Extending the Monte Carlo calculations of the scatter dose distribution of needle ray beams performed earlier, the dose distribution was determined as a function of spectral scatter photon fluence. From the disappearance of dose contributions to certain group fluences there has to be concluded that definite parts of spectral photon fluence also must vanish. The results show the existence of interfaces which are effective for scatter photons with distinct levels of energy. Dependence of the interfaces on the limitation of the absorbing space and on the energy of primary photons is being investigated.
扩展早期进行的针状射线束散射剂量分布的蒙特卡罗计算,剂量分布被确定为光谱散射光子注量的函数。从对某些组注量的剂量贡献消失可以得出结论,光谱光子注量的某些特定部分也必然消失。结果表明存在对具有不同能量水平的散射光子有效的界面。正在研究这些界面与吸收空间限制以及初级光子能量的相关性。
