目的初步探讨固定剂量率容积调强在直肠癌术后盆腔放射治疗中的可行性。方法选取10例直肠癌放疗患者,利用Ray Station计划系统为每例患者制定可变剂量率容积调强（VDR-VMAT）、固定剂量率容积调强（CDR-VMAT）和5野静态调强（5F-s IMRT）计划。运用剂量体积直方图评估三种计划的靶区、危及器官和正常组织剂量学参数,评估机器总跳数（MU）和计划执行时间。结果靶区剂量方面,三种计划的靶区D2%、Dmean、D98%、HI和CI在总体上均有差异（P

Objective The objective of this study was to investigate the feasibility of fixed dose rate volumetric modulation in pelvic radiotherapy after rectal cancer surgery. Methods Ten patients with rectal cancer radiotherapy were enrolled in this study. The Ray Station planning system was used to establish a variable dose rate volumetric modulation（ VDR-VMAT）,a fixed dose rate volume modulation（ CDR-VMAT）,and a 5-field static intensity modulated radiation therapy（ 5 F-s IMRT） plans for each patient. Dose volume histograms were used to evaluate ...
