An advanced form of stereotactic or focused radiosurgery for benign processes and metastatic brain tumors that were previously considered inoperable or very high risk for conventional brain surgery. The "knife" is formed by 201 intersecting beams of gamma radiation that deliver a concentrated dose to a precise area of the brain.
The Gamma Knife uses older radiation technology that is confined to treating tumors in the head. The Gamma Knife uses ionizing radiation (gamma rays) produced by 201 cobalt-60 sources to target the tumor or abnormality.
A type of radiation therapy which uses high doses of gamma radiation aimed at tumors instead of a scalpel. Often used in the treatment of brain tumors.
a medical device capable of delivering an extremely accurate dose of radiation used in the treatment of lesions, tumors and other brain abnormalities
The gamma knife is a radiosurgical machine that contains 201 separate radioactive cobalt sources. The radiation beams from each source (gamma rays) are focused together at the tumor.
a device for performing radiosurgery using radioactive Cobalt sources of irradiation. The patient's head is placed in a frame screwed to the skull using local anesthetic, and radiation is given in a single treatment using several hundred radioactive sources configured in a dome shape and focused on a single point (the tumor).
A non-incision surgical device that uses Gamma radiation to cause precisely aimed damage to targeted tissue. Used to create lesions on the root of the trigeminal nerve.
The Gamma Knife is the original radiosurgery technology, which by design is restricted to treating brain tumors. This device uses ionizing radiation (gamma rays) produced by 201 radioactive cobalt-60 sources to ablate intracranial targets.
Equipment that precisely delivers a concentrated dose of radiation to a predetermined target using gamma rays.
a type of radiosurgery that uses gamma rays to treat brain cancer.
A noninvasive, bloodless technology that delivers concentrated gamma radiation to targets in the brain such as tumors and other abnormalities.
A non-surgical procedure in which a machine that emits hundreds of powerful, highly focused gamma beams is aimed at a tumor in a single treatment session, as in treatment of a brain tumor.
A method of single-session radiation therapy in which high-energy rays eradicate brain tumor cells as they hit the tumor from many angles.
Radiation therapy in which high-energy rays are aimed at a tumor from many angles in a single treatment session.
A type of highly focused radiation therapy.
Type of stereotactic radiation designed to deliver radiation from multiple cobalt sources, computer-focused to a small area or multiple small areas.
A cobalt-60 based radiation therapy machine used to treat brain tumors and abnormalities. The Gamma Knife delivers 201 beams of highly focused gamma rays to the treatment site.
In medicine, Leksell Gamma Knife is a neurosurgical device used to treat brain tumors. It was invented by Lars Leksell, a Swedish neurosurgeon, in the 1950s.
