    In the present paper a new radiography technique, the 'Neutron Induced Electron Radiography' - NIER, to inspect low thickness samples on the order of micra, has been developed. This technique makes use of low energy electrons as penetrating radiation generated from metallic gadolinium screens when irradiated by thermal neutrons. The conditions to obtain the best image for the conventional X-ray film Kodak-AA were determined by using a digital system to quantify the darkening level of the film. The irradiations have been performed at a radiography equipment installed at the beam-hole no. 8 of the 5 MW IEA-R1 nuclear research reactor of IPEN-CNEN/SP. The irradiation time to obtain the best radiography was 100 seconds and for such condition the technique was able to discern 1 {mu}m in 24 {mu}m of aluminum at a resolution of 32 {mu}m. By visual comparison the images obtained by the NIER shown a higher quality when compared with the ones from other usual techniques the make use of electrons a penetrating radiation and films for image registration. Furthermore the use of the digital system has provided a smaller time for data acquisition and data analysis as well as an improvement in the image visualization. (author)

    2003-01-01

    Introduction: While radiography is currently developing a research base, which is important in terms of professional development and informing practice and policy issues in the field, the amount of research published by radiographers remains limited. However, a range of qualitative methods offer further opportunities for radiography research. Purpose: This paper briefly introduces a number of key qualitative methods (qualitative interviews, focus groups, observational methods, diary methods and document/text analysis) and sketches one possible framework for future qualitative work in radiography research. The framework focuses upon three areas for study: intra-professional issues; inter-professional issues; and clinical practice, patient and health delivery issues. While the paper outlines broad areas for future focus rather than providing a detailed protocol for how individual pieces of research should be conducted, a few research questions have been chosen and examples of possible qualitative methods required to answer such questions are outlined for each area. Conclusion: Given the challenges and opportunities currently facing the development of a research base within radiography, the outline of key qualitative methods and broad areas suitable for their application is offered as a useful tool for those within the profession looking to embark upon or enhance their research career

    2009-01-01

    During the last two decades screen-film (SF) systems have been replaced by digital X-ray systems. The advent of digital technologies brought a number of digital solutions based on different detector and readout technologies. Improvements in technology allowed the development of new digital technologies for projection radiography such as computed radiography (CR) and digital radiography (DR). The large number of scientific papers concerning digital X-ray systems that have been published over the last 25 years indicates the relevance of these technologies in healthcare. There are important differences among different detector technologies that may affect system performance and image quality for diagnostic purposes. Radiographers are expected to have an effective understanding of digital X-ray technologies and a high level of knowledge and awareness concerning the capabilities of these systems. Patient safety and reliable diagnostic information are intrinsically linked to these factors. In this review article - which is the first of two parts - a global overview of the digital radiography systems (both CR and DR) currently available for clinical practice is provided

    The number of rejected images is an indicator of image quality and unnecessary imaging at a radiology department. Image reject analysis was frequent in the film era, but comparably few and small studies have been published after converting to digital radiography. One reason may be a belief that rejects have been eliminated with digitalization. To measure the extension of deleted images in direct digital radiography (DR), in order to assess the rates of rejects and unnecessary imaging and to analyze reasons for deletions, in order to improve the radiological services. All exposed images at two direct digital laboratories at a hospital in Norway were reviewed in January 2014. Type of examination, number of exposed images, and number of deleted images were registered. Each deleted image was analyzed separately and the reason for deleting the image was recorded. Out of 5417 exposed images, 596 were deleted, giving a deletion rate of 11%. A total of 51.3% were deleted due to positioning errors and 31.0% due to error in centering. The examinations with the highest percentage of deleted images were the knee, hip, and ankle, 20.6%, 18.5%, and 13.8% respectively. The reject rate is at least as high as the deletion rate and is comparable with previous film-based imaging systems. The reasons for rejection are quite different in digital systems. This falsifies the hypothesis that digitalization would eliminates rejects. A deleted image does not contribute to diagnostics, and therefore is an unnecessary image. Hence, the high rates of deleted images have implications for management, training, education, as well as for quality

    PURPOSE We aimed to determine the radiation doses delivered to patients undergoing general examinations using computed or digital radiography systems in Turkey. MATERIALS AND METHODS Radiographs of 20 patients undergoing posteroanterior chest X-ray and of 20 patients undergoing anteroposterior kidney-ureter-bladder radiography were evaluated in five X-ray rooms at four local hospitals in the Ankara region. Currently, almost all radiology departments in Turkey have switched from conventional radiography systems to computed radiography or digital radiography systems. Patient dose was measured for both systems. The results were compared with published diagnostic reference levels (DRLs) from the European Union and International Atomic Energy Agency. RESULTS The average entrance surface doses (ESDs) for chest examinations exceeded established international DRLs at two of the X-ray rooms in a hospital with computed radiography. All of the other ESD measurements were approximately equal to or below the DRLs for both examinations in all of the remaining hospitals. Improper adjustment of the exposure parameters, uncalibrated automatic exposure control systems, and failure of the technologists to choose exposure parameters properly were problems we noticed during the study. CONCLUSION This study is an initial attempt at establishing local DRL values for digital radiography systems, and will provide a benchmark so that the authorities can establish reference dose levels for diagnostic radiology in Turkey.

