立体定向放射神经外科采用等中心直线加速器治疗疾病,是以立体定向系统为基础,借助先进的神经影像(CT、磁共振、数字减影、血管造影)进行中枢神经系统疾病精确定位,利用大剂量高能物理射线局限性的一次或几次照射颅内靶点或病灶,造成局部组织坏死而达到治疗目的。由于此法无需开颅,从而避免了常规开颅手术发生的麻醉意外,大出血,重要功能结构 Stereotactic radiosurgery uses the isocenter linear accelerator to treat diseases. Based on the stereotactic system, precise positioning of central nervous system diseases with advanced neuroimaging (CT, magnetic resonance imaging, digital subtraction, angiography) High-energy physical ray limitations once or several intracranial irradiation target or lesion, resulting in local tissue necrosis and achieve therapeutic purposes. Because this method without craniotomy, thus avoiding the occurrence of conventional craniotomy accidental anesthesia, bleeding, an important functional structure
