In computerized tomography (CT), standard filtered backprojection tomogram reconstruction from two dimensional projection data acquired in a time sequential manner assumes no relative motion between the gantry and the patient's plane of interest during data acquisition. In a realistic situation, this condition may not he satisfied, resulting in motion artifacts in the reconstructed image. the authors propose to perform image reconstruction from the interpolated projection data corresponding to a single time instant, the mid-scan time. They present simulation results to illustrate the obtained reduction of motion artifacts.<>