    Medical staff must be able to perform accurate initial interpretations of radiography to prevent diagnostic errors. Education in medical image interpretation is an ongoing need that is addressed by text-based and e-learning platforms. The effectiveness of these methods has been previously reported. Here, we describe the effectiveness of an e-learning platform used for medical image interpretation education. Ten third-year medical students without previous experience in chest radiography interpretation were provided with e-learning instructions. Accuracy of diagnosis using chest radiography was provided before and after e-learning education. We measured detection accuracy for two image groups: nodular shadow and ground-glass shadow. We also distributed the e-learning system to the two groups and analyzed the effectiveness of education for both types of image shadow. The mean correct answer rate after the 2-week e-learning period increased from 34.5 to 72.7%. Diagnosis of the ground glass shadow improved significantly more than that of the mass shadow. Education using the e-leaning platform is effective for interpretation of chest radiography results. E-learning is particularly effective for the interpretation of chest radiography images containing ground glass shadow.

    Within a clinical education setting, the value of role models and prescribed mentors can be seen as an important influence in shaping the student's future as a diagnostic radiographer. A study was undertaken to create a new understanding of how diagnostic radiography students perceive role models and professional behavior in the workforce. The study aimed to determine the impact of clinical education in determining modeling expectations, role model identification and attributes, and the integration of academic education and "hands-on" clinical practice in preparing diagnostic radiography students to enter the workplace. Thirteen final-year (third-year) diagnostic radiography students completed an hour-long interview regarding their experiences and perceptions of role models while on clinical placement. The key concepts that emerged illustrated that students gravitate toward radiographers who enjoy sharing practical experiences with students and are good communicators. Unique to diagnostic radiography, students made distinctions about the presence of role models in private versus public service delivery. This study gives insight to clinical educators in diagnostic radiography and wider allied health into how students perceive role models, interact with preceptors, and combine real-life experiences with formal learning.

    Full Text Available Dental caries is the most prevalent chronic childhood disease in the United States. Dental caries affects the health of 60–90% of school-aged children worldwide. The prevalence of untreated early childhood dental caries is 19% for children 2–5 years of age in the U.S. Some factors that contribute to the progression of dental caries include socioeconomic status, access to dental care, and lack of anticipatory guidance. The prevalence of dental caries remains highest for children from specific ethnic or racial groups, especially those living in underserved areas where there may be limited access to a dentist. Although researchers have acknowledged the various links between oral health and overall systemic health, oral health care is not usually a component of pediatric primary health care. To address this public health crisis and oral health disparity in children, new collaborative efforts among health professionals is critical for dental disease prevention and optimal oral health. This evaluation study focused on a 10-week interprofessional practice and education (IPE course on children’s oral health involving dental, osteopathic medical, and nurse practitioner students at the University of California, San Francisco. This study’s objective was to evaluate changes in knowledge, confidence, attitude, and clinical practice in children’s oral health of the students completed the course. Thirty-one students participated in the IPE and completed demographic questionnaires and four questionnaires before and after the IPE course: (1 course content knowledge, (2 confidence, (3 attitudes, and (4 clinical practice. Results showed a statistically significant improvement in the overall knowledge of children’s oral health topics, confidence in their ability to provide oral health services, and clinical practice. There was no statistically significant difference in attitude, but there was an upward trend toward positivity. To conclude, this IPE

    The development of digital radiography (DR) has provided numerous benefits for pediatric imaging, including the ability to post-process images and to make images immediately available for access by care providers. However, DR presents several significant challenges for the radiologic technologists who are responsible for operating the equipment and producing high-quality images in children. This paper discusses those challenges, including lack of standardization among vendors, particularly with regard to the exposure indicator; lack of pediatric-specific educational materials and pediatric techniques; the need for manual technique instead of the use of automatic exposure control in smaller children; and complications related to field size, collimation and shielding in small children. Specific actions and design modifications that might facilitate the effective management of these challenges will be also described. The implementation of measures to promote the production of optimal images while minimizing radiation exposure requires cooperation and communication among imaging professionals, manufacturers and regulatory agencies.

