Radiosurgery history

摘要

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, metas-tases, 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~R. It is now challenged by some linear accelerators providing radiosurgery technology, such as the CyberKnife~R, the Novalis Tx~R radiosurgery platform, and the True Beam~R linear accelerator.
