Stereotactic radiation therapy is a type of external radiation therapy that uses special equipment to position the patient and precisely deliver radiation to a tumor. The total dose of radiation is divided into several smaller doses given over several days. Stereotactic radiation therapy 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 stereotactic external-beam radiation therapy and stereotaxic radiation therapy. What differentiates Stereotactic from conventional radiotherapy is the precision with which it is delivered. The patient is held steady inside a metal frame, which is attached to their skull. This frame reduces the amount of movement errors that will occur during a treatment. As the precision of the treatment increases the amount of raditaion delivered can also be increased.
