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，快速并精确地计算出剂量分布
In this paper, a rapid X-knife computational dose algorithm is proposed. According to the high-energy X-ray characteristics and the narrow beam radiation dose distribution mathematical model used in stereotactic radiosurgery, the dose distribution can be calculated quickly and accurately by changing the searching step.
