Intracranial stereotactic radiosurgery

The name Stereotaxis is derived from Greek “stereos” (fixed, 3-dimensional) and “taxis” (arrangement). Stereotactic irradiation is an irradiation technique, which enables to deliver the prescribed dose of ionizing radiation into localised volumes. Stereotactic radiosurgery performed by stereotactic targeting is based on precise 3D topometry of patients and subsequent (after the irradiation plan was calculated) computer-controlled radiosurgery using stereotactic equipment. Applied doses typically range from 12,0 – 35,0 Gy, the volume of planned targets is small, from 0,1 to 15 cm3. Stereotactic irradiation most often uses megavoltage X-rays and gamma irradiation 60Co.
