Stereotactic Radiosurgery

Stereotactic radiosurgery (SRS) is a non-invasive, non-surgical treatment option applied to tumors and lesions in difficult to reach or inoperable regions of the body (areas where danger of traditional surgery is too great). Prior to treatment, the patient undergoes MRI and CT scans, the images are then fed into a 3-D software program to simulate anatomical structure as well as the exact irregular shape of the tumor. The radiation oncologists with the help of radiation physicists and dosimetrists can then implement a treatment plan specifically individualized to each patient. The actual procedure then consists of the one-time application of multiple, highly focused beams of radiation which converge on a small area of abnormal tissue, while sparing the healthy tissue nearby. This technique is most commonly uses in areas such as the brain and spine cord
