A method for performing scattered radiation correction. The position of a collimator and the width of a slit are adjusted so that direct radiation will fall on one of a plurality of arrays of detectors. A predetermined phantom is scanned. The scan is performed relative to each of the plurality of arrays of detectors. Based on data detected during each scan, scattered radiation correction data is produced. The produced scattered radiation correction data is used to correct projection data acquired by scanning a subject.
