立体定向放射神经外科(简称SRS)原理就是利用立体定向的方法确定颅内靶点,然后引导多束放射线汇聚于颅内靶点,使局部获得犬剂量照射,导致靶点组织破坏而达到治疗的目的。1982年Colombo等首次将Varian 4MV直线加速器及其配套系统改制成SRS治疗装置并进行颅内肿瘤和血管性疾病的治疗,从而为SRS的普及奠定了基础。我们应用这一技术达一年之久,取得较好的疗效。根据我们的经验,在SRS治疗过程中颅内靶点的定位是极
Stereotactic Radiosurgery (SRS) principle is the use of stereotactic method to determine the intracranial target, and then guide the convergence of multiple beams of radiation in the intracranial target, the local dose of canine exposure, resulting in the destruction of target tissue to achieve the treatment purpose. In 1982, for the first time, Colombo et al transformed the Varian 4MV linear accelerator and its ancillary system into an SRS treatment device and carried out the treatment of intracranial tumors and vascular diseases, which laid the foundation for the popularization of SRS. We use this technology for a year, and achieved better results. In our experience, the positioning of intracranial targets during SRS is extreme
