  1. Radiosurgery

    Radiosurgery was originally defined by the Swedish neurosurgeon Lars Leksell as “a single high dose fraction of radiation, stereotactically directed to an intracranial region of interest”. The adverb stereotactic is made up from the Greek words: στερεος, which means solid, and τακτική which means "ability in disposition," interpreted as "arrangement, order" or "tactic" as used in military language. In radiosurgery, the word stereotactic hints at the three-dimensional coordinate system enabling co-identification of a virtual target on the patient's diagnostic images in the treatment planning computer with the actual target position in the patient anatomy. Although technological improvements in imaging and computing, increased availability and clinical adoption have broadened the scope of radiosurgery in recent years, the localization accuracy and precision implicit in the word “stereotactic” remains of utmost importance for radiosurgical interventions today. The original radiosurgery concept was recently stretched to include treatments up to five fractions and stereotactic radiosurgery as redefined as a distinct neurosurgical discipline that utilizes externally generated ionizing radiation to inactivate or eradicate defined targets in the head or spine without the need to make an incision.

U.S. National Library of Medicine

  1. Radiosurgery

    A radiological stereotactic technique developed for cutting or destroying tissue by high doses of radiation in place of surgical incisions. It was originally developed for neurosurgery on structures in the brain and its use gradually spread to radiation surgery on extracranial structures as well. The usual rigid needles or probes of stereotactic surgery are replaced with beams of ionizing radiation directed toward a target so as to achieve local tissue destruction.
