A radiation therapy technique that delivers radiation directly to the breast tumor while sparing the healthy tissue. Also called radiation surgery and stereotactic external beam irradiation.
A radiation therapy procedure that uses special equipment to position the patient and precisely deliver a large radiation dose to a tumor and not to normal tissue. This procedure does not use surgery. It is used to treat brain tumors and other brain disorders. It is also being studied in the treatment of other types of cancer, such as lung cancer. Also called radiation surgery, stereotactic external-beam radiation, stereotactic radiation therapy, stereotactic radiosurgery, and stereotaxic radiosurgery.
A technique based on the principle that a single or fractionated dose of radiation delivered precisely to a small area will arrest or kill the tumor, while minimizing injury to surrounding nerves and brain tissue and/or function
Treatment of abnormalities (usually brain tumors or vascular malformation) using focused radiation. The head is held still using a "stereotactic" headframe, and information from x-ray, CT or MRI images is used to choose a specific target to receive high-dose radiation treatment. The two most popular devices for performing radiosurgery are "linear accelerator" and "gamma knife," also called "stereotactic radiosurgery."

Conventional radiation treatment for cancer exposes tumors and surrounding tissue to repeated low doses of radiation over an extended period. Radiotherapy employs a single highly focused beam of radiation to perform tissue destruction. Stereotactic radiosurgery is an image-guided non-invasive procedure whereby multiple precisely targeted, highly focused beams of radiation intersect at the tumor location to deliver a large dose of radiation to the tumor or lesion with minimal radiation to adjacent normal tissue. Radiation is concentrated on the target by moving the energy source and firing from many directions or by simultaneously firing multiple beams from a static array of radiation sources.
The use of radiation devices to treat diseases and disorders without having to cut into tissue. Two examples of devices used in treating TN are Gamma Knife and Linac.
use of a highly focused beam of ionizing radiation to destroy small and discrete lesions.
A technique for treating brain tumors that cannot be reached with surgery. The doctor uses CT scans to target the tumor with high doses of radiation.
a type of therapeutic radiology treatment that uses very focused beams of radiation to treat cancer and other lesions in a one-session treatment.
surgery technique that uses radio waves to produce a pressureless, bloodless incision; can also be used to heat bleaching agents
Radiation therapy in which a large radiation dose is delivered to a target volume in a single treatment rather than in small fractions . The target volume may or may not be cancerous tissue. Radiosurgical treatments rely on tight localization of the radiation dose to minimize damage to non-target tissue.
See Stereotactic radiation therapy.
Use of a number of precisely aimed, highly focused beams of ionizing radiation to target a specific area.
Type of radiation therapy that focuses energy to a small area of a tumor, usually less than 3 to 4 centimeters in diameter. It does not involve surgery.
A radiation therapy technique that uses a large number of narrow, precisely aimed, highly focused beams of ionising radiation. The beams are aimed from many directions circling the head and meet at a specific point.
a treatment that attacks a tumor with beams of radiation.
Radiosurgery is a medical procedure which allows non-invasive brain surgery, i.e., without actually opening the skull, by means of directed beams of ionizing radiation. It is a relatively recent technique (1951), which is used to destroy, by means of a precise dosage of radiation, intracranial tumors and other lesions that could be otherwise inaccessible or inadequate for open surgery. There are many nervous diseases for which conventional surgical treatment is difficult or has many deleterious consequences for the patient, due to arteries, nerves, and other vital structures being damaged.
