开发了一个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[人体]体模中的光子散射。程序中使用的抽样方案根据描述光子散射过程的理论概率分布函数产生随机样本。蒙特卡罗程序被应用到各种模型尺寸，X射线能量和记录系统的散射分数和边缘响应的测定。这些量也在可比较的成像条件下进行了实验测量。预测结果与实验结果吻合良好。这些蒙特卡罗计算是有效的散射辐射的物理特性的研究在诊断放射学。
A computer program using Monte Carlo methods was developed for the simulation of photon scattering in tissue-equivalent [human] phantoms for incident X-rays in the diagnostic energy range. The sampling schemes used in the program produced 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. These Monte Carlo calculations are valid for studies of the physical characteristics of scattered radiation in diagnostic radiology.
