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.
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.
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%).
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.
讨论一种基于名为 virtX 的计算机培训和模拟系统，提高 C 臂操作和减少辐射危害的教育方法。
virtX 配备了散射辐射的可视化功能，并能够在放射模拟中包含患者定位变化。将 virtX 整合到 ORP 课程中，并基于问卷调查进行评估。
回复率为 73（n=77），平均年龄为 35.4（+/-9.2）岁，专业经验为 11.2（+/-10.4）年。91%的人经常使用 C 臂，8%的人偶尔使用，1%的人不使用。78%的人认为将患者模拟定位变化转换为模拟 X 射线图像的效果非常逼真，1%的人不同意（中立占 17%）。79%的人表示他们获得了有关避免不必要辐射暴露的新知识，10%的人没有（中立占 11%）。
virtX 模拟放射成像生成，包括患者定位和散射辐射的方法，在传授辐射防护和 C 臂操作知识方面被评估为具有适用性。
