摘　　要：射波刀是近年来新出现的一种无框架立体定向放射治疗设备,它利用智能化的机器人操控直线加速器,以亚毫米级的精度治疗体内任何部位的肿瘤。它采用实时图像引导系统以及呼吸追踪系统,以2～5次剂量分割给予病灶多波束照射,同时把对病灶周围健康组织的损伤减少到最小程度,因而在治疗颅内肿瘤方面取得了良好的疗效。Cyberknife is a new flameless stereotactic radiation device, which utilizes intelligent robotics carrying a compact X-band linear accelerator to treat tumors anywhere in the body with sub-millimeter accu- racy. It uses real-time image guidance and respil＇atory tracking technology, giving staged （typically 2-5 ）ses- sions by delivering multiple beams of precisely directed radiation that converge upon the lesion while minimi- zing injury to the surrounding healthy tissue, which has seen good effect in the treatment of intracranial
