Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
140 words
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.
Claim 2
Dependent Claim
140 words
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.
Claim 3
Dependent Claim
30 words
The invention of claim 1 wherein said beam emitting means further comprises prism means disposed within said surgical microscope, wherein said prism means comprise said two separate and spaced points.
Claim 4
Dependent Claim
19 words
The invention of claim 1 wherein said beam emitting means are disposed in a spherical relationship to one another.
Claim 5
Dependent Claim
15 words
The invention of claim 1 wherein said beam emitting means further comprises laser diode means.
Claim 6
Dependent Claim
18 words
The invention of claim 1 wherein said beam emitting means further comprises single laser and fiber optic means.
Claim 7
Dependent Claim
41 words
The invention of claim 1 wherein said means for ascertaining desired information comprises means for proportionally angulating the positions and the beam aiming directions of said beam emitting means at a selected point to determine positional information about the selected point.
Claim 8
Dependent Claim
58 words
The invention of claim 1 wherein said means for ascertaining desired information comprises means for repeatedly proportionally angulating the position and the beam aiming direction of said beam emitting means at a series of selected points about an area to be measured of the volumetric entity to determine positional and area information about the area to be measured.
