Perspectives on program duration and research: A survey of graduates of a 3-year medical physics residency program.

PURPOSE: The goal of this manuscript is to evaluate strengths and weaknesses of a 3-year medical physics residency program with the first year dedicated to research and the remaining 2 years dedicated to clinical training. METHODS: An anonymous survey was distributed to graduates of a 3-year medical physics residency program with a dedicated year of research. Questions focused on several categories: (1) in retrospect, factors graduates considered at the time of application, (2) aspects of respondents' career and life after graduating from residency, (3) respondents' opinions on the residency duration, and (4) research productivity during residency. RESULTS: Of 22 graduates who were contacted, 17 filled out the survey. In retrospect, the most impactful consideration at the time of application was quality of clinical training. Extra time for research was reported as the factor with the most positive career impact and financial considerations as the most negative impact of completing a 3-year residency. Preference for a 3-year residency at the time of application and in retrospect was expressed by 47% and 88% of respondents, respectively. 71% of respondents would recommend applying to a 3-year program to current residency candidates, and 29% respondents said their recommendation on entering a 3-year program would depend on the candidate's interests. 76% of respondents preferred dedicated time for research during residency. CONCLUSIONS: The optimal duration of medical physics residency depends on the goals and career objectives of the incoming residents. Two years may be an optimal duration for clinical training. For candidates interested in a career with a substantial research component, a 3-year program may be a good option, and graduates express favorable opinions after completing such a program. A 4-year residency duration is not viewed favorably by the graduates.

Implementation of a programmatic assessment model in radiation oncology medical physics training.

PURPOSE: In 2019, a formal review and update of the current training program for medical physics residents/registrars in Australasia was conducted. The purpose of this was to ensure the program met current local clinical and technological requirements, to improve standardization of training across Australia and New Zealand and generate a dynamic curriculum and programmatic assessment model. METHODS: A four-phase project was initiated, including a consultant desktop review of the current program and stakeholder consultation. Overarching program outcomes on which to base the training model were developed, with content experts used to update the scientific content. Finally, assessment specialists reviewed a range of assessment models to determine appropriate assessment methods for each learning outcome, creating a model of programmatic assessment. RESULTS: The first phase identified a need for increased standardized assessment incorporating programmatic assessment. Seven clear program outcome statements were generated and used to guide and underpin the new curriculum framework. The curriculum was expanded from the previous version to include emerging technologies, while removing previous duplication. Finally, a range of proposed assessments for learning outcomes in the curriculum were generated into the programmatic assessment model. These new assessment methods were structured to incorporate rubric scoring to provide meaningful feedback. CONCLUSIONS: An updated training program for Radiation Oncology Medial Physics registrars/residents was released in Australasia. Scientific content from a previous program was used as a foundation and revised for currency with the ability to accommodate a dynamic curriculum model. A programmatic model of assessment was created after comprehensive review and consultation. This new model of assessment provides more structured, ongoing assessment throughout the training period. It contains allowances for local bespoke assessment, and guidance for supervisors by the provision of marking templates and rubrics.

A comparison of three-film analysis software for stereotactic radiotherapy patient-specific quality assurance.

AIM: The aim of this study was to investigate the suitability of three radiochromic film analysis software for stereotactic radiotherapy patient-specific quality assurance (PSQA): FilmQA Pro v5.0, SNC Patient v6.2, and eFilmQA v5.0. METHODS: Film calibration was conducted for each software followed by three sets of measurements. The first set assessed calibration accuracy by comparing measured and delivered doses at increments different from those used for calibration. The second set used each software to conduct PSQA through gamma analysis on 10 stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT) patients. The third set utilized SNC Patient and eFilmQA to carry out gamma analysis on a collection of four digital test images, eliminating delivery and scanning uncertainties from impacting the analysis. Key supporting features within each software for conducting gamma analysis were identified. RESULTS: Overall, FilmQA Pro and eFilmQA were deemed comparable and favoured over SNC Patient due to the presence of key features such as triple-channel dosimetry, auto-optimization, and dose scaling. FilmQA Pro has a substantial user base and established reputation. eFilmQA, having been introduced more recently, serves as a viable alternative to FilmQA Pro, having been further refined for stereotactic radiotherapy PSQA. CONCLUSION: This study investigated the suitability of three film analysis software (FilmQA Pro, eFilmQA, and SNC Patient) for stereotactic radiotherapy PSQA. Results from the investigation indicated that both FilmQA Pro and eFilmQA are comparably suitable and are preferred over SNC Patient. Both FilmQA Pro and eFilmQA are recommended for radiotherapy clinics.

