Stereotactic radiation therapy , also called stereotactic external-beam radiation therapy and stereotaxic radiation therapy , is a type of external radiation therapy that uses special equipment to position the patient and precisely send radiation to the 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 cancers, such as lung cancer. What distinguishes Stereotactic from conventional radiotherapy is the precision with which it is sent. There are several systems available, some of which use specially designed frameworks that are physically attached to the patient's skull while newer, more advanced techniques use highly accurate thermoplastic masks and imaging systems to locate patients. The end result is the delivery of high-dose radiation with sub-millimeter accuracy.
