Abstract
First ROI pixel values of a first region of interestof a radiographic intensity distribution image, and second ROI pixel values of a second region of interestof the radiographic intensity distribution image, are acquired. One of the first and second regions of interest is set to be at a position, or vicinity thereof, where a phase difference in the intensity modulation period within the radiographic intensity distribution image, with respect to the other region of interest, becomes π/2. Next, an elliptical locus obtained by plotting the first and second ROI pixel values for each radiographic intensity distribution image is determined. k angle region images are then acquired using the radiographic intensity distribution images corresponding to at least k angle regions that have been obtained by dividing the elliptical locus for each given angle. A radiographic image is then generated using the k angle region images. k is an integer of three or more.
