摘　　要：探讨DSA术者受照剂量的影响因素,为优化辐射防护提供思路。介入手术施术者的受照剂量与手术难度、检查或治疗类别、手术熟练程度和工作量等诸多因素有关,透视时间与入射点空气比释动能和剂量面积乘积相关性较差。缩小照射野、降低脉冲频率、手动设定管电压均可有效降低施术者的受照剂量。穿戴个人防护用品虽能有效降低施术者受照剂量,但对眼晶体(特别是左眼)和手部的防护效果欠佳。因此,除进行针对性辐射安全培训外,还应常规监测这些部位的受照剂量。The exposure of DSA operators is related to suchfactors as the difficulty of surgery,the type of examination or treatment,the proficiency of the operation and the workload. Fluoroscopy time is poorly correlated to air kerma (AK),dose area product (DAP)and exposure dose. During DSA operations,narrowing radiation field,lowering impulse frequency,and manually setting tube voltage can effectively reduce the exposure to operators. While wearing personnel protective equipment can be beneficial,the lens (especial left eye) and hand protectionis not so good. So,the dose equivalents at theses sites should be routinely monitored,with targeted radiation safety training provided.
