Investigation of Lateral Scattering Profiles of Heavy Ions with Monte Carlo Simulation System

Radiation therapy is one of the most widely used treatments for tumor treatment. The therapeutic use of heavy ions has received much attention due to the advantageous physical and radiobiological properties compared to photon-based therapy. With the help of these properties, heavy ion radiotherapy reduces the damage to the adjacent normal tissues, while the damage to tumors is increased. The aim of this study is to analyze the lateral scattering profiles of selected P,
⁴
He,
⁷
Li,
⁸
Be,
¹⁰
B and
¹²
C heavy ions in the water phantom in the therapeutic energy range. This analysis was performed using Monte Carlo (MC) based TRansport of Ions in Matter (TRIM) simulation. The main innovation that this study will provide to the literature is the calculation of an important parameter in the treatment of tumors close to critical points, such as lateral scattering. Thus, it is the correct selection of heavy ions that will minimize the risk of secondary cancer. In this context, it is aimed to determine the most ideal ion. (Abstract)
