立体定向放射外科,即Gamma刀,是1951年由瑞典Lars Leksell教授首先创立的,它是一种采用立体定向技术确定头部靶点的坐标位置,然后用高能射线单次集中照射,使靶点组织破坏而达到治疗目的的脑外科技术。由于该技术具有无手术创伤、治疗精确、误差小(±0.1mm)、效果好、简便省时、治疗过程自动化、程序化等优点,Gamma刀已得到世界各国的承认和应用。截 Stereotactic radiosurgery, known as the Gamma Knife, was first established in 1951 by Professor Lars Leksell of Sweden. It was a stereotactic technique to determine the coordinates of the head of a target and then focus it on a single shot using a high-energy beam so that the target Tissue destruction and achieve the purpose of treatment of brain surgery technology. As the technology has no surgical trauma, accurate treatment, small error (± 0.1mm), good effect, simple and time-saving, automatic treatment process, program, etc., Gamma knife has been recognized and applied all over the world. cut
