Comparison of dosimetric characteristics between flattening filter‐free and flattening filter mode volumetric‐modulated arc therapy plans in rectal cancer

Abstract

We aimed to compare the dosimetric characteristics of 6‐MV flattening filter mode (FF) and flattening filter‐free mode (FFF) volumetric‐modulated arc therapy (VMAT) plans in preoperative radiotherapy for rectal cancer using an Edge linear accelerator.
