PROBLEM TO BE SOLVED: To use a conventional method for helical interpolation and for removing a ring artifact in a computerized tomograph for generating the tomographic image of an inspection object inclined against the longitudinal axis of a bed device. SOLUTION: This computerized tomograph is provided with an X-ray source rotatable around a system axis Z and a detector system having many rows of detector elements, the X-ray source and detector system are fitted to a gantry 1, and the gantry 1 and a bed device 7 can be rocked relatively to each other so that the system axis Z and the longitudinal axis L of the bed device 7 are inclined relatively to each other in the rocked state. The bed device 7 and gantry 1 are made linearly position-adjustable relatively to each other at least nearly in the direction of the system axis Z in the rocked state to generate relative motion between the gantry 1 and bed device 7. |
