Gamma Knife Radiosurgery

The Gamma Knife is a painless and non-invasive radiation device that delivers focused and highly accurate beams of radiation to the area of the brain requiring treatment.

One of the most advanced forms of stereotactic radiosurgery, the Gamma Knife is widely considered the gold standard for treatment of:

  • malignant and benign brain tumors and lesions,
  • arteriovascular malformations,
  • certain functional disorders, and
  • trigeminal neuralgia.

About the treatment
An external frame is fixed to the patient's head and an MRI is obtained. These images are used to create the 3D images in the stereotactic system to ensure accurate identification of the area to be treated and precise delivery of the radiation to the target.

The neurosurgeon, radiation oncologist, and medical physicist use highly sophisticated computer software to determine the size, location, and shape of the area to be treated. The Gamma Knife uses 192 radioactive sources to precisely direct beams of radiation to the specific target while sparing surrounding tissue.

After treatment is completed, the patient is monitored for a short time to ensure there are no immediate complications. The patient is able to go home the same day.
