An X-ray absorptance map associated with an object to be examined is generated on the basis of scanogram data obtained from a predetermined direction of the object, and imaging conditions are determined on the basis of the absorptance map. Before tomography, an index representing a radiation dose in the execution of scan in accordance with the imaging conditions is calculated and displayed, together with the imaging conditions. Every time the imaging conditions are changed, an index representing a radiation dose is calculated and displayed. Tomography is executed in accordance with the finally determined imaging conditions. This makes it possible to reduce the radiation dose to the object and obtain a tomographic image with high quality.
