赛博刀是一种新型立体定向放射治疗机,采用影像引导实时跟踪系统,指导机械臂带动直线加速器追踪靶区进行治疗。它重复性好,精确度高,创伤小且适应面广,可进行正/逆向治疗计划,也可分次治疗,且兼容放射外科和放射治疗两种功能。已被美国食品与药物管理局批准应用于全身多种疾病的治疗。多项研究结果证明了赛博刀治疗的可行性和安全有效性。 Saber knife is a new type of stereotactic radiotherapy machine, using image-guided real-time tracking system to guide the robot to drive the linear accelerator to track the target area for treatment. It has good repeatability, high accuracy, small trauma and wide adaptability. It can be planned for positive / negative treatment, and also can be divided into treatment, which is compatible with two functions of radiosurgery and radiotherapy. It has been approved by the U.S. Food and Drug Administration for the treatment of multiple systemic diseases. Several studies have proved the feasibility and safety and efficacy of cyber knife treatment.
