Abstract
Abstract The present invention relates to a new and improved tomographic visualization apparatus and method. The apparatus includes a camera with a stationary collimator of a radiation dense material with channels therein for collecting radiation from a body which passes through the channels in the collimator. The radiation is thereafter detected and the signal information is processed so as to provide images of selected depths within the body. The stationary collimator includes a plurality of matching sections wherein, the center lines of the holes or channels in each sector are parallel to each other and the angular position of their center lines are at a sloping angle in relation to the surface plane of the scintillation crystal of the camera. The center lines of the channels in one sector are not parallel to the center lines of those of any other sector but slope toward the common plane of intersection along the camera axis to provide matching tomographic collimator sections. The images from the collimator sections are superimposed over one another in varying degrees to provide the reinforced images at varying depths.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
185 words
A tomographic visualization device comprising: a data processor means for providing accumulated information, a scintillation camera connected to said data processor for providing image data of radiation from a body to said data processor means, said camera including a detector connected to said data processor and a stationary collimator connected to said detector, said stationary collimator for collecting data from said body to provide tomographic data including, at least two sections each including a large number of channels, said channels in each section having longitudinal center lines generally parallel to each other; and all said channels of at least two sections of said collimator having longitudinal center lines at the same general angle in relation to a single reference plane for at least two sections of said collimator; said longitudinal center lines of the channels in each section intersect the longitudinal center lines of the channels of at least one other section at a large number of planes to reinforce the image at different distances from said stationary collimator, said camera and said body fixed in relation to one another during radiation image data collection.
Claim 2
Dependent Claim
185 words
A tomographic visualization device comprising: a data processor means for providing accumulated information, a scintillation camera connected to said data processor for providing image data of radiation from a body to said data processor means, said camera including a detector connected to said data processor and a stationary collimator connected to said detector, said stationary collimator for collecting data from said body to provide tomographic data including, at least two sections each including a large number of channels, said channels in each section having longitudinal center lines generally parallel to each other; and all said channels of at least two sections of said collimator having longitudinal center lines at the same general angle in relation to a single reference plane for at least two sections of said collimator; said longitudinal center lines of the channels in each section intersect the longitudinal center lines of the channels of at least one other section at a large number of planes to reinforce the image at different distances from said stationary collimator, said camera and said body fixed in relation to one another during radiation image data collection.
Claim 3
Dependent Claim
44 words
A tomographic visualization device as set forth in claim 1 including, a superimposition means connected to said camera to provide varying degrees of superimposition of data from each said section to provide reinforced data at particular depths in said body positioned from the camera.
Claim 4
Independent Claim
85 words
A method of providing reinforced images from a radiating body at a particular depth within said body by the steps of, simultaneously viewing radiation from a body from a plurality of positions, collimating the viewed radiation from each of said positions to provide a plurality of generally parallel beams of radiation, collecting images provided by each of the collimated beams, and superimposing a plurality of said images one upon the other to provide at least one reinforced image from a particular depth within the body.
Claim 5
Independent Claim
85 words
A method of providing reinforced images from a radiating body at a particular depth within said body by the steps of, simultaneously viewing radiation from a body from a plurality of positions, collimating the viewed radiation from each of said positions to provide a plurality of generally parallel beams of radiation, collecting images provided by each of the collimated beams, and superimposing a plurality of said images one upon the other to provide at least one reinforced image from a particular depth within the body.
