Abstract
Operator radiation exposure is an important occupational hazard compounded over the course of an interventional radiologist's career. This study compared operator radiation dose to the eye and head for different positions around the patient. Compared with cases performed from the femoral region, exposures were 1.8 times higher at the side, and 1.6 times higher at the head, using conventional aprons, table shields, and mobile suspended shields. Exposures were 99% lower when using a suspended personal radiation protection system in all positions. In conclusion, standing at the side or head results in higher head exposures in a conventional setup.
摘要
操作人员的辐射暴露是一种重要的职业危害，在介入放射科医生的职业生涯中会不断累积。本研究比较了在患者周围不同位置时操作人员眼部和头部所接受的辐射剂量。与从股部区域进行的操作相比，使用传统围裙、手术台防护屏和移动悬吊防护屏时，在患者侧面操作的辐射暴露量高1.8倍，在患者头部操作的辐射暴露量高1.6倍。在所有位置使用悬吊式个人辐射防护系统时，辐射暴露量降低了99%。总之，在传统设置中站在患者侧面或头部会导致更高的头部辐射暴露。
