AMS Chairman and Chief Executive Officer Ernest A. Bates, M.D., said, "This Perfexion system, our 28th new Gamma Knife site, makes it possible for patients at PeaceHealth Sacred Heart Medical Center to benefit from this advanced therapeutic technology. We are pleased to offer the latest advances in stereotactic radiosurgery to cancer patients throughout the Willamette Valley."

The Gamma Knife Perfexion, manufactured by Elekta, maintains full clinical compatibility with the classic Gamma Knife and is supported by efficacy and outcome data from 600,000 treated patients worldwide and thousands of peer-reviewed scientific articles, making it a proven choice for radiosurgery of the brain.

Elekta estimates that the fully automated and efficient single push-button approach can save 3-5 working weeks of physician time per year at an average Gamma Knife center.
