During the intraoperative radiograph generation process with mobile image intensifier systems (C-arm) most of the radiation exposure for patient, surgeon and operation room personal is caused by scattered radiation. The intensity and propagation of scattered radiation depend on different parameters, e.g. the intensity of the primary radiation, and the positioning of the mobile image intensifier. Exposure through scattered radiation can be minimized when all these parameters are adjusted correctly. Because radiation is potentially dangerous and could not be perceived by any human sense the current education on correct adjustment of a C-arm is designed very theoretical. This paper presents an approach of scattered radiation calculation and visualization embedded in a computer based training system for mobile image intensifier systems called virtX. With the help of this extension the virtX training system should enrich the current radiation protection training with visual and practical training aspects.
在使用移动影像增强系统(C形臂)进行术中X光片生成过程中,患者、外科医生和手术室人员所受到的大部分辐射暴露是由散射辐射造成的。散射辐射的强度和传播取决于不同参数,例如一次辐射的强度以及移动影像增强器的位置。当所有这些参数都得到正确调整时,通过散射辐射造成的暴露可降至最低。由于辐射具有潜在危险性且无法被人类的任何感官所感知,目前关于C形臂正确调整的培训设计得非常理论化。本文介绍了一种散射辐射计算与可视化方法,该方法嵌入到一个名为virtX的基于计算机的移动影像增强系统培训系统中。借助这一扩展功能,virtX培训系统应能在视觉和实践培训方面丰富当前的辐射防护培训。
