Stereotactic Radiation Therapy on Intracranial Structures Using an LUÉR-20M Medical Linear Accelerator

A system for stereotactic radiation therapy using narrow bremsstrahlung beams for pathological and normal intracranial structures is examined. The system is based on an LUÉR-20M medical linear accelerator.The method is based on stereotactic centering of a small intracranial target using an x-ray centering guide and rigidly securing the patient's head, with no bleeding, on a treatment table using a rapidly solidifying individual plastic mask, isocentric movement of the treatment table toward the linear accelerator, and subsequent treatment with a narrow static or rotating photon beam. One hundred patients have been treated. The results show that this treatment method is effective.Stereotactic photon beam therapy can be an alternative method to surgery and treatment with a photon beam.
