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 beams which, when they intersect, allow for such measurements and calculations. The beam sources attach to a stereotactic frame.
