Patent Images
1. A stereotactic surgical beam localization apparatus disposed within a surgical microscope, the apparatus comprising:
- stereotactic surgical frame means;
objective lens means of said surgical microscope attached to said stereotactic surgical frame means;
beam emitting means comprising laser means disposed within said surgical microscope for emitting at least two beams through said objective lens means from two separate and spaced points;
means for movably adjusting the relative positions to one another of said beam emitting points;
means for aiming said beams at user selected locations on a selected volumetric entity of a body; and
means for ascertaining desired information about the selected volumetric entity of the body mathematically from the positions of said beam emitting means in said apparatus, the relative positions to one another of said beam emitting means, and the aiming directions of beams from the beam emitting points.

Abstract
The disclosure is directed to 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 light beams which, when they intersect, allow for such measurements and calculations. In one embodiment, the light sources attach to a stereotactic frame. In an alternative embodiment, the light sources are incorporated within a stereotactic microscope.
