摘要:
 【摘要】 目的 测量和评价在冠状动脉介入治疗中第1术者在重要辐射剂量区域内所受辐射剂量,为操作者的辐射防护提供指导和帮助。方法 选用冠心病介入治疗中常用的7个体位,在无辐射防护情况下分别测定不同高度、不同视野、不同采集频率时第1术者体表入射剂量率,并绘制体表入射剂量分布图。结果 区域内剂量峰值都出现在20 ~ 70 cm高度范围内,在130 ~ 160 cm高度范围内又出现剂量次高峰,投照体位中以左脚位(spider位)时体表入射剂量最大;高采集频率时的剂量率明显高于低采集频率时;大视野剂量率明显高于小视野。结论 冠状动脉介入治疗过程中,重点关注20 ~ 70 cm高度区域的放射防护,而对于左脚位以及130 ~ 160 cm高度范围内的辐射剂量的防护也不容忽视。在不影响图像质量和操作的情况下,应当选取采集频率低和小视野的曝光参数,尽可能减少术者的吸收剂量。