Clinician's guide to the basic principles of MRI.

MRI is an important and widely used imaging modality for clinical diagnosis. This article provides a concise discussion of the basic principles of MRI physics for non-radiology clinicians, with a general explanation of the fundamentals of signal generation and image contrast mechanisms. Common pulse sequences, tissue suppression techniques and use of gadolinium contrast with relevant clinical applications are presented. Knowledge of these concepts would provide an appreciation of how MR images are acquired and interpreted to facilitate interdisciplinary understanding between radiologists and referring clinicians.

Combined clinical and research training in medical physics in a multi-institutional setting: 13-year experience of Harvard Medical Physics Residency Program.

PURPOSE: This manuscript describes the structure, management and outcomes of a multi-institutional clinical and research medical physics residency program (Harvard Medical Physics Residency Program, or HMPRP) to provide potentially useful information to the centers considering a multi-institutional approach for their training programs. METHODS: Data from the program documents and public records was used to describe HMPRP and obtain statistics about participating faculty, enrolled residents, and graduates. Challenges associated with forming and managing a multi-institutional program and developed solutions for effective coordination between several clinical centers are described. RESULTS: HMPRP was formed in 2009 and was accredited by the Commission on Accreditation of Medical Physics Education Programs (CAMPEP) in 2011. It is a 3-year therapy program, with a dedicated year of research and the 2 years of clinical training at three academic hospitals. A CAMPEP-accredited Certificate Program is embedded in HMPRP to allow enrolled residents to complete a formal didactic training in medical physics if necessary. The clinical training covers the material required by CAMPEP. In addition, training in protons, CyberKnife, MR-linac, and at network locations is included. The clinical training and academic record of the residents is outstanding. All graduates have found employment within clinical medical physics, mostly at large academic centers and graduates had a 100% pass rate at the oral American Board of Radiology exams. On average, three manuscripts per resident are published during residency, and multiple abstracts are presented at conferences. CONCLUSIONS: A multi-institutional medical physics residency program can be successfully formed and managed. With a collaborative administrative structure, the program creates an environment for high-quality clinical training of the residents and high productivity in research. The main advantage of such program is access to a wide variety of resources. The main challenge is creating a structure for efficient management of multiple resources at different locations. This report may provide valuable information to centers considering starting a multi-institutional residency program.

Overview of medical physics education and research programs in a non-academic environment.

Northwest Medical Physics Center (NMPC) is a nonprofit organization that provides clinical physics support to over 35 radiation therapy facilities concentrated in the Pacific Northwest. Although clinical service is the primary function of NMPC, the diverse array of clinical sites and physics expertise has allowed for the establishment of structured education and research programs, which are complementary to the organization's clinical mission. Three clinical training programs have been developed at NMPC: a therapy medical physics residency program accredited by the Commission on Accreditation of Medical Physics Education Programs (CAMPEP), an Applied Physics Technologist (APT) program, and a summer undergraduate internship program. A partnership has also been established with a major radiation oncology clinical vendor for the purposes of validating and testing new clinical devices across multiple facilities. These programs are managed by a dedicated education and research team at NMPC, made up of four qualified medical physicists (QMPs). The education and research work has made a significant contribution to the organization's clinical mission, and it has provided new training opportunities for early-career physicists across many different clinical environments. Education and research can be incorporated into nonacademic clinical environments, improving the quality of patient care, and increasing the number and type of training opportunities available for medical physicists.

