The X-ray image generation device according to the present invention is provided with an X-ray tube that has first focal point positions and second focal point positions, an X-ray detector, a focal point position control circuit that switches the focal point positions, an irradiation energy switching means that switches the X-ray irradiation energy level, an image processing circuit that generates X-ray images on the basis of the output of the X-ray detector and a storage device that retains a focal point position switching pattern and an X-ray irradiation energy switching pattern, wherein the X-ray irradiation energy switching pattern is configured such that the ratio of the number of the first focal point positions to the number of the second focal point positions in the focal point position switching pattern is the same as the ratio of the number of the first focal points to the number of the second focal points in the X-ray irradiation energy level. |