    The purpose of the review was the synthesis of the literature data and the results of our radiobiological (biodosimetric) research on the development of radiation-associated tumors as a result of medical radiography (X-ray) diagnostic. Medical X-ray examinations contribute the most to the excess of radiation exposure of the population, much of which is subject to examination to diagnose the underlying disease, the dynamic observation of the patient during treatment, the research of related diseases, and preventative examinations. The review provides arguments for the necessity of developing a more balanced indication for preventative radiological examination of the population in the aftermath of radio-ecological crisis caused by the Chornobyl accident, taking into account the likelihood of radiation carcinogenesis. The problems and tasks of biological (cytogenetic) dosimetry in radiology are formulated

    A thermal neutron radiography system based on a compact 12 MeV superconducting proton cyclotron is described. Neutrons are generated using a thick beryllium target and moderated in high density polyethylene. Monte Carlo computer simulations have been used to model the neutron and photon transport in order to optimise the performance of the system. With proton beam currents in excess of 100 [mu]A, it can provide high thermal neutron fluxes with L/D ratios of between 50 and 300 for various applications. Both film and electronic imaging are used to produce radiographs. The electronic imaging system consists of a [sup 6]Li-loaded ZnS intensifier screen, and a low light CCD or SIT camera. High resolution images can be recorded and computer-controlled data processing, analysis and display are possible. ((orig.))

    Full Text Available Research on identification of honey bee using Computed Radiography has been done. The testing was carried out by providing digital radiograph of the three types of honey bee. The voltage of the x-ray generator was varied at 50 kV, 60 kV and 70 kV, while filament current was set at 100 mA and exposure time was at 5 ms. Honey bee was identified based on the image line profile that indicated the distribution of linear absorption coefficient (µ for each sample. The analyses on the image line profile showed that at the voltage of 50 kV and 70 kV the three kinds of the honey bee can be distinguished. However, at the voltage of 60 kV the difference among honey bee was unable to be identified.

    Computer simulation methods for determining patient dose from dental radiography have demonstrated that patient risk from a two-film interproximal examination ranges from 1.1 X 10(-8) to 3.4 X 10(-7) using 90-kVp beams, depending on film speed, projection technique, and age and sex of the patient. Further, changing from a short-cone round-beam to a long-cone technique with rectangular collimation reduces risk by a factor of 2.9, independent of other factors

    Recent years have brought rapid developments in computational image analysis in musculo-skeletal radiology. Meanwhile the algorithms have reached a maturity that makes initial clinical use feasible. Applications range from joint space measurement to erosion quantification, and from fracture detection to the assessment of alignment angles. Current results of computational image analysis in radiography are very promising, but some fundamental issues remain to be clarified, among which the definition of the optimal trade off between automatization and operator-dependency, the integration of these tools into clinical work flow and last not least the proof of incremental clinical benefit of these methods.

    Reasons for the variation in patient doses from chest radiography procedure were investigated by assessing entrance skin doses from kerma-area product measurements. Data were collected from seven x-ray tubes in five hospitals involving 259 adult patients. The third quartile value was 0.81 mGy compared to general reference level of 0.30 mGy. The applied tube potential was main contributor to patient dose variation. If department use at least 90 k Vp, the mean entrance surface dose would be reduced ut to factor six. Modification of departmental procedure is correct approach for dose reduction in diagnostic radiology. (author) [sr

    Introduction: The Faculty of Medicine, Makerere University is the oldest health professions training institution in East Africa having started in 1924. The radiography degree course started in 2001 and Makerere remains the only institution in the East African region offering this degree course. The faculty adopted a Problem based Learning/Community based education curriculum in order to stimulate students' interests to consider working in rural areas. Attracting and retaining radiographers and other health professionals in rural areas is a recognized problem in Uganda and overseas and strategic actions to enhance the rural health workforce and its ability to deliver the required services are paramount. A range of factors in different domains can be associated with recruitment and retention. By consulting students, some of these factors can be identified and addressed. Methodology: It was a descriptive exploratory study involving 31 students. Data was collected through a questionnaire and focus group discussions. Results: 58% of the students reported that they would consider rural radiography practice while 42% would not. Key motivational factors cited to work in rural areas were; attractive salaries/incentives, community based training curricular, opportunities for further training and well equipped rural health facilities. Conclusion: This study has shown that students would consider working in rural areas provided the working conditions are improved upon.

