摘要
本文提出了一种X刀快速计算剂量算法,根据立体定向放射外科中使用的高能X射线特性和窄束射线剂量分布数学模型,通过改变步长的搜索。
In this paper,a method for the rapid dose calculation in the treatment planning for X knife is presented.According to the character of the high enegy X ray beams used is steretactic radio surgery and the mathmatical model of narrow beam dose distribution,through search with variable grid spacings,the dose distribution can be calculated rapidly and accurately.
