stereotactic radiation therapy


A type of external radiation therapy that uses special equipment to aim high-energy radiation beams at a tumour from different directions.

Stereotactic radiation therapy is used to treat tumours in the brain and other parts of the body. A special frame is used to make sure the person receiving treatment does not move and to ensure that radiation is delivered to exactly the same place during each treatment.

Stereotactic radiation therapy may be delivered as stereotactic radiosurgery or stereotactic radiotherapy.

Also called stereotactic external-beam radiation therapy and stereotaxic radiation therapy.
