目的探讨心脏射频消融(RFA)术中DSA机不同采集帧数对术中患者左侧床旁配合护士不同站立位置辐射强度的大小及衰减情况,并绘制出辐射强度分层图,以便为介入护士的辐射防护提供指导,进而减少辐射.方法基于标准体模下,模拟心脏RFA,依次使用3种不同采集帧数,测量患者左侧床旁不同水平及垂直位置(共77个位置)辐射强度参数,共获取数据231组,并进行观察性分析、研究、绘图和总结.结果不同采集帧数在相同床旁位置产生的辐射强度差异有统计学意义(P0.05);在相同的采集帧数下,与射线发射球管不同水平位置产生的辐射强度差异有统计学意义(P

Objective To investigate the effect of different DSA collection frames on the radiation intensity and attenuation upon the coordination nurse standing at the left bedside at different positions during the performance of cardiac radiofrequency ablation (RFA) and to draw out a stratified map of radiation intensity in order to provide guidance for interventional nurses in radiation protection, thereby reducing radiation dose. Methods Simulation of cardiac RFA based on standard phantom was conducted. By using 3 different sampling frames in turn, th...
