Pioneers in Radiosurgery

In 1997, Barrow Neurological Institute became the first institution in Arizona to offer Gamma Knife radiosurgery. Then, in 2003, we became the first center in the Southwest to implement CyberKnife. This new technology allowed us to broaden the scope of patients eligible for radiosurgery at the Institute, as CyberKnife is not limited to lesions of the skull. Lastly, in 2019, Barrow made headlines as the first institution in the world to treat a patient using the ZAP-X gyroscopic radiosurgery system.

High Patient Volume

The Department of Radiation Oncology at Barrow treats more than 1,000 neurological patients each year. Our state-of-the art Gamma Knife & Radiosurgery Center is one of the busiest in the country, treating nearly 400 patients annually with the Gamma Knife system alone.

Team of Experts

The Gamma Knife & Radiosurgery Center is home to world-class radiation oncologists, neurosurgeons, and neuro-otologists who are trained in radiosurgery. Because vascular abnormalities and tumors may require a combination of treatments, these experts also work together on each patient’s treatment plan.


Barrow Neurological Institute is dedicated to advancing the treatment of neurological diseases through research. This includes basic, translational, and clinical neuroscience research in tumors and vascular abnormalities.
