Dosimetric effect of respiratory motion on volumetric‐modulated arc therapy‐based lung SBRT treatment delivered by TrueBeam machine with flattening filter‐free beam

Abstract

The purpose of this study is to investigate the interplay effect between dynamic MLC movement and tumor respiratory motion in volumetric-modulated arc therapy (VMAT)-based lung SBRT treatment delivered by the flattening filter-free (FFF) beam of a Varian TrueBeam machine. Six lung cancer patients with tumor motions ranging between 0.5-1.6 cm were recruited… (More)
