Gamma Knife Perfexion

Also known as: Gamma Knife

Stereotactic radiosurgery is the most precise type of radiation therapy delivery available with accuracy within 1mm. Radiosurgery is typically used for benign and malignant lesions inside the skull including meningioma, trigeminal neuralgia, vestibular schwannoma and cases where cancer has spread to the brain.

The Gamma Knife Center of Oregon's medical director, Steven Seung, M.D., Ph.D., FACR says Gamma Knife Perfexion is revolutionary. "Imagine going from a four-cylinder stick-shift, two-wheel-drive compact car to an eight-cylinder automatic, all-wheel-drive, full-size car. That's what it's like going from the current Gamma Knife to the Perfexion."

Gamma Knife is one of the most advanced radiosurgical tools available to treat a variety of benign and malignant brain lesions and disorders, including brain cancers. An alternative to invasive surgery, Gamma Knife Perfexion used at the Gamma Knife Center of Oregon focuses 192 independent beams of radiation on a single, precisely targeted location. With pinpoint accuracy, Gamma Knife can destroy tumors with no incisions and minimal damage to surrounding healthy tissue.
