Simulation by Geant4 of hadrontherapy beam line

Abstract

Hadrontherapy represents a pioneer technique, and only few centers worldwide can provide this advanced and specialized cancer treatment. Geant4 (GEometry ANd Tracking 4) is a C++, free and open toolkit that used to simulate the interaction of particles in matter. It is employed in various fields from highenergy physics, nuclear physics to medicine. By means of Monte Carlo simulation tool Geant4, we have simulated the hadrontherapy beam line typical of a proton-therapy line modeled in the category of the advanced examples with all its elements: the diffusers, range shifters, collimators and detectors. This Simulation has permited the calculation of dose and Linear Energy Transfer (LET). In this context, this study reports the first results of our simulation realized by means of Geant4 10.2 version and their comparizon with those obteined by Cironne.
