What is Stereotactic Radiosurgery (SRS)?
Stereotactic radiosurgery is a minimally invasive approach for treatment of benign and malignant brain tumors and other brain disorders, such as arteriovenous malformations, pituitary tumors, trigeminal neuralgia and some cases of tremor and severe pain. SRS involves computer-guided, extremely precise delivery of high doses of radiation to the targeted area of the brain. By avoiding open craniotomy in appropriate patients, radiosurgery decreases risks as well as recovery time. SRS is typically an outpatient procedure allowing patients to resume normal activities immediately. Currently the most widely used systems for SRS are the Linear Accelerators, CyberKnife and Gamma Knife. CyberKnife may also be used for radiosurgical treatment of tumors of the spine and other organs, such as lungs and prostate.
