Sci-Fri PM: Delivery - 01: Approach to evaluate the accuracy of individual control-points of a VMAT delivery measured by an EPID.

Abstract

A unique approach that uses Monte Carlo (MC) methods to validate time-resolved measured dose by an electronic portal imaging device (EPID) during delivery of volumetric modulated arc therapy (VMAT) treatments was investigated. Time-resolved dose is simultaneously scored in both the patient and EPID geometries. A RapidArc© verification plan was generated and… (More)
