PROBLEM TO BE SOLVED: To substantially eliminate an alignment error among an X-ray tube, an X-ray detector and a slitting device. SOLUTION: This X-ray computerized tomograph includes: an X-ray tube 11 which generates X-rays toward a subject in an imaging area; a slitting device 12 disposed between the X-ray tube and the imaging area and adapted for adjusting the thickness of the X-ray in a slicing direction; an X-ray detector 15 opposed to the X-ray tube across the imaging area for detecting the X-rays transmitted through the subject; and a computer for reconfiguring tomogram data on the basis of the output of the X-ray detector. The slitting device 12 has two shield plates 13, 14 arranged side-by-side in the slicing direction and supported by a support mechanism in such a way as to be individually movable along the slicing direction and be individually tiltable in the slicing direction.
