Proton therapy as Radiotherapy a treatment modality to treat cancer due to the favorable ballistic properties of proton beams. The proton loses the majority of its energy in biological matter by interaction with the electrons of molecules by an inelastic coulomb process which is bigger and maximal in the end of the range causing ionization or excitation, also through the interaction with the nucleus which is a minimal process in biological matter. Otherwise the last process is the responsible of the lateral deviation of the protons from the center. Our work consists to calculate and evaluate the lateral scattering of the dose distribution of protons acceleration up to energies within the therapeutic window between 70 and 250 MeV using a voxelized water phantom as a 3D detector which detect and calculate the beam deposed energy and dose in any area of water phantom using Geant4 platform based on Monte-Carlo Method simulation. Results of our work are compared to the experimental references results and also to other methods of simulation results.
