An X-ray tube generates X-rays. An X-ray detector detects X-rays generated by the X-ray tube and transmitted through a subject. A storage unit stores data of a gullet image associated with a gullet of the subject. An X-ray image generation unit generates data of an X-ray image based on an output from the X-ray detector during catheter operation. The X-ray image is associated with a left atrium located anatomically near the gullet. A display control unit displays a gullet region of the gullet image together with the X-ray image on the display device while superimposing the gullet region on the X-ray image to allow visual recognition of a distal end portion of a catheter region included in the X-ray image. |
