Gamma Knife

What is the Gamma Knife?

Gamma Knife stereotactic radiosurgery is a non-invasive alternative to traditional brain surgery and radiation. It treats brain tumors without a knife, drugs or weeks of radiation. The treatment takes just one day so you can get back to your life sooner.

The Gamma Knife Perfexion is the gold standard of stereotactic radiosurgery, for benign and cancerous brain tumors and brain metastases.
