Gamma Knife Radiation

What is Gamma Knife?

Brain Surgery Without a Knife

Gamma Knife is an alternative to traditional brain surgery and whole brain radiation therapy for the treatment of complex, difficult brain conditions. Dr. Polin is fellowship trained in Gamma Knife treatment.


These procedures are completed at Legacy Good Samaritan Gamma Knife Center .

Gamma Knife is a non-invasive stereotactic radiosurgery instrument that involves no scalpel or incision – it is not a knife at all. Instead, Gamma Knife uses up to 201 precisely focused beams of radiation to control malignant and nonmalignant tumors, as well as vascular and functional disorders in the brain, without harming surrounding healthy tissue.

Patients are typically in and out of the hospital in a day’s time – and back to their normal routines soon after treatment. Gamma Knife radiosurgery may be used in place of, or in addition to, traditional surgery or whole brain radiation, depending on a patient’s diagnosis.
