<p>A method of collecting data to obtain correctly opposed view data as real data for every channel in an X-ray tomograph which uses fan beam X-rays. The timing for collecting output data from each detection channel is so selected that a relation holds true for all the detection channels, the relation being such that a pair of data based upon a pair of X-ray beams that penetrate in mutually opposite directions through a substantially common path formed in a subject are detected through a pair of detection channels that are located at substantially symmetrical positions relative to the center of the X-ray detector.</p> |
