'''Radiosurgery''' is [[surgery]] using [[radiation]],<ref name="Dorlands">{{Citation |author=Elsevier |author-link=Elsevier |title=Dorland's Illustrated Medical Dictionary |publisher=Elsevier |url=http://dorlands.com/ |postscript=.}}</ref> that is, the destruction of precisely selected areas of [[tissue (biology)|tissue]] using [[ionizing radiation]] rather than excision with a blade. Like other forms of [[radiation therapy]] (also called radiotherapy), it is usually used to treat [[cancer]]. 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".<ref>{{cite journal | vauthors = Leksell L | title = The stereotaxic method and radiosurgery of the brain | journal = Acta Chirurgica Scandinavica | volume = 102 | issue = 4 | pages = 316–319 | date = December 1951 | pmid = 14914373 }}</ref>

In '''stereotactic radiosurgery''' ('''SRS'''), the word "[[stereotactic surgery|stereotactic]]" refers to a three-dimensional [[coordinate system]] that enables accurate correlation of a virtual target seen in the patient's diagnostic images with the actual target position in the patient. Stereotactic radiosurgery may also be called [[stereotactic radiation therapy|stereotactic body radiation therapy]] (SBRT) or stereotactic ablative radiotherapy (SABR) when used outside the [[central nervous system]] (CNS).<ref name=SBRT/>
