To evaluate the influence of different sources and treatment planning systems (TPSs), we calculated the dose distributions of 10 patients treated by HDR intracavitary brachytherapy. The dose distributions of treatment plans were compared to the points A, B and ICRU bladder and rectum reference points located in the relevant clinical planes. The results show that the dose discrepancies between the two treatment plans are mainly affected by the differences in the physical characteristics of source and the positioning method in TPSs.
为评估不同源和治疗计划系统（TPS）的影响，我们计算了10例接受高剂量率腔内近距离放射治疗患者的剂量分布。将治疗计划的剂量分布与位于相关临床平面的A点、B点以及国际辐射单位与测量委员会（ICRU）膀胱和直肠参考点进行比较。结果表明，两种治疗计划之间的剂量差异主要受源的物理特性和TPS中定位方法差异的影响。
