A revolution in advanced radiation treatment.
What is Gamma Knife?
Gamma Knife is an advanced, noninvasive treatment method that uses extremely precise beams of radiation to pinpoint tumor deposits, leaving the surrounding healthy tissue unharmed. Today, children and adults with a variety of neurological conditions and vascular malformations can take advantage of this breakthrough technology in a single session, with no overnight stay required.
Despite its name, Gamma Knife is not a blade at all; rather, a means of targeting highly precise radiation to abnormalities as small as 1/8 inch in diameter. In the experienced hands of expert Holy Spirit physicians, this treatment can effectively help with a wide variety of disorders, including brain tumors, epilepsy and other abnormalities that can cause chronic pain. It minimizes the amount of radiation risk to the normal brain and is perfect for surgery in areas of the brain where surgery would otherwise be dangerous.
As with all advanced technologies at Holy Spirit, the patient is assessed and supported through the procedure by a broad team of highly skilled, compassionate professionals, including oncologists, neurosurgeons and specialized nursing staff. This state-of-the-art treatment is just another way Holy Spirit–A Geisinger Affiliate is caring for you.
