摘要

为探讨质子在人体组织（或组织等效介质）中能量沉积的微观特性

在对人体组织材料进行分析的基础上

确定了水蒸汽作为组织等效材料的合理性

利用蒙特卡罗方法模拟了质子在介质中的微观行为。通过对计算所得数据进行系统分析

得出质子在组织等效材料中能量沉积微观特性的一些规律与特点。质子在介质中主要把其能量交给电子

最后由电子完成其能量沉积过程

所有这些小能量沉积事件构成了质子在介质中的几何径迹。

Abstract

To research the micro-specialty of proton energy deposition in body-tissue or tissue equivalent material

water vapor was considered to be reasonable as the tissue equivalent material on the basis of analysis of the body-tissue

and Monte Carlo method was used to simulate the behavior of proton in the tissue equivalent material. Some features about the micro-specialty of proton energy deposition in tissue equivalent material were given through the analysis of data from the calculation. Proton will give energy to the electrons along its track in tissue equivalent material

and energy of these electrons will give out in the end. All these energy deposition events made up the proton track in tissue material.
