Monte Carlo simulations as well as analytical computations of proton transport in material media require accurate values of multiple Coulomb scattering (MCS) angles. High-quality experimental data on MCS angles in the energy range for proton therapy are, however, sparse. In this work, MCS modeling in proton transport was evaluated employing an experimental method to measure these angles on a medical proton beamline in clinically relevant materials. Results are compared to Monte Carlo simulations and analytical models.

质子多次库仑散射的实验和蒙特卡罗模拟

蒙特卡罗模拟以及材料介质中质子传输的分析计算需要多个库仑散射 (MCS) 角的准确值。然而，关于质子治疗能量范围内 MCS 角的高质量实验数据很少。在这项工作中，使用实验方法来评估质子传输中的 MCS 建模，以测量临床相关材料中医用质子束线上的这些角度。结果与蒙特卡罗模拟和分析模型进行了比较。
