延长源探距测量立体定向照射野参数

The method of extension SPD to measure clinic parameters of stereotactic radio field

本文采用延长源探距的方法测量立体定向放射手术或放射治疗的临床应用参数。将其测量结果与国内外有关测量结果相比较，误差较小，可以用于放射手术和放射治疗。

This paper describes a method of extension SPD to measure clinic parameters of stereotactic radio feilds. In comparable range, it show available for measuring clinic parameters of stereotactic radio field to make a comparision between our results and Zhang hongzi et al.
