Stereotactic irradiation is a precise method for the delivery of focused radiation beams to small targets. Treatment can be administered in single or multiple fractions (radiosurgery or stereotactic radiotherapy, respectively). The field of intracranial stereotactic radiosurgery is rapidly advancing as a result of improvements in radiosurgical equipment, hardware, software design and better physician understanding of the clinical applications of stereotactic radiosurgery. This article reviews the technical basis of stereotactic radiosurgery as well as recent developments in this field.