    Purpose: The purpose of this study was to gain an insight into radiography students' clinical practice experiences within an MRI unit of a large teaching hospital in Malta. The underlying objectives of the study were to identify and explore the descriptions and meanings of the MRI clinical experiences of students. Methods: Five students, independently undergoing their clinical placements in MRI were asked to write a diary about their daily experiences. Each student then participated in a follow up interview. Data analysis was based on Husserls' phenomenological approach. Results: Eight themes emerged from the data analysed. Students described their experience as one mainly based on observation, where, during their placements, they observed radiographers at work. In this respect, students described their experience as lacking ‘hands on practice’. Students indicated that they felt uncomfortable, unsupervised and unwelcome most of the time. They also expressed the need to feel useful and part of the MRI team during their placement and so they tried to help the team in areas such as patient screening. This helped them build confidence. Learning in MRI was specifically based on the university tasks prescribed and possibly there was no motivation to learn more. The students also described their experience as varied and different when compared to other placements. Conclusion: This study provides a rare insight into radiography students' placement experiences in MRI and should enable the supervising radiographer and educator to obtain a deeper appreciation of the clinical placement experience

    Sexuality education teachers' perspectives are important to gain a full understanding of the issues surrounding teaching this subject. This study uses a statewide sample of public school teachers to examine what sexuality education content is taught, what barriers teachers face, and which barriers are associated with teaching specific topics. Participants included 368 middle and high school teachers with sexuality education assignments in Minnesota. Survey data included topics they teach, what they think they should teach, and barriers they face. Logistic regression was used to examine associations between barriers and teaching each of 9 sexual health topics, among those who believed the topic should be taught. Almost two thirds of participants faced structural barriers; 45% were concerned about parent, student, or administrator response; and one quarter reported restrictive policies. Structural barriers were inversely associated with teaching about communication (OR = 0.20), teen parenting (OR = 0.34), and abortion (OR = 0.32); concerns about responses were associated only with teaching about sexual violence (OR = 0.42); and restrictive policies were inversely associated with teaching about abortion (OR = 0.23) and sexual orientation (OR = 0.47). Addressing teachers' barriers requires a multipronged approach, including curriculum development and evaluation, training, and reframing the policy debate to support a wider range of sexuality education topics. © 2013, American School Health Association.

    Manufacturers offer exposure indices as a safeguard against overexposure in computed radiography, but the basis for recommended values is unclear. This study establishes an optimum exposure index to be used as a guideline for a specific CR system to minimise radiation exposures for computed mobile chest radiography, and compares this with manufacturer guidelines and current practice. An anthropomorphic phantom was employed to establish the minimum milliamperes consistent with acceptable image quality for mobile chest radiography images. This was found to be 2 mAs. Consecutively, 10 patients were exposed with this optimised milliampere value and 10 patients were exposed with the 3.2 mAs routinely used in the department of the study. Image quality was objectively assessed using anatomical criteria. Retrospective analyses of 717 exposure indices recorded over 2 months from mobile chest examinations were performed. The optimised milliampere value provided a significant reduction of the average exposure index from 1840 to 1570 (p<0.0001). This new ''optimum'' exposure index is substantially lower than manufacturer guidelines of 2000 and significantly lower than exposure indices from the retrospective study (1890). Retrospective data showed a significant increase in exposure indices if the examination was performed out of hours. The data provided by this study emphasise the need for clinicians and personnel to consider establishing their own optimum exposure indices for digital investigations rather than simply accepting manufacturers' guidelines. Such an approach, along with regular monitoring of indices, may result in a substantial reduction in patient exposure. (orig.)

    Plain films and direct magnification radiographs of the hands were performed in 34 patients affected by rheumatoid arthritis, using mammographic x-ray tube, achieved with 0.1 mm microfocus, and 1.85 x magnification factor. Direct magnification radiography has provided essential or useful diagnostic data in 44% of cases, particularly in recognizing early skeletal erosions. Nevertheless direct magnification radiography must be used only in those cases in which traditional mammographic techniques do not supply sactisfactory results.

    Dental emergencies often present to primary care providers in general practice and Emergency Departments (ED), who may be unable to manage them effectively due to limited knowledge, skills and available resources. This may impact negatively on patient outcomes. Provision of a short educational workshop intervention in the management of such emergencies, including education in supporting resources, may provide a practical strategy for assisting clinicians to provide this aspect of comprehensive primary care. This descriptive study used a validated questionnaire survey instrument to measure the effectiveness of a short multimodal educational intervention through the uptake and perceived usefulness of supporting resources at 6 months following the intervention. Between 2009 and 2010, 15 workshops, of which eight were for regional and rural hospital ED doctors, were conducted by the same presenter using the same educational materials and training techniques. A sample of 181 workshop participants, 63% of whom were in rural or remote practice and engaged in providing primary care medical services, returned responses at 6 months on the perceived usefulness of the dental emergencies resource. Thirty percent of clinicians had used the dental emergencies resource within the six-month follow-up period. Significance was demonstrated between professional category and use of the resource, with emergency registrars utilising this resource most and GPs the least. The Dental Handbook, specifically designed for ED use, and tooth-filling material contained within this resource, were deemed the most useful components. There were overall positive open-ended question responses regarding the usefulness of the resource, especially when it was made available to clinicians who had attended the education workshops. Utilisation and perceived usefulness of a supporting resource at 6 months are indicators of the effectiveness of a short workshop educational intervention in the management of

