Proton therapy is a high-quality radiation therapy that uses a proton beam to irradiate cancer tissue. The advantage of this type of treatment is a highly conformal dose deposition due to the presence of the Bragg peak. The results of the Geant4 simulation (version 10.6.3.) are presented. The dose distribution was studied in the phantom materials with proton beams of different geometry and intensity. Different geometric shapes are used for phantoms, which are filled with water and carbon. 3D phantom models are divided into voxels of different sizes. Obtained simulated data was used for calculations of dose-volume histograms for different proton beam parameters and different phantom models.
