The Cyberknife is an image-guided robotic radiosurgery system. The image guidance system includes a kilovoltage X-ray imaging source and amorphous silica detectors. The radiation delivery device is a mobile X-band linear accelerator mounted onto a robotic arm. Through a highly complex interplay between the image guidance system, an automated couch, and the high-speed linear accelerator, near real-time tracking of the target is achieved. The Cyberknife gained Federal Drug Administration clearance in the United States in 2001 for treatment of tumors "anywhere in the body where radiation treatment is indicated." Because the Cyberknife system does not rely on rigid fixation of a stereotactic frame, tumors outside of the intracranial compartment, even those tumors that move with respiration can be treated with a similar degree of ease as intracranial targets. A description of the Cyberknife technology and a review of some of the current intracranial and extracranial applications are detailed herein.
射波刀是一种影像引导的机器人放射外科手术系统。影像引导系统包括一个千伏级X射线成像源和非晶硅探测器。放射治疗设备是安装在机器人手臂上的可移动X波段直线加速器。通过影像引导系统、自动治疗床和高速直线加速器之间高度复杂的相互作用，实现了对目标的近实时追踪。射波刀于2001年在美国获得美国食品药品监督管理局的批准，用于治疗“身体任何需要进行放射治疗的部位”的肿瘤。由于射波刀系统不依赖于立体定向框架的刚性固定，颅内腔室以外的肿瘤，甚至那些随呼吸移动的肿瘤，都可以像颅内靶点一样轻松治疗。本文详细介绍了射波刀技术，并对目前一些颅内和颅外应用进行了综述。