    Compton radiography provides a means to measure the integrity, ρR and symmetry of the DT fuel in an inertial confinement fusion implosion near peak compression. Upcoming experiments at the National Ignition Facility will use the ARC (Advanced Radiography Capability) laser to drive backlighter sources for Compton radiography experiments and will use the newly commissioned AXIS (ARC X-ray Imaging System) instrument as the detector. AXIS uses a dual-MCP (micro-channel plate) to provide gating and high DQE at the 40–200 keV x-ray range required for Compton radiography, but introduces many effects that contribute to the spatial resolution. Experiments were performed at energies relevant to Compton radiography to begin characterization of the spatial resolution of the AXIS diagnostic.

    General Atomics (GA) is under contract to construct a Stationary Neutron Radiography System (SNRS) - on a turnkey basis - at McClellan Air Force Base in Sacramento, California. The SNRS is a custom designed neutron radiography system which will utilize a 1000 KW TRIGA reactor as the neutron source. The partially below-ground reactor will be equipped with four inclined beam tubes originating near the top of the reactor graphite reflector and installed tangential to the reactor core to provide a strong current of thermal neutrons with minimum gamma ray contamination. The inclined beam tubes will terminate in four large bays and will interface with rugged component positioning systems designed to handle intact aircraft wings, other honeycomb aircraft structures, and pyrotechnics. The SNRS will be equipped with real-time, near real-time, and film radiographic imaging systems to provide a broad spectrum of capability for detection of entrained moisture or corrosion in large aircraft panels. GA is prime contractor to the Air Force for the SNRS and is specifically responsible for the TRIGA reactor system and a portion of the neutron beam system design. Science Applications International Corporation and the Lionakis-Beaumont Design Group are principal subcontractors to GA on the project. (author)

    2003-12-01

    Undergraduate major enrollments in the Department of Geosciences at Penn State have held steady over the past 5 years despite generally declining national trends. We have successfully recruited and retained new students through intensive advising coupled with innovative curricular revision aimed to meet an array of students' educational and career goals. Our focus is on degree programs that reflect emerging interdisciplinary trends in both employment and student interest, and are designed to attract individuals from underrepresented groups. In addition to a traditional Geosciences BS program we offer a rigorous integrated Earth Sciences BS and a Geosciences BA tailored to students with interests in education and environmental law. The Earth Sciences BS incorporates course work from Geosciences, Geography and Meterology, and requires completion of an interdisciplinary minor (e.g., Climatology, Marine Sciences, Global Business Strategies). A new Geobiology BS program will attract majors with interests at the intersection of the earth and life sciences. The curriculum includes both paleontological and biogeochemical coursework, and is also tailored to accommodate pre-medicine students. We are working actively to recruit African-American students. A new minor in Science and Technology in Africa crosses disciplinary boundaries to educate students from the humanities as well as sciences. Longitudinal recruitment programs include summer research group experiences for high school students, summer research mentorships for college students, and dual undergraduate degree programs with HBCUs. Research is a fundamental component of every student's degree program. We require a capstone independent thesis as well as a field program for Geosciences and Geobiology BS students, and we encourage all students to pursue research as early as the freshman year. A new 5-year combined BS-MS program will enable outstanding students to carry their undergraduate research further before

    The image quality of dual-reading computed radiography and dose-reduced direct radiography of the chest was compared in a clinical setting. The study group consisted of 50 patients that underwent three posteroanterior chest radiographs within minutes, one image obtained with a dual read-out computed radiography system (CR; Fuji 5501) at regular dose and two images with a flat panel direct detector unit (DR; Diagnost, Philips). The DR images were obtained with the same and with 50% of the dose used for the CR images. Images were evaluated in a blinded side-by-side comparison. Eight radiologists ranked the visually perceivable difference in image quality using a three-point scale. Then, three radiologists scored the visibility of anatomic landmarks in low and high attenuation areas and image noise. Statistical analysis was based on Friedman tests and Wilcoxon rank sum tests at a significance level of P<0.05. DR was judged superior to CR for the delineation of structures in high attenuation areas of the mediastinum even when obtained with 50% less dose (P<0.001). The visibility of most pulmonary structures was judged equivalent with both techniques, regardless of acquisition dose and speed level. Scores for image noise were lower for DR compared with CR, with the exception of DR obtained at a reduced dose. Thus, in this clinical preference study, DR was equivalent or even superior to the most modern dual read-out CR, even when obtained with 50% dose. A further dose reduction does not appear to be feasible for DR without significant loss of image quality. (orig.)

