Abstract

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, 4He, 7Li, 8Be, 10B and 12C 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)

用蒙特卡罗模拟系统研究重离子横向散射分布

放射治疗是目前应用最广泛的肿瘤治疗方法之一。由于与光子治疗相比，重离子具有优越的物理和放射生物学特性，其治疗应用受到了广泛的关注。借助这些特性，重离子放疗减少了对邻近正常组织的损伤，而对肿瘤的损伤却增加了。本研究的目的是分析在治疗能量范围内选定的P、4He、7Li、8Be、10B和12C重离子在水影中的横向散射分布。采用蒙特卡罗(MC)方法模拟离子在物质中的输运(TRIM)。本研究将为文献提供的主要创新是计算靠近临界点的肿瘤治疗中的一个重要参数，如侧向散射。因此，正确选择重离子可以最大限度地降低继发性癌症的风险。在这种情况下，其目的是确定最理想的离子。(抽象)
