Multi-slice X-ray CT apparatus and method of controlling the same



Multi-slice X-ray CT apparatus and method of controlling the same



Official Gazette of the United States Patent & Trademark Office Patents 1262(1), Sep 3



For the purpose of reconstructing a plurality of X-ray tomographic images having a plurality of practical slice thicknesses while reducing the number of X-ray detector arrays and simplifying configuration, X-rays generated by an X-ray tube 4 are emitted via a slit 15 of a collimator 6 toward a detector 8 disposed opposite to the X-ray tube 4; the length (width) of the collimator 6's slit 15 in the D1 direction and the position of the collimator 6 in the D1 direction are adjustable; the detector 8 is comprised of four X-ray detector arrays; and the widths of the two outer X-ray detector arrays in the D1 direction are larger than the widths of the two center X-ray detector arrays.