Education case report: CAMPEP Medical Physics PhD education program within Engineering.

Medical physics doctoral programs have large variations in organization, administration and financing. Blending a medical physics stream into an engineering graduate program has advantages of pre-existing financial and educational infrastructures. A case study of the accredited program at Dartmouth was carried out, analyzing operational, financial, educational and outcome features. The support structures provided by each institutional partner were outlined, including engineering school, graduate school, and radiation oncology. The initiatives undertaken by founding faculty were reviewed, along with allocated resources, financial model, and peripheral entrepreneurship activities, each with quantitative outcome metrics. Currently 14 PhD students are enrolled, supported by 22 faculty across both engineering and clinical departments. The total peer-reviewed publications are ≈75/year, while the conventional medical physics fraction of this is about 14/year. Following program formation, a significant rise was seen in jointly published papers between engineering and medical physics faculty, up from 5.6 to 13.3 papers/year, with students publishing an average of 11.3/person with 5.7/person as first author. Student support was predominantly via federal grants, with a stable $5.5million/year, using about $610K/year supporting student stipends and tuition. First year funding, recruiting and staff support were via engineering school. Faculty teaching effort was supported by agreement with each home department, and student services were provided by engineering and graduate schools. Student outcomes were exceptional, with high numbers of presentations, awards, and residency placements at research universities. The lack of financial and student support in medical physics can be mitigated by this hybrid design of blending medical physics doctoral students into an engineering graduate program, providing complementary strengths. Future growth in medical physics programs might consider following this pathway, strengthening research collaborations for clinical physics and engineering faculty, as long as there is vested commitment to teach by the faculty and department leadership.

Quality management, quality assurance, and quality control in medical physics.

The historic and ongoing evolution of the practice, technology, terminology, and implementation of programs related to quality in the medical radiological professions has given rise to the interchangeable use of the terms Quality Management (QM), Quality Assurance (QA), and Quality Control (QC) in the vernacular. This White Paper aims to provide clarification of QM, QA, and QC in medical physics context and guidance on how to use these terms appropriately in American College of Radiology (ACR) Practice Parameters and Technical Standards, generalizable to other guidance initiatives. The clarification of these nuanced terms in the radiology, radiation oncology, and nuclear medicine environments will not only boost the comprehensibility and usability of the Medical Physics Technical Standards and Practice Parameters, but also provide clarity and a foundation for ACR's clinical, physician-led Practice Parameters, which also use these important terms for monitoring equipment performance for safety and quality. Further, this will support the ongoing development of the professional practice of clinical medical physics by providing a common framework that distinguishes the various types of responsibilities borne by medical physicists and others in the medical radiological environment. Examples are provided of how QM, QA, and QC may be applied in the context of ACR Practice Parameters and Technical Standards.

Equity, diversity, and inclusion topics at a medical physics residency journal club.

A journal club program was initiated in a clinically focused, geographically distributed medical physics therapy residency program. This program currently supports two residents at different clinical sites, who regularly present at the new journal club. For one of the sessions, residents were assigned to present on topics related to the broad themes of equity, diversity, and inclusion (EDI) in the context of medical physics, radiation oncology, or medical oncology. As in other journal club sessions, residents were responsible for choosing their respective articles within required criteria and with approval from the program director. The session was executed in late 2022, with both residents leading and facilitating discussion for the residents, the residency program director, and all residency faculty members. This education case report will include the learning objectives for the journal club session, a description of the content covered in the session, discussion regarding the session's alignment with the original learning objectives, and ideas for program directors intending to include evidence-based EDI topics in journal clubs.

Virtual interviewing in the MedPhys match: Experiences of applicants and programs.

