Simulation of Particle Interactions with Matter in Soft Tissue, Water, and Bone Using PHITS Monte Carlo Code: Physical Aspects of Bragg Curve for Carbon Ion Therapy

EasyChair Preprint no. 9641

Abstract

Monte Carlo simulations are becoming widely regarded as the most accurate tool for calculating the interactions of particles with matter. In this study, we first investigated the influence of the average excitation energy of water (I_W) on the Bragg Peak (BP) location. Second, we used the PHITS code to investigate the Bragg curve of ¹²C ion beams at energy of 200 MeV/u in three mediums: water, soft tissue, and bone. Third, we examine how secondary particles affect the overall dose. The results indicate that the position of the BP is strongly affected by the average excitation energy of water. The tail dose beyond the BP is generated mainly by secondary fragments of the primary carbon ion beams. In addition, PHITS has been shown to faithfully reproduce the measured Bragg curves
