Claim One:
1. A method of computerized tomography comprising the steps of: (a) generating imaging energy; (b) passing the imaging energy through an object of interest; (c) using an array detector having non-square elements to detect said imaging energy as attenuated by passage through the object of interest to provide asymmetric projection data corresponding to an asymmetric grid in which at least a portion of the object of interest is disposed; (d) converting said asymmetric projection data into distorted projection data which is symmetric corresponding to a symmetric grid, said distorted projection data representing projection data which would be obtained upon subjecting said portion of said object of interest to a distorting transformation which transforms said asymmetric grid into said symmetric grid; (e) Generating distorted reconstruction image data by application of image reconstruction in symmetric geometry using said distorted projection data; and (f) converting said distorted reconstructed image data into asymmetric reconstructed image data by correcting for distortions introduced by the converting from asymmetric projection data into distorted projection data.
