数字减影血管造影术施术者受照剂量的影响因素

Abstract

Abstract: 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.

Key words: DSA, Operator, Exposure dose
