PROBLEM TO BE SOLVED: To provide an X-ray tomograph capable of displaying dual energy images so as to be easily diagnosed by an operator. SOLUTION: The X-ray tomograph (10) is equipped with: an X-ray tube (101) for projecting an X-ray having a first energy spectrum and an X-ray having a second energy spectrum different from the first energy spectrum to a subject; an X-ray detection part (103) for detecting the X-ray of the first energy spectrum and the X-ray of the second energy spectrum projected to the subject; an image reconstruction means (23) for reconstructing a first image and a second image on the basis of the X-ray of the first energy spectrum and the X-ray of the second energy spectrum; a dual energy image generation means (25) for generating the dual energy image from the first image and the second image; and a display (60) for displaying at least either the first image or the second image and the dual energy image.
