Gamma Knife Perfexion

Precise, Noninvasive Brain Surgery

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 20 years, and has treated more than 3,300 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. Rhode Island Hospital is the only center in Southeastern New England to offer gamma knife treatment.

The Gamma Knife Center at Rhode Island Hospital offers the Leksell Gamma Knife Perfexion, the newest and 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.

Gamma Knife PerfexionPerfexion 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 Can Treat

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

Over 700,000 and counting patients worldwide have undergone gamma knife surgery to treat the following conditions, among others:

Tumors

  • Meningioma
  • Metastatic tumors to the brain
  • Pituitary tumors
  • Acoustic neuroma

Vascular Abnormalities

  • Arteriovenous malformations (AVMs)
  • Cavernous angioma
  • Functional Disorders

Tremors

  • Trigeminal neuralgia
  • Obsessive-compulsive disorder
