What does this procedure involve?

Gamma Knife Radiosurgery is a non-invasive, single-session treatment that delivers highly focused beams of radiation to a precisely targeted brain lesion, such as a tumor smaller than 3 cm. Using stereotactic frame-based imaging, the system maps the lesion in 3D and directs up to 201 cobalt-60 sources to converge exactly on the target, sparing surrounding healthy tissue. The entire process—from frame placement to treatment—takes several hours, but you return home the same day with no incisions or general anesthesia required.
