<p>A computerized tomography apparatus is disclosed which reconstructs a tomography image of data from multi-directional projection data in a period of time less than the time required for a scan operation for data acquisition and displays the tomography image after a lapse of a given period of time from the termination of the scan operation. This avoids the time interval between scan and image display becoming irregular. Accordingly, tomography images can be displayed successively like motion picture to observe the internal movements of a section of a human body under examination in real time. <IMAGE></p>
