Comparison of rectal dose-volume constraints of IMRT prostate treatment planning

Abstract

An optimal set of dose-based rectal constraints (maximum rectal dose 74.1 Gy, maximum help volume dose 50 Gy) has been developed for Varian planning software. hese parameters will constitute a starting point for the prostate IMRT plan optimization.
