伽玛刀是世界上最昂贵的医疗设备之一，我国从１９９２年开始引进。１９９５年卫生部等联合发文暂缓装备。为了规范提供方和患方的行为，以及为卫生行政部门提供决策依据，我们开展了伽玛刀的技术评估。在评估前拟定评估步骤，然后确定评估内容与方法。评估结果，国外１９９４年有５６台伽玛刀，平均每台治疗１９０例，治疗病种是：动静脉畸型病人占３２％，肿瘤病人占６５％，功能性疾病占２％。我国１３台伽玛刀到１９９５年底共治病人７０００例，前６位病种是转移瘤等，虽然比例和顺位与世界有差异，但病例分析结果完全一致。
Gamma Knife is one of the most expensive medical equipment in the world. Our country started to introduce it in 1992. In 1995, the Ministry of Health and other joint issued a postponement of equipment. In order to regulate the behavior of providers and patients, and to provide decision-making basis for the health administration, we conducted a technical assessment of gamma knife. Develop evaluation steps prior to evaluation and then determine the content and method of evaluation. As a result of the assessment, there were 56 Gamma Knives in 1994 abroad, with an average of 190 cases per treatment. The treatment types were: 32% of patients with arteriovenous malformations, 65% of cancer patients and 2% of functional diseases. By the end of 1995, 13 Gamma Knives in our country had co-treated 7000 patients. The first 6 diseases were metastatic tumors. Although the proportions and rankings were different from those in the world, the results of case analysis were completely consistent.
