Quantitative analysis of the factors which affect the interpatient organ‐at‐risk dose sparing variation in IMRT plans

Abstract

Quantitative analysis of patient anatomical features and their correlation with OAR dose sparing has identified a number of important factors that explain significant amount of interpatient DVH variations in OARs. These factors can be incorporated into evidence-based learning models as effective features to provide patient-specific OAR dose sparing goals.
