Abstract: A radiation imaging system includes a radiation imaging device, a reconstruction unit and a detection unit. The reconstruction unit generates at least two of a differential phase image, an absorption image and a small-angle scattering image based on periodic pattern images of a subject obtained by the imaging device. The detection unit performs regression analysis on at least two images of (a) the differential phase image, a differential absorption image of the absorption image and a differential small-angle scattering image of the small-angle scattering image or (b) a phase image of the differential phase image, the absorption image and the small-angle scattering image; calculates a value of an indicator indicating a relationship between the at least two images; and detects image quality deterioration due to change in relative position of the imaging device and the subject based on the value.

Abstract: A medical imaging system creates three kinds of reconstructed images of a diagnosis target site in a subject through X-ray imaging of the diagnosis target site with a Talbot or Talbot-Lau imaging apparatus, the three kinds of reconstructed images being an absorption image, a differential phase image, and a small-angle scattering image. The medical imaging system includes: an input unit to receive an input of diagnosis target information for specifying the diagnosis target site, or the diagnosis target site and a disease to be diagnosed in the diagnosis target site; and a control unit to create a combined image of two kinds of reconstructed images among the three kinds of reconstructed images on the basis of the diagnosis target information input through the input unit, and to control a displaying unit to display the combined image.

Abstract: The X-ray imaging system of this invention includes: a detecting member which detects a salt and pepper noise region in the reconstructed image based on at least one characteristic value of the moire stripe image not including the object and/or the moire stripe image including the object; a masked-image generating member which generates a masked image for identifying the detected salt and pepper noise region; and an image processing member which masks or trims at least one of the reconstructed image and the moire stripe images with the generated masked image.

Abstract: A radiation capturing system includes the following. A radiation source, a plurality of gratings, and a radiation detector, are provided aligned in a radiation irradiating axis direction. A Talbot interferometer or a Talbot-Lau interferometer captures a moire fringe image for generating a reconstructed image. A low visibility capturing unit performs capturing of the moire fringe image with visibility of a moire fringe reduced more than in capturing of the moire fringe image for generating the reconstructed image. A generating unit generates an absorptive image based on the moire fringe image captured by the low visibility capturing unit.
