Patient skin doses were measured using Kodak EDR2 film for 20 coronary angiography (CA) and 32 percutaneous transluminal coronary angioplasty (PTCA) procedures. For CA, all skin doses were well below 1 Gy. However, 23% of PTCA patients received skin doses of 1 Gy or more. Dose-area product (DAP) was also recorded and was found to be an inadequate indicator of maximum skin dose. Practical compliance with ICRP recommendations requires a robust method for skin dosimetry that is more accurate than DAP and is applicable over a wider dose range than EDR2 film.
使用柯达EDR2胶片测量了20例冠状动脉造影（CA）和32例经皮腔内冠状动脉成形术（PTCA）患者的皮肤剂量。对于CA，所有皮肤剂量均远低于1 Gy。然而，23%的PTCA患者接受的皮肤剂量达到或超过1 Gy。还记录了剂量面积乘积（DAP），发现它作为最大皮肤剂量的指标并不充分。要切实遵守国际辐射防护委员会（ICRP）的建议，需要一种比DAP更准确、且比EDR2胶片适用剂量范围更广的强大皮肤剂量测定方法。
