Dosimetric validation of an intrabeam gate model based on monte carlo geant4 toolkit, for IORT applications

Abstract

International audiencePurpose: Intraoperative RadioTherapy (IORT) with Intrabeam is delivered using a miniaturized radiation device with applicators generating the prescribed dose directed to the tumor bed. However, the dose delivered to the patient is not well known. In this context, a Monte Carlo (MC) calculation can accurately assess the dose delivered to the patient by simulating the particle transport. The aim of this study is to create and validate an Intrabeam model on the GATE platform, a MC code based on Geant4
