目的:分析和比较宫颈癌术后调强放射治疗(IMRT)中笔形束卷积算法(PBC)和各向异性分析算法(AAA)的剂量学差异。方法:随机选取30例宫颈癌术后患者,分别在Eclipse治疗计划系统上采用PBC算法和AAA算法设计IMRT计划,并生成相应的验证计划,比较靶区及危及器官的剂量学参数。结果:两种算法计算所得靶区的D_(5%)、D_(50%)、D_(95%)、D_(98%)、 D_(mean)均有显著统计学差异(P

Objective To analyze and compare dosimetric differences between pencil beam convolution (PBC) algorithm and anisotropic analytical algorithm (AAA) in designing intensity-modulated radiotherapy plans for postoperative patients with cervical cancer. Methods Based on Eclipse treatment planning system, PBC algorithm and AAA were separately used to design intensity-modulated radiotherapy plans for 30 postoperative patients with cervical cancer, and the corresponding verification plans were also generated. The dosimetric parameters of target areas and organs-at-risk were compared. Results Statistica...
