PROBLEM TO BE SOLVED: To markedly reduce noise without giving damage to a detail structure in an image or time resolution, and to reduce a calculation cost for processing in the image data set flat surface.;SOLUTION: In a computer tomography imaging method, the step of scanning a test subject to detect at least two projection data sets which lag in terms of time within the same imaging area, the step of converting the projection data set to at least two conversion data sets within the position frequency area, the step of computing the time equilibrium value of the conversion data set for a part of the position frequency area and forming a new conversion data set by replacing the equilibrated value of the conversion data set with the computed equilibrium value, and furthermore comparing perfectly equal scanning lines, and the step of forming a new projection data set by inverse transformation of the new conversion data set, the step of reconfiguration of an image data set from the new projection data set, and the step of displaying the image data set.;COPYRIGHT: (C)2009,JPO&INPIT
