Simulation of proton beam interaction with ovary and prostate tissues using SRIM software
Proton beam therapy is based on transport of proton particles that are used to irradiate and deposit energy on tumor or cancer cells. With appropriately chosen beam parameters, proton irradiation results in the effective destruction of invasive cancer cells. In this paper, the Stopping and Range of Ions in Matter (SRIM) simulation software is used to calculate the energy loss and ion trajectories of protons interacting with ovary and prostate tissues. Using SRIM’s Stopping / Range Tables and TRIM modules, it was found out that most of the energy loss of protons in both tissues was from the ionization interaction. Moreover, the energy loss due to phonons was found to be insignificant as it only accounts for less than 1% energy loss in both tissues.
