摘要

PROBLEM TO BE SOLVED: To efficiently generate subtraction images by dual energy subtraction.SOLUTION: An X-ray image generation unit 11b alternately generates X-ray images obtained by X-ray irradiation having high energy and X-ray images obtained by X-ray irradiation having low energy. A dual energy subtraction image generation unit 11c generates a dual energy subtraction image using the X-ray image generated this time and the X-ray image generated last time, every time when the X-ray image is generated by the X-ray image generation unit 11b.
