摘　　要：投照角度与剂量的关系对在介入诊疗过程中优化患者受照剂量十分重要。本试验的目的是分析不同投照角度下的曝光条件,摄影剂量和有效剂量,为优化投照角度,有效降低患者受照剂量提出建议。In interventional radiology, the location of X-ray field on patients＇ surface changed frequently according to observation purpose, Different projection angle causes different exposure to patients. In order to optimize projection angle and to minimize patient radiation risk, this paper analyzes the patient exposure using several parameters and effective dose under different projection angles during coronary angiography （CA） and percutaneous transluminal coronary angioplasty （PTCA） procedures,
