ABSTRACT
Stereotactic radiosurgery is a method of delivering high doses of ionizing radiation to small, well-defined intracranial targets. This technique differs from conventional radiotherapy, which involves exposing large areas of intracranial tissue to relatively broad fields of radiation over a number of sessions. This technology delivers highly focused convergent beams in a single session so that only the desired target is radiated, sparing adjacent structures. With major technological advances, the general role for radiosurgery as both an adjuvant and alternative to conventional neurosurgery has greatly expanded.