  7. Optimizing digital radiography of children

    2009-01-01

    Pediatric projection imaging differs from imaging of the adult patient. Children are smaller, more radiosensitive, and less compliant than their adult counterparts. Their characteristics affect the way projection imaging is practiced and how dose is optimized. Computed radiography (CR) and digital radiography (DR) have been embraced by pediatric practitioners in order to reduce dose and improve image quality. Unfortunately, dose optimization with CR and DR has been hampered by a lack of definition of appropriate exposure levels, a lack of standardization in exposure factor feedback, and a lack of understanding of the fundamentals of CR and DR technology. The potential for over-exposure exists with both CR and DR. Both the Society for Pediatric Radiology and the American Association of Physicists in Medicine recognize the promise and shortcomings of CR and DR technology and have taken steps to join with manufacturers in improving the practice of CR and DR imaging. Although the risks inherent in pediatric projection imaging with CR and DR are low, efforts to reduce dose are worthwhile, so long as diagnostic quality is maintained. Long-standing recommendations for limiting radiation dose in pediatric projection imaging are still applicable to CR and DR.

    A directory of neutron radiography facilities around the world was informally compiled about ten years ago under the auspices of the American Society for Testing and Materials (ASTM), Subcommittee E7.05 (Radiology, Neutron). The work lay dormant for a number of years, but was revived in earnest in the fall of 1995. At that time, letters were mailed to all the facilities with available addresses in the original directory, requesting updated information. Additionally, information was gathered at the Second Topical meeting on neutron Radiography Facility System Design and Beam Characterization (November, 1995, Shonan Village, Japan). A second mailing was sent for final confirmation and updates in January, 1996. About 75% of the information in the directory has now been confirmed by the facility management. This paper presents a summary of the information contained in the facility directory. An electronic version of the directory in Wordperfect 6.1, uuencode, or rtf format is available by sending e-mail to the authors at imel at sign anl.gov or imel at sign baobab.cad.cea.fr.

    The digital radiographic image became a reality as of the 80's decade. Since then, several works have been developed with the aim of reducing the exposure time to ionizing radiation obtaining in this way an excellent image quality with a minimum exposure. In the Computerized Radiography, the conventional film is substituted for Image Plate (IP) which consists of a radiosensitive layer of phosphor crystals on a polyester backing plate. The unique design makes it reusable and easy to handle. When exposed, the IP accumulates and stores the irradiated radioactive energy. In order to qualify a computerized radiography system it is necessary to evaluate the Image Plate. In this work it was performed a series of experimental procedures with the aim of evaluating the responses characteristics for different plates. For this purpose it was used a computerized radiographic system CR Tower Scanner - GE, with three different types of IPs, all of them manufactured by GE, whose nomenclatures are IPC, IPX and IPS. It was used the Rhythm Acquire and Review programs for image acquisition and treatment, respectively. (author)

    All personnel present in the X-ray examination room during equine radiography were monitored using low energy direct reading ionization chambers (pockets dosimeters) worn outside the lead apron at neck level. The individuals' task and dosimeter readings were recorded after each examination. Average doses ranged from 0 to 6 mrad per study. The greatest exposures were associated with radiography of the shoulder and averaged less than 4 mrad. The individual extending the horse's limb was at greatest risk although the individual holding the horse's halter and the one making the X-ray exposure received similar exposures. A survey of the overhead tube assembly used for some of the X-ray examinations also was performed. Meter readings obtained indicated an asymetric dose distribution around the tube assembly, with the highest dose occurring on the side to which the exposure cord was attached. Although the exposures observed were within acceptable limits for occupational workers, we have altered our protocol and no longer radiograph the equine shoulder unless the horse is anesthetized. Continued use of the pocket dosimeters and maintenance of a case record of radiation exposure appears to make the technologists more aware of radiation hazards

    During radiography of the carpus of horses calcium fluoride thermoluminescent dosemeters were used to measure the radiation exposure to the hand of an assistant positioning the x-ray film. Three portable x-ray machines and a mobile machine were used during the recordings. The effects of x-ray machine, radiographic technique, and lead rubber gloves upon radiation exposure to the hand were investigated. The size of the primary beam of the x-ray machine was found to be the major factor in determining the dose of radiation received by the hand. The highest radiation exposures were recorded when using two portable machines which were fitted with beam limiting devices that permitted only one primary beam size. The lowest exposures were measured when radiographs were taken with the mobile machine that was fitted with a light beam diaphragm. The control of primary beam size with a light beam diaphragm was found to be the most effective method of reducing radiation dosage to the hand. It is strongly recommended that for equine radiography a light beam diaphragm be fitted to and used on all x-ray machines, and a cassette holder be used to keep the hands out of the primary beam.

