Gamma Knife Stereotactic Radiosurgery

The Yale New Haven Gamma Knife is the only radiosurgery unit in Connecticut dedicated to the treatment of head and neck conditions.

The Principle

Stereotactic radiosurgery is the delivery of a high dose of highly focused radiation in a single session to treat specifically chosen intracranial targets. At Yale, this treatment is delivered using a Gamma Knife. Originally designed by Dr Lars Leksell in Sweden, this machine contains 192 cobalt-60 radiation sources arranged in a hemispherical array and housed in a heavily shielded unit. Using the Gamma Knife, radiation is precisely focused to deliver the high dose of radiation only to the designated target while sparing the surrounding tissues. Complex shaped lesions can be treated by combining varying-sized collimators with selected beam blocking and dose weighting using sophisticated computer planning software. This ensures that each patient's lesion(s) receive a tightly conformal "tailored" radiation treatment plan, while avoiding surrounding normal structures.