PURPOSE: The purpose of this survey study is to compare the experiences of programs and applicants in the MedPhys Match (MPM) in the 2020-21 match cycle with experiences reported from previous match cycles. The 2020-21 match cycle was unique in that recruitment and interviewing were almost exclusively virtual during the COVID-19 pandemic. METHODS: A survey was sent to all applicants and programs registered for the 2020-21 MPM. Survey questions asked about the pre-interview screening, interview, ranking, and post-match stages of the residency match process. Survey data were analyzed using graphical methods and spreadsheet tools. RESULTS: Advantages and disadvantages to the virtual interviewing experience were reported by applicants and program directors (PDs). The advantages included reduced cost and greater scheduling flexibility with fewer scheduling conflicts, allowing applicants to consider more programs. These advantages greatly outweighed the disadvantages such as the inability to meet faculty/staff and current residents in person and gauge the feel of the program. PDs recognized the advantages of minimal costs and time savings for applicants. Programs reported it was difficult to convey workplace culture and the physical environment and to gauge personality and interpersonal skills of the applicants. CONCLUSION: The virtual interviewing environment for residency recruitment in medical physics is strongly preferred by applicants over required in-person interviews. The advantages identified by applicants outweigh the disadvantages, allowing applicants to feel confident in their ranking decisions and overall satisfied with their match results. PDs acknowledge the greater equity of access to interviews for applicants in the virtual environment, however, they are overall less satisfied with their ability to showcase their program's strengths and to assess the personality of applicants. Caution is urged when considering a hybrid interview model to ensure fair assessments that do not depend on whether an applicant chooses to accept an optional in-person interview or site visit.

Radiation safety of current European practices of therapeutic nuclear medicine: survey results from 20 HERCA countries.

The purpose of this study was to acquire up-to-date information on nuclear medicine treatments in Europe and on the implementation of the requirements of the Basic Safety Standards Directive in HERCA Heads of the European Radiological Protection Competent Authorities (HERCAs) member states. An electronic survey was distributed to competent authorities of 32 HERCA member states. The questionnaire addressed 33 explicitly considered treatments using 13 different radionuclides, and for each treatment, a similar set of questions was included. Questions covered the use of treatments, hospitalisation of patients and radioactive waste management related to therapeutic nuclear medicine involving other radionuclides than the well-known131I. The survey also covered justification of treatments, individual treatment planning, involvement of a medical physics expert (MPE) and radiation protection instructions given to the patient at the time of release. Responses were obtained from 20 HERCA countries. All of these countries used Na[131I]I for benign thyroid diseases and thyroid ablation of adults. 223RaCl2(Xofigo®) for bone metastases,177Lu-somatostatin analogues for neuroendocrine tumours and177Lu-labelled PSMA for castration resistant prostate cancer (PC) and PC-metastases were used in 90%, 65% and 55% of countries, respectively. Only a few countries had specific criteria for hospitalisation and waste management for new therapeutic nuclear medicine. Regulatory requirements for justification of new therapeutic nuclear medicine were in place in almost all countries. Individual treatment planning was required for all therapies in 55% and for some therapies in 28% of the responding countries. Implementation of the requirement for MPEs to be closely involved in nuclear medicine practices varied to a great extend among countries. Almost all responding countries answered that some radiation protection instructions existed for patients released after treatment with radionuclides other than131I treatment, however only few countries had developed specific guidelines in the field.

Comparison of low-contrast detectability between uniform and anatomically realistic phantoms-influences on CT image quality assessment.

