Abstract
Abstract A method and apparatus for determining, in three dimensions, the location, size, depth and width of tumors, lesions, abnormalities, structures, and the like, particularly useful for stereotactic surgery. The invention utilizes several energy beams which, when they intersect, allow for such measurements and calculations. In one embodiment, the energy sources attach to a stereotactic frame. In an alternative embodiment, the energy sources are incorporated within a stereotactic microscope. Either embodiment may be mounted on an articulated robotic type arm.
