Describe stereotactic radiosurgery
What will be an ideal response?
Stereotactic radiosurgery (gamma knife surgery) is a noninvasive technique that is currently used to treat brain tumors in a one-day session. The use of the gamma knife for brain surgery has grown exponentially over the last few years. It is appropriate for brain tumors because the head can be completely immobilized. Radiosurgery can be performed by a modified linear accelerator, which rotates around the patient's head and delivers blasts of radiation to the tumor, or by a gamma knife.
