PROBLEM TO BE SOLVED: To provide X-ray equipment adaptable when there is movement of natural respiration or body motion. SOLUTION: A mask image/marker image acquisition part 23b acquires a mask image and a subtraction image of a subject, with injection of a contrast agent, irradiated with X rays of different energy. A live image/marker image acquisition part 23c acquires a live image and a subtraction image of the subject, without injection of the contrast agent, irradiated with X rays of different energy. Then, a marker image collation adjusting part 23d adjusts a combination of the mask image and live image by collating a characteristic region of the subject specified on the subtraction image acquired by the mask image/marker image acquisition part 23b with a characteristic region of the subject specified on the subtraction image acquired by the live image/marker image acquisition part 23c.
