In an X-ray CT apparatus (1) and an X-ray CT method, the thickness of an inspection object is computed on the basis of the number of transmission X-rays in a specific energy range set by the upper and lower K-absorption ends of an X-ray contrast media acting as the inspection object, and a CT image is reconstituted on the basis of the computed thickness of the inspection object. These X-ray CT apparatus (1) and X-ray CT method can create the X-ray CT image stably independently of the magnitude of the inspection object and the X-ray tube voltage (or the energy distribution of the X-ray). |
