PROBLEM TO BE SOLVED: To photograph two kinds of tomographic images different in an X-ray energy through the use of one kind of X-ray detector without changing-over an X-ray tube voltage. SOLUTION: The energies of the X-ray to be respectively made incident to the front half channel and the rear half channel of a multi-channel X-ray detector (106) are made to be mutually different (150, 160). Respective kinds of mirror point data are generated based on X-ray detection data of the front half channel and X-ray detection data of the rear half channel which are obtained by rotation of 360°. The first kind of tomographic image and the second kind of tomographic image are respectively re-constituted, based on the combination of the X-ray detection data of the front half channel with the mirror point data and the combination of the X-ray detection data of the rear half channel with the mirror point data.
