How It Works

The Leksell Gamma Knife® Perfexion emits finely focused beams of gamma radiation with minimal effect on surrounding normal tissue and without the usual risks of surgery or an incision. Gamma Knife Perfexion maximizes patient comfort and can be used to treat lesions that before were either inaccessible or were treated unsuccessfully by conventional surgery, chemotherapy and/or radiation therapy.
The Leksell Gamma Knife® Perfexion offers unparalleled accuracy and precision, allows planning with all stereotactic and non-stereotactic image modalities (e.g., CT, MR, PET), and maximizes patient comfort.
