Abstract
According to an embodiment, a grid is provided between an X-ray generator and a flat panel detector. Processing circuitry configured to convert original image based on X-rays having passed through the grid and detected into a plurality of pieces of frequency band data, remove interference fringes contained in at least one piece of frequency band data among the pieces of frequency band data, reduce noise contained in the pieces of frequency band data, correct a scattered radiation of the original image based on a scattered radiation contained in the X-rays having passed through the grid and a scattered radiation contained in X-rays having passed through a grid that removes scattered radiation to a larger extent than the grid, and synthesize a plurality of pieces of frequency band data to generate image.
