本中心自１９９３年１２月至１９９７年８月期间，利用伽玛刀治疗帕金森氏病９０例。总结了一套伽玛刀治疗功能性疾病的ＭＲ定位方法，包括头架的固定，靶点的选择及其坐标的计算修正公式和由公式推导的修正表。分析了头架固定对靶点坐标确定的影响因素，比较了修正前后的坐标差值，为伽玛刀治疗功能性疾病的定位提出一种新的思想。
The center from December 1993 to August 1997 period, the use of gamma knife treatment of Parkinson’s disease in 90 cases. Summarizes a set of Gamma Knife MR positioning method for the treatment of functional diseases, including the fixation of the head frame, the selection of the target and the calculation and correction of its coordinates and correction tables derived from the formula. The influencing factors for the determination of the coordinates of the target were analyzed. The difference of coordinates before and after correction was compared to provide a new idea for positioning the gamma knife in the treatment of functional diseases.