OBJECTIVES: To evaluate the effects of anatomical phantom structure on task-based image quality assessment compared with a uniform phantom background. METHODS: Two neck phantom types of identical shape were investigated: a uniform type containing 10-mm lesions with 4, 9, 18, 30, and 38 HU contrast to the surrounding area and an anatomically realistic type containing lesions of the same size and location with 10, 18, 30, and 38 HU contrast. Phantom images were acquired at two dose levels (CTDIvol of 1.4 and 5.6 mGy) and reconstructed using filtered back projection (FBP) and adaptive iterative dose reduction 3D (AIDR 3D). Detection accuracy was evaluated by seven radiologists in a 4-alternative forced choice experiment. RESULTS: Anatomical phantom structure impaired lesion detection at all lesion contrasts (p < 0.01). Detectability in the anatomical phantom at 30 HU contrast was similar to 9 HU contrast in uniform images (91.1% vs. 89.5%). Detection accuracy decreased from 83.6% at 5.6 mGy to 55.4% at 1.4 mGy in uniform FBP images (p < 0.001), whereas AIDR 3D preserved detectability at 1.4 mGy (80.7% vs. 85% at 5.6 mGy, p = 0.375) and was superior to FBP (p < 0.001). In the assessment of anatomical images, superiority of AIDR 3D was not confirmed and dose reduction moderately affected detectability (74.6% vs. 68.2%, p = 0.027 for FBP and 81.1% vs. 73%, p = 0.018 for AIDR 3D). CONCLUSIONS: A lesion contrast increase from 9 to 30 HU is necessary for similar detectability in anatomical and uniform neck phantom images. Anatomical phantom structure influences task-based assessment of iterative reconstruction and dose effects. KEY POINTS: • A lesion contrast increase from 9 to 30 HU is necessary for similar low-contrast detectability in anatomical and uniform neck phantom images. • Phantom background structure influences task-based assessment of iterative reconstruction and dose effects. • Transferability of CT assessment to clinical imaging can be expected to improve as the realism of the test environment increases.

AAPM Task Group 298: Recommendations on certificate program/alternative pathway candidate education and training.

Entry into the field of clinical medical physics is most commonly accomplished through the completion of a Commission on Accreditation of Medical Physics Educational Programs (CAMPEP)-accredited graduate and residency program. To allow a mechanism to bring valuable expertise from other disciplines into clinical practice in medical physics, an "alternative pathway" approach was also established. To ensure those trainees who have completed a doctoral degree in physics or a related discipline have the appropriate background and didactic training in medical physics, certificate programs and a CAMPEP-accreditation process for these programs were initiated. However, medical physics-specific didactic, research, and clinical exposure of those entering medical physics residencies from these certificate programs is often comparatively modest when evaluated against individuals holding Master's and/or Doctoral degrees in CAMPEP-accredited graduate programs. In 2016, the AAPM approved the formation of Task Group (TG) 298, "Alternative Pathway Candidate Education and Training." The TG was charged with reviewing previous published recommendations for alternative pathway candidates and developing recommendations on the appropriate education and training of these candidates. This manuscript is a summary of the AAPM TG 298 report.

AAPM Report 373: The content, structure, and value of the Professional Doctorate in Medical Physics (DMP).

The Professional Doctorate in Medical Physics (DMP) was originally conceived as a solution to the shortage of medical physics residency training positions. While this shortage has now been largely satisfied through conventional residency training positions, the DMP has expanded to multiple institutions and grown into an educational pathway that provides specialized clinical training and extends well beyond the creation of additional training spots. As such, it is important to reevaluate the purpose and the value of the DMP. Additionally, it is important to outline the defining characteristics of the DMP to assure that all existing and future programs provide this anticipated value. Since the formation and subsequent accreditation of the first DMP program in 2009-2010, four additional programs have been created and accredited. However, no guidelines have yet been recommended by the American Association of Physicists in Medicine. CAMPEP accreditation of these programs has thus far been based only on the respective graduate and residency program standards. This allows the development and operation of DMP programs which contain only the requisite Master of Science (MS) coursework and a 2-year clinical training program. Since the MS plus 2-year residency pathway already exists, this form of DMP does not provide added value, and one may question why this existing pathway should be considered a doctorate. Not only do we, as a profession, need to outline the defining characteristics of the DMP, we need to carefully evaluate the potential advantages and disadvantages of this pathway within our education and training infrastructure. The aims of this report from the Working Group on the Professional Doctorate Degree for Medical Physicists (WGPDMP) are to (1) describe the current state of the DMP within the profession, (2) make recommendations on the structure and content of the DMP for existing and new DMP programs, and (3) evaluate the value of the DMP to the profession of medical physics.

Introductory patient communication training for medical physics graduate students: Pilot experience.

