Within the last decades, radiosurgery, also known as stereotactic radiotherapy, has become more and more popular as a non-invasive treatment of small benign tumours, arteriovenous malformations, metastases, and also some functional neurological structures, such as the fifth cranial nerve for trigeminal neuralgesia. It allows precisely delivering very high dose in a small volume under stereotactic conditions with minimal irradiation of tissue around the area. The first equipment devoted to radiosurgery was the Leksell Gamma Knife®. It is now challenged by some linear accelerators providing radiosurgery technology, such as the CyberKnife®, the Novalis Tx® radiosurgery platform, and the True Beam® linear accelerator.
在过去几十年里，放射外科手术，也被称为立体定向放射治疗，作为一种治疗小型良性肿瘤、动静脉畸形、转移瘤以及一些功能性神经结构（如用于治疗三叉神经痛的第五对脑神经）的非侵入性治疗方法，越来越受欢迎。它能够在立体定向条件下，精确地在小体积区域内给予非常高的剂量，同时使该区域周围的组织受到最小程度的照射。第一台专门用于放射外科手术的设备是Leksell伽玛刀®。如今，它受到了一些提供放射外科手术技术的直线加速器的挑战，比如射波刀®、Novalis Tx®放射外科手术平台以及True Beam®直线加速器。
