MULTI-SLICE X-RAY CT APPARATUS AND METHOD OF CONTROLLING THE SAME |
摘要 |
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. |
