The Gamma Knife radiosurgical unit has a number of significant differences:
• it is used only for irradiation of neoplasms and other pathologies inside the skull;
• Gamma Knife contains only 200 point sources of radiation, so a lower dose of radiation can be applied to the tumor, which makes it possible to destroy tumors no larger than 3 cm;
• during the irradiation session, the patient’s head is fixed to the table with the help of a special rigid frame (framework);
• only 1 irradiation session is performed, which lasts 2-3 hours.
At the same time, Gamma Knife remains the “gold standard” in the treatment of a number of brain tumors and a more affordable method of radiosurgery, due to the lower cost of the procedure.
