Abstract

Proton therapy is a precise form of radiation therapy and thus it requires accurate quality control of patients treatment. Protons may be more suitable than conventional X-rays for this task since the relative electron density distribution can be measured directly with proton computed tomography (pCT). However, proton CT has its own limitation. The main limit is that of spatial resolution limited by multiple coulomb scattering of proton inside the body of patient. In order to improve spatial resolution we need to determine the most likely path of single proton inside the body. In this work we realized a set of Monte Carlo simulations for the calculation of the most likely path
