Improving education on C-arm operation and radiation protection with a computer-based training and simulation system

Purpose To discuss an approach to improve education in C-arm operation and reduction of radiation hazards based on a computer based training and simulation system called virtX. Methods virtX is equipped with a visualization of scattered radiation and means to include patient positioning changes in radiograph simulation. virtX was integrated in a course for ORP and evaluated based on questionnaires. Results Response rate was 73% (n = 77), mean age 35.4 (+/- 9.2) and professional experience 11.2 +/- 10.4 years. 91% use a C-arm regularly, 8% casually and 1% not. 78% agree that the translation of patient dummy positioning changes to simulated X-ray images is sufficiently realistic, 1% disagree (neutral 17%). 79% state that they acquired new knowledge concerning avoiding unnecessary radiation exposure, 10% do not (neutral 11%). Conclusions The virtX-approach of simulating radiograph generation including patient positioning and scattered radiation was evaluated positively concerning its suitability for imparting knowledge regarding radiation protection and C-arm operation.
