X-ray diagnostic apparatus and image processing apparatus

An image processing apparatus comprising:

• processing circuitry configured to
• convert original image data based on X-rays having passed through a grid and detected by a flat panel detector 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 component of the original image data based on a scattered radiation component contained in the X-rays having passed through the grid and a scattered radiation component 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 after being processed by the respective processing units to generate image data.