Despite medical physics becoming a more patient-facing part of the radiation oncology team, medical physics graduate students have no training in patient communication. An introductory patient communication training for medical physics graduate students is presented here. This training exposes participants to foundational concepts and effective communication skills through a lecture and it allows them to apply these concepts through realistic simulated patient interactions. The training was conducted virtually, and eight students participated. The impact of the training was evaluated based on changes in both confidence and competence of the participants' patient communication skills. Participants were asked to fill out a survey to assess their confidence on communicating with patients before and after the training. They also underwent a simulated patient interaction pre- and postlecture. Their performance during these was evaluated by both the simulated patient actors and the participants themselves using a rubric. Each data set was paired and analyzed for significance using a Wilcoxon rank-sum test with an alpha of 0.05. Participants reported significantly higher confidence in their feeling of preparedness to interact with patients (mean = 2.38 vs. 3.88, p = 0.008), comfort interacting independently (mean = 2.00 vs. 4.00, p = 0.002), comfort showing patients they are actively listening (mean = 3.50 vs. 4.50, p = 0.005), and confidence handling challenging patient interactions (mean = 1.88 vs. 3.38, p = 0.01), after the training. Their encounter scores, as evaluated by the simulated patient actors, significantly increased (mean = 77% vs. 91%, p = 0.022). Self-evaluation scores increased, but not significantly (mean = 62% vs. 68%, p = 0.184). The difference between the simulated patient and self-evaluation scores for the postinstruction encounter was statistically significant (p = 0.0014). This patient communication training for medical physics graduate students is effective at increasing both the confidence and the competence of the participants in the subject. We propose that similar trainings be incorporated into medical physics graduate training programs prior to students entering into residency.

Pixel Image Analysis and Its Application with an Alcohol-Based Liquid Scintillator for Particle Therapy.

We synthesized an alcohol-based liquid scintillator (AbLS), and we implemented an auxiliary monitoring system with short calibration intervals using AbLS for particle therapy. The commercial liquid scintillator used in previous studies did not allow the user to control the chemical ratio and its composition. In our study, the chemical ratio of AbLS was freely controlled by simultaneously mixing water and alcohol. To make an equivalent substance to the human body, 2-ethoxyethanol was used. There was no significant difference between AbLS and water in areal density. As an application of AbLS, the range was measured with AbLS using an electron beam in an image analysis that combined AbLS and a digital phone camera. Given a range-energy relationship for the electron expressed as areal density, the electron beam range (cm) in water can be easily estimated. To date, no literature report for the direct comparison of a pixel image analysis and Monte Carlo (MC) simulation has been published. Furthermore, optical tomography of the inverse problem was performed with AbLS and a mobile phone camera. Analyses of optical tomography images provide deeper insight into Radon transformation. In addition, the human phantom, which is difficult to compose with semiconductor diodes, was easily implemented as an image acquisition and analysis system.

COMP Report: An updated algorithm to estimate medical physics staffing levels for radiation oncology.

PURPOSE: Medical physics staffing models require periodic review due to the rapid evolution of technology and clinical techniques in radiation oncology. We present an update to a grid-based physics staffing algorithm for radiation oncology (originally published in 2012) that has been widely used in Canada over the last decade. MATERIALS AND METHODS: The physics staffing algorithm structure was modified to improve the clarity and consistency of input data. We collected information on clinical procedures, equipment inventory, and teaching activities from 15 radiation treatment centers in the province of Ontario from April 1, 2018, to March 31, 2019. Using these data sets, the algorithm's weighting parameters were adjusted to align the prediction of full-time equivalent (FTE) personnel with actual staffing levels in Ontario. The algorithm computes FTE estimates for medical physicists, physics assistants, engineering (electrical and mechanical), and information technology (IT) support. The performance of the algorithm was also tested in eight Canadian cancer centers outside of Ontario. RESULTS: The mean difference between the algorithm and actual staffing for the 23 Canadian cancer centers did not exceed 0.5 FTE for any staffing group. The results were slightly better in Ontario than in other provinces, as expected since the algorithm was optimized using Ontario data. There was a linear correlation between the algorithm predictions and the number of annual-treated cases for physicists, and physicists plus physics assistants. For other staff categories, the algorithm weighting parameters were not significantly altered, except for a reduction in mechanical engineering staff. Comparison with other published models suggests that the updated algorithm should be considered as a minimum recommended staffing level for the clinical support of radiation oncology programs. CONCLUSIONS: We support the use of grid-based physics staffing algorithms that account for clinical workload with flexibility to adapt to local conditions with variable academic and research demands.