    The manifold increase in production, and ease of availability of radioisotopes in India have been responsible for a tremendous increase in use of radioisotopes in industrial radiography during past fifteen years. Among various applications of radioisotopes the industrial radiography involves a large potential risk of occupational radiation exposures. The dose records of past fifteen years in respect of all radiation workers maintained by the Personnel Monitoring Group of Division of Radiological Protection of the Bhabha Atomic Research Centre, Bombay, have been analysed. Analysis of excessive exposure (exceeding 400 mrem/fortnight) reveals that this figure is increasing at an alarming rate among the radiation workers of this category. In spite of various regulatory controls the dose per person per week has remained higher as compared to the same in other categories. This combined with the increase in number of radiation workers every year would soon contribute significantly to the per capita dose for radiation workers. Use of adequately shielded fool-proof remote control equipment and training of all personnel in safe handling of radiation sources seem to be the only solution to arrest the rate of increase in personnel exposures of this category.

    Potential non-physician anesthesia students gauge many different aspects of a graduate program prior to applying, but cost of education and earning potential are typically high priorities for students. Our analysis evaluated the cost of tuition for all certified registered nurse anesthetist (CRNA) and anesthesiologist assistant (AA) programs in the United States, as well as earning potential for both professions. We collected educational cost data from school websites and salary data from the Medical Group Management Association's Physician Compensation and Production Survey: 2012 Report in order to compare the two groups. We found that the median cost of public CRNA programs is $40,195 and the median cost of private programs is $60,941, with an overall median of $51,720. Mean compensation for CRNAs in 2011 was $156,642. The median cost of public AA programs is $68,210 compared with $77,155 for private AA education, and an overall median cost of $76,037. Average compensation for AAs in 2011 was $123,328. Considering these factors, nurse anesthesia school is a better choice for candidates who already possess a nursing license; however, for those prospective students who are not nurses, AA school may be a more economical choice, depending on the type and location of practice desired.

    Neutron imaging became important when, besides providing impressive radiographic and tomographic images of various objects, physical, quantification of chemical, morphological or other parameters could be derived from 2D or 3D images. The spatial resolution of approximately 50 µm (and less) yields real space images of the bulk of specimens with more than some cm 3 in volume. Thus the physics or chemistry of structures in a sample can be compared with scattering functions obtained e.g. from neutron scattering. The advantages of using neutrons become more pronounced when the neutron spin comes into play. The interaction of neutrons with magnetism is unique due to their low attenuation by matter and because their spin is sensitive to magnetic fields. Magnetic fields, domains and quantum effects such as the Meissner effect and flux trapping can only be visualized and quantified in the bulk of matter by imaging with polarized neutrons. This additional experimental tool is gaining more and more importance. There is a large number of new fields that can be investigated by neutron imaging, not only in physics, but also in geology, archeology, cultural heritage, soil culture, applied material research, magnetism, etc. One of the top applications of polarized neutron imaging is the large field of superconductivity where the Meissner effect and flux pinning can be visualized and quantified. Here we will give a short summary of the results achieved by radiography and tomography with polarized neutrons. - Highlights: • Radiography and tomography with polarized neutrons yield new results concerning the suppressed Meissner effect and magnetic flux trapping. • Suppressed Meissner effect was observed in pure lead samples and niobium. • Trapped magnetic fields in cylindrical Pb samples are squeezed around the rod axis. • The shape and the amount of trapped fields could be determined and quantified

    1982-01-01

    The Californium Multiplier (CFX) is a subcritical assembly of enriched uranium surrounding a californium-252 neutron source. The function of the CFX is to multiply the neutrons emitted by the source to a number sufficient for neutron radiography. The CFX is designed to provide a collimated beam of thermal neutrons from which the gamma radiation is filtered, and the scattered neutrons are reduced to make it suitable for high resolution radiography. The entire system has inherent safety features, which provide for system and personnel safety, and it operates at moderate cost. In Part I, the CFX and the theory of its operation are described in detail. Part II covers the performance of the Mound Facility CFX

    The fast neutron radiography enables us to image extended objects and yields quite different pictures than conventional roentgenograms. Using foils of cellulose nitrate and the track etching technique a γ-ray-insensitive detector is available providing sufficient imaging qualities. One of the biological neutrograms shown in the paper is of special importance because one can see a malignant tumor of the columna vertebralis. This finding was not detectable by roentgenological examination. (orig.) [de

    To achieve a quality neutron radiographic image in a relatively short exposure time, the neutron radiography beam must be of good quality and relatively high neutron flux. Characterization of a neutron radiography beam, such as determination of the image quality and the neutron flux, is vital for producing quality radiographic images and also provides a means to compare the quality of different neutron radiography facilities. This paper provides a characterization of the radial and tangential neutron radiography beamlines at the Tehran research reactor. This work includes determination of the facilities category according to the American Society for Testing and Materials (ASTM) standards, and also uses the gold foils to determine the neutron beam flux. The radial neutron beam is a Category I neutron radiography facility, the highest possible quality level according to the ASTM. The tangential beam is a Category IV neutron radiography facility. Gold foil activation experiments show that the measured neutron flux for radial beamline with length-to-diameter ratio (L/D) =150 is 6.1× 10 6 n cm −2 s −1 and for tangential beamline with (L/D)=115 is 2.4× 10 4 n cm −2 s −1 .

