ABSTRACT:
Tomographic images are obtained at a plane of interest by taking a series of x-ray exposures, producing a series of multiple images therefrom, arranging these multiple images so that points residing within a desired plane of interest are coincident to form a first order clarified image, repeating the step for a predetermined number of other planes which are parallel to the first plane of interest, to produce a first order clarified image for each of these planes, and then producing a smeared image for each of such planes, except one, by replicating the first order image for said plane a predetermined number of times and shifting each of the replicated images in the plane as a function of the distance between that particular plane and the x-ray source, the distance between that particular plane and the x-ray image device, the same distances but taken relative to a plane of interest, and the distance moved between exposures by the x-ray source. This smeared image for each particular plane is then multiplied by a coefficient and subtracted from the first order image of the plane of interest to form a second order clarified image of the plane of interest.