The MedPhys match survey: Search criteria and advice for programs and applicants.

PURPOSE: The purpose of this study was to gauge the experiences of applicants and program directors (PDs) in the Medical Physics (MedPhys) Match (MPM) and to determine the most important characteristics and factors that influence decision-making for applicants and programs when screening, interviewing, and ranking in the MPM. Opinions were also solicited from applicants and PDs on the status of medical physics residencies and the selection process, such as the availability of residency positions and satisfaction with the match process. METHODS: A survey was sent to all applicants registered for the 2015-2018 MPM and to all PDs registered for the 2015-2017 MPM. Survey questions asked about the pre-interview screening, interview, and ranking stages of the residency match process. Survey data were analyzed using graphical methods and spreadsheet tools. RESULTS: An increasing percentage of applicants are female and/or hold a PhD as their highest degree. The over all number of interview invitations per applicant has increased, leading some applicants to decline interviews with the top reasons being cost of travel and scheduling conflicts. The top considerations for applicants in ranking programs were residency program/institution reputation, program structure/organization, and facilities/equipment available. The primary considerations identified by PDs for ranking applicants included impressions from the interview, personality fit, and clinical potential. While two-thirds of applicants agreed or strongly agreed with the statement that a residency position was difficult to obtain, roughly one-third of PDs agree that the current residency placement rate is a problem. CONCLUSION: Four years of survey data on the experiences of applicants and PDs participating in the MPM is useful to future participants navigating the residency match system. It is hoped that the data will be helpful to inform improvements and to enhance understanding of the residency match system and how it shapes our profession.

Model for implementation of a modern journal club in medical physics residency programs.

Journal clubs are a common educational experience for medical physics residents as a forum to discuss current research within the field. While journal clubs are valued by educational programs and accrediting bodies, there are a wide variety of ways in which these sessions are conducted. Unfortunately, there are currently few studies that have assessed the effectiveness of this educational method. This review defines journal club in the context of a medical physics residency and provides historical background for the meetings. Reasons why journal clubs are valued are presented, and several methods are described for conducting journal clubs. The format of journal clubs and scaffolding methods for guiding residents in gaining independence in critical reading skills are discussed. While the traditional journal club is a meeting, an alternative online virtual journal club is also described. Finally, a model of how a journal club can be applied in a medical physics residency is presented.

Evaluation of the rectal V30 parameter in patients diagnosed with postoperative endometrial cancer.

BACKGROUND: The present paper reports on analysis of 184 patients who were diagnosed with endometrial cancer. The main objective of this study was to address parameter Vrec(30Gy) which determines a volume of the rectum irradiated with a dose of 30 Gy during radiotherapy. MATERIALS AND METHODS: All patients were irradiated with an IMRT technique on linear accelerators. The planning target volume (PTV) contour was determined by a radiation oncologist. The clinical target volume (CTV) was drawn on CT images obtained in a prone position. For statistical analysis, appropriate tests (e.g. the Shapiro-Wilk, Wilcoxon) were used. RESULTS AND DISCUSSION: The performed analysis showed that the recommended condition for Vrec(30Gy) is met only in 3% of patients and the observed median value exceeds 90%. The obtained results were compared with the studies in which the Vrec(30Gy) values were related to various radiotherapy techniques. CONCLUSIONS: The analysis showed that the condition for Vrec(30Gy) is satisfied in the case of only 3% of patients. Due to the difficulty with meeting the condition, it should be reconsidered based on real results.