  5. Digital radiography is promising in industrial testing

    International Nuclear Information System (INIS)

    Del Fabbro, F.

    2015-01-01

    Digital radiography has recently entered the industrial world as a tool for non-destructive testing. There are 3 types of digital radiography: computed radiography (CR), direct radiography (DR) and computed tomography (CT). In computed radiography, traditional silver-halide films are replaced by photostimulable phosphor imaging plates that are activated through laser scanning and digitized. Direct radiography uses a flat panel detector (FPD) composed of X-ray detectors that performs an immediate digital conversion of the image that can be read by a computer. DR is a perfect tool for industrial testing but the fragility of the FPD panels reduces its uses. Computed tomography is based on the principle of DR to get data corresponding to successive cross-section images of the object. These data are processed by a software to get a 3-dimensional image of the object. CT was first developed for medical use but requires some improvement to become more accurate, faster, particularly for big objects. In recent years DR has enjoyed the highest growth rate in digital radiography. (A.C.)

    Due to many adverse health effects, victims of domestic violence are frequently seen in the health care system. Yet, health care providers may lack the training to assist them. Online curricula can be an effective instructional tool. Our competency-based, serious video game, Responding to Domestic Violence in Clinical Settings, was designed to address health care providers' knowledge gaps through 17 modules, each a half hour in length. Nearly 9,000 participants completed at least one module; nursing students completed the most modules, approximately five hours of instruction. This serious video game-based curriculum is useful in helping health providers and students learn about Domestic Violence.

  7. Proton radiography using highpower femtosecond laser

    2010-08-01

    A femtosecond laser emits pulses whose width is between few and few hundreds femtoseconds (10 -15 s). The production mechanism of the high energy protons generated by the femtosecond laser is not clear so far, but the technologies have been improving. The applications using the generated protons are the proton therapy, proton radiography, nuclear physics, security inspection, and so on. Especially in the radiography, the laser-generated protons are very useful to obtain high quality images of thin objects, because protons are able to penetrate an object following an almost straight path and give a depth distribution information of various elements in a subject. Since the laser-driven protons require lower cost and smaller facility than accelerator-based protons, the radiography using laser-driven protons have been of interest. In this research, we have performed the radiography experiments by using protons generated by the 100 TW titanium sapphire femtosecond laser facility of Advanced Photonics Research Institute (APRI) of Gwangju Institute of Science Technology (GIST). A CR-39 Solid State Nuclear Track Detector (SSNTD) has been used as radiography screen. The radiography digital images have been obtained by using an optical microscope and a CCD camera. Modulation Transfer Function (MTF) has been derived from analyzing the obtained images, and the spatial resolution of the images have been evaluated. And, we have performed the radiography experiments of monoenergetic proton from the Tandem Van de Graaff accelerator of Korea Institute of Geoscience and Mineral Resources (KIGAM). We have obtained and compared the radiography images from other proton production methods which are the laser and the accelerator, respectively. And also, we have found out the optimized chemical etching condition, in order to improve the spatial resolution of the radiography images. Finally, the evaluated maximum spatial resolution of the images are 2.09 μm

    The use of charged particles for radiographic applications has been considered for some time, but progress has been impeded by the cost and availability of suitable accelerators. However, recent developments in technology could overcome these problems. A review is presented of the physical principles leading to an improvement in mass resolution per unit of absorbed dose for charged particle radiography relative to x-ray radiography. The quantitative comparisons between x-ray and proton radiographs presented here confirm this advantage. The implications of proton radiography on cancer detection, as well as future plans for developing a proton tomographic system, are discussed

    The results of chest radiography in 581 patients with blunt minor thoracic trauma were reviewed. Frontal and lateral views of the chest indicated pathology in 72 patients (12.4%). Pneumothorax was present in 16 patients; 4 had hemothorax. The physical examination and the results of chest radiography were not in accordance because in 6(30%) of the 20 patients with hemo/-pneumothorax the physical examination was normal. Consequently there is wide indication for chest radiography after minor blunt chest trauma. (orig.)
