The interventional cardiology was recently implemented at the University Hospital of Osijek. Patients' absorbed doses during coronary angiography (CA) and the percutaneous transluminal coronary angioplasty (PTCA) procedures were measured and compared with published data and international standards. All patients undergoing CA or PTCA procedures during a 1-month period were included in the study. Patients' doses are expressed in terms of dose area product (DAP) per procedure. The patients' DAPs ranged from 2.6 to 210 Gy cm2 (average of 59 Gy cm2) during CAs, and from 61 to 220 Gy cm2 (average of 120 Gy cm2) during PTCAs. Patients' doses during CAs and PTCAs at the University Hospital of Osijek are in good agreement with the published ones. In complex cases, the radiochromic dosimetry films were used to show possible dose distributions across patient's skin. The film dosimetry showed a limitation of using only DAP values for the estimation of skin injuries risk.
奥西耶克大学医院最近开展了介入心脏病学项目。对冠状动脉造影（CA）和经皮冠状动脉腔内血管成形术（PTCA）过程中患者的吸收剂量进行了测量，并与已发表的数据和国际标准进行了比较。在1个月期间内接受CA或PTCA手术的所有患者均纳入研究。患者的剂量以每次手术的剂量面积乘积（DAP）表示。在CA期间，患者的DAP范围为2.6至210 Gy cm²（平均59 Gy cm²），在PTCA期间为61至220 Gy cm²（平均120 Gy cm²）。奥西耶克大学医院CA和PTCA期间患者的剂量与已发表的剂量非常一致。在复杂病例中，使用放射变色剂量测定薄膜来显示患者皮肤可能的剂量分布。薄膜剂量测定显示仅使用DAP值来估计皮肤损伤风险存在局限性。
