Abstract
An X-ray CT image reconstruction method includes turning a fan-shaped X-ray beam, which is thick and irradiated to a subject, about the subject, detecting projection data items concerning an X-ray beam, which is transmitted by the subject, with the X-ray beam turned by a plurality of successive angles of rotation, enhancing fan-beam data, which includes projection data items detected with the X-ray beam turned by the angles of rotation, so as to sharpen projection data contained in the fan-beam data and acquired along each projection line, producing parallel-beam data, which has values thereof defined along parallel projection lines, in relation to each angle of projection using the enhanced fan-beam data, and reconstructing an image using the parallel-beam data.
