Preliminary test of Bragg application for proton therapy using the Geant4 toolkit

In the treatment of tumors, the advantage of proton therapy is the sparing of dose to healthy tissue surrounding the target one, saving it from unnecessary damage. For protons, the dose increases with increasing penetration depth up to the Bragg peak that occurs near the end of the particle's range. This work shows the first results obtained with a specific application, Bragg, which has been developed with the use of the Geant4 package. This application aims to contribute to develop and test innovative treatment planning models for particle therapy. The results from the numerical simulation have been compared with the experimental data in the literature. The validation of models against experimental data is a prerequisite for the use of any application and, therefore, highly demanded.
