本文给出一种自动、快速计算等中心放射治疗中平均照射深度的方法。它是基于严格的数学推导并加上合理的近似而得到的。文中还给出了具体实现的算法和结果。为了公式推导和计算的方便,文中做了射束床角、射束机架角的定义。
This paper presents a method of automatic and rapid calculation of the average depth of radiation in central radiation therapy. It is based on rigorous mathematical derivation and a reasonable approximation. The article also gives the concrete realization of the algorithm and results. For the convenience of formula derivation and calculation, the definition of beam bed angle and beam gantry angle was done in this paper.
