摘　　要：传统的立体定向放射外科设备要用螺钉将金属定位框架固定在患者颅骨,利用三维集束单次大剂量照射颅内病变,以达到不开颅的手术效果。美国Accuray公司研制的射波刀系统,作为新一代的立体定向放射外科设备,具有实时影像引导及同步动态追踪的优势,无需有创的定位框架,将立体定向放射外科技术的应用,从头颈部肿瘤延伸至脊椎以及全身其他部位的肿瘤。文中对射波刀系统的配置、技术特点、治疗流程以及射波刀在颅内外良恶性肿瘤的临床应用作一系统的综述。Stereotactic radiosurgery is a non-invasive technique that utilizes precisely targeted radiation as an alternative surgical tool. Conventional radiosurgery devices, such as Gamma Knife and X-Knife, rely upon skeletally attached stereotactic frames to immobilize the patient and accurately localize intracranial neoplasm. The CyberKnife （Accuray, Inc., Sunnyvale, California）, a new and revolutionary stereotactic radiosurgery instrument, makes it possible to administer radiosurgery without a frame. The superiorities of the CyberKnife, including real-time image-guided irradiation and dynamic synchronous tracking, extend stereotactic radiosurgery for a range of extracranial tumors and some non-neoplastic disorders. This paper reviews CyberKnife technology and its clinical application in intracranial neoplasm and extracranial tumors.
