Gamma Knife Perfexion at Rhode Island Hospital

One of the first gamma knife centers in the United States, the Gamma Knife Center at Rhode Island Hospital has been utilizing this lifesaving technology for more than 30 years, and has treated more than 4,500 patients during that time. Rhode Island Hospital’s Gamma Knife Center brings the power of “Perfexion” to patients. This new technology offers an enhanced level of precision and care for certain types of brain tumors or vascular malformations of the brain. 

The Gamma Knife Center at Rhode Island Hospital offers the Leksell Gamma Knife Perfexion, the most advanced stereotactic radiosurgery technology available. Design and software advances found in Perfexion offer significant enhancements compared to previous versions, including improved treatment accuracy and safety. Areas of the brain previously inaccessible are now treatable. Perfexion is a precise and powerful tool that provides hope to patients with certain brain tumors, vascular malformations and other neurologic disorders, such as trigeminal neuralgia, certain tremors and obsessive-compulsive disorder.

Patients undergo a noninvasive procedure that uses a single, high-dose radiation treatment to target small and medium-sized intracranial structures, while sparing nearby tissue.

What We Treat

Advancements in technology and proven outcomes have helped dramatically widen the scope of conditions being treated by the gamma knife. 

Over one million patients worldwide have undergone gamma knife surgery to treat the following conditions, among others:

Tumors

• Meningiomas
• Skull base tumors
• Metastatic tumors to the brain
• Pituitary tumors
• Acoustic neuroma/Vestibular schwannomas

Vascular Abnormalities

• Arteriovenous malformations (AVMs)

Tremors

• Trigeminal neuralgia
• Tremors
• Obsessive-compulsive disorder
