“…Th ere is a large body of research that is yet to be applied to simulated learning. Eleven studies were identifi ed that reported on simulation techniques specifi c to DR (n = 7) [13][14][15][16][17][18][19] and RT (n = 4). [20][21][22][23] One study, assessing the learning eff ectiveness of a live simulated scenario 14 of a critical incident within the computed tomography suite demonstrated improved student performance when they were given the opportunity to view and critique a staged simulated scenario before becoming immersed in that scenario themselves.…”

Purpose: To investigate whether simulated learning programs can be expanded to include aspects of clinical education in medical radiation science (MRS) curricula. Methods: Information about the use and perceptions of simulation in MRS education was collected from academic, clinical and accrediting stakeholders using semi-structured telephone interviews, an online survey, invited comment and face to face consultative meetings. Participants represented the MRS sub-disciplines: Diagnostic Radiography, Radiation Th erapy, Nuclear Medicine and Medical Sonography. Th e following themes were explored with regard to simulation programs: existing, potential expansion of, eff ectiveness of and implementation. Results: Currently, simulation is widely implemented across Australia to deliver MRS curricula. Areas for potential expansion include: authentic replication of the clinical environment with facilities for video recording, fl exible multipurpose space, video demonstrations, online computer assisted tutorials, interactive programs, authentic scenarios using role play or live actors, virtual reality environments and comprehensive digital imaging libraries. Th e literature revealed no fi rm evidence that simulation training was more eff ective than clinical training. Participants in our project viewed simulation as complementary to clinical placement, but not as a replacement for the complexity of situations that clinical placement presents.Stakeholders cautioned for careful curriculum planning and evaluation when implementing simulation in MRS education. Conclusion: Th is consultative process provided a comprehensive summary of the current use of simulation in MRS and the potential for expansion with examples from the sub-disciplines. Th ere is a need for further research to investigate the eff ectiveness of simulation in clinical skills development.

“…Optimizing the position of any C-arm device (to minimize radiation exposure) is challenging since the context, the imaging parameters, and the patient's and staff's positioning need to be considered in the MC simulations. As in Bott et al (22), the real C-arm imaging parameters (tube kilovoltage, filtration, aperture angle and beam projection), together with the X-ray photon scattering process, are all considered by the simulation. These can be extracted from the C-arm device application programming interface (API).…”

Le laboratoire d'éducation médicale, de formation et d'intervention assistée par ordinateur (METRICS) vise à intégrer de nouvelles technologies à réalité mixte à des interventions assistées par ordinateur. Nous présentons deux technologies ayant des objectifs spécifiques pour optimiser le flux de travail chirurgical et minimiser l'exposition aux rayonnements dans les chirurgies orthopédiques, traumatologiques et vasculaires. La première est un fluoroscope C-arm à réalité augmentée, qui fournit une visualisation intuitive en temps réel en superposant avec précision les rayons X aux images vidéo. La seconde est une interface utilisateur «Desired-views» qui résout les problèmes liés au contrôle optimal des fluoroscopes C-arm pour leur repositionnement constant pendant la chirurgie, soit par l'interventionniste, soit par l'équipe chirurgicale.

“…To improve training in C-arm operation, the virtX (virtual x-ray) computer-based training system was developed by an interdisciplinary team of medical informatics specialists, trauma surgeons, and radiologists (13)(14)(15)(16)). The virtX system was designed to fill the gap between the teaching of theoretical principles of C-arm operation and the actual use of a C-arm with two additional stages of interactive training: (a) training in the so-called virtual mode (training mode 1), consisting of a series of computer-based imaging exercises in which C-arm use in various surgical procedures is simulated by the trainee on a desktop personal computer (PC) with a keyboard, mouse, and monitor; and (b) training in a simulated operating room environment, in the so-called real mode (training mode 2), which involves manipulation of an actual C-arm (without any actual imaging or radiation), operating table, and mannequin while the computer-based simulation system provides cues and performance feedback (Fig 1).…”

Mobile image intensifier systems (C-arms) are used frequently in orthopedic and reconstructive surgery, especially in trauma and emergency settings, but image quality and radiation exposure levels may vary widely, depending on the extent of the C-arm operator's knowledge and experience. Current training programs consist mainly of theoretical instruction in C-arm operation, the physical foundations of radiography, and radiation avoidance, and are largely lacking in hands-on application. A computer-based simulation program such as that tested by the authors may be one way to improve the effectiveness of C-arm training. In computer simulations of various scenarios commonly encountered in the operating room, trainees using the virtX program interact with three-dimensional models to test their knowledge base and improve their skill levels. Radiographs showing the simulated patient anatomy and surgical implants are "reconstructed" from data computed on the basis of the trainee's positioning of models of a C-arm, patient, and table, and are displayed in real time on the desktop monitor. Trainee performance is signaled in real time by color graphics in several control panels and, on completion of the exercise, is compared in detail with the performance of an expert operator. Testing of this computer-based training program in continuing medical education courses for operating room personnel showed an improvement in the overall understanding of underlying principles of intraoperative radiography performed with a C-arm, with resultant higher image quality, lower overall radiation exposure, and greater time efficiency.
