Perfexion Gamma Knife

GammaKnife1Perfexion is the newest radiosurgery system available to patients for treatment of brain tumors and brain disorders. It is a radiosurgeon’s tool dedicated to treat the brain and upper spine and neck.

Perfexion has become the new gold standard for cranial radiosurgery, providing a level of accuracy and precision in the treatment of brain tumors, vascular malformations, acoustic neuromas, trigeminal neuralgia and other brain disorders that is superior to any other radiosurgery system. At the same time, the radiation dose to normal brain and to other parts of the body is far lower than any other radiosurgery system. Doses of radiation can be delivered to multiple target areas in one session, avoiding the need to move the patient or adjust the machine. This reduces the time a patient has to spend undergoing treatment.

The painless treatment is usually performed on an outpatient basis and requires no general anesthesia. Most patients resume normal activities within a day of treatment.


With Perfexion’s wider application range of advanced Gamma Knife radiosurgery, there is improvement in the quality of life for many more patients with serious neurological conditions. The same as with any of the Gamma Knife models, Perfexion’s unmatched combination of power and precision has resulted in positive clinical outcomes with few complications.

Gamma Knife is the Gold Standard of radiosurgery systems as documented in more peer-reviewed medical literature than all other systems combined.

San Diego Gamma Knife Center is the only medical facility in San Diego County providing this effective treatment option for patients with brain disease.
