Abstract

Because of geometrical limitations in the helmet of the Leksell Gamma Knife™ (Elekta Corp., Atlanta, GA, USA) certain regions within the cranium cannot be targeted for treatment. We describe a method by which lesions in these regions can be treated with the Varian-Zmed stereotactic radiosurgery system utilizing an infrared optical positioning system attached to a Leksell head frame. We have measured the accuracy of the optical tracking system using a phantom attached to a Leksell frame and have determined that the system can target a linear accelerator radiosurgery beam to an accuracy of within 1 millimeter.
