A computer program using Monte Carlo methods has been developed for the simulation of photon scattering in tissue-equivalent phantoms for incident x-rays in the diagnostic energy range. The study verified that the sampling schemes used in the program can produce random samples according to the theoretical probability distribution functions which describe the photon-scattering process. The Monte Carlo program was applied to determinations of the scatter fractions and edge responses for various phantom sizes, X-ray energies, and recording systems. These quantities were also measured experimentally under comparable imaging conditions. Excellent agreement was obtained between the predicted and experimental results. This investigation established the validity of our Monte Carlo calculations for studies of the physical characteristics of scattered radiation in diagnostic radiology.
已经开发了一种使用蒙特卡罗方法的计算机程序，用于模拟诊断能量范围内入射X射线在组织等效体模中的光子散射。该研究证实，程序中使用的采样方案可以根据描述光子散射过程的理论概率分布函数生成随机样本。蒙特卡罗程序被应用于确定各种体模尺寸、X射线能量和记录系统的散射分数和边缘响应。在可比的成像条件下，也对这些量进行了实验测量。预测结果与实验结果之间取得了极好的一致性。这项研究确立了我们的蒙特卡罗计算在诊断放射学中散射辐射物理特性研究方面的有效性。
