Radiographic imaging apparatus

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.

The apparatus includes: an X-ray source a multi slits element a first grating; a second grating; a driving section; a subject placing plate: and an X-ray detector, in which conversion elements to convert intensities of X-rays received thereby to electric signals, are arranged in a two-dimensional pattern so as to read the electric signals as image signals. The driving section moves the multi slits element relative to both the first grating and the second grating in a first direction orthogonal to a second direction of irradiating the X-rays, so that the X-ray detector repeats a processing for reading the electric signals converted from the intensities of X-rays received thereby, every time when the multi slits element moves at predetermined intervals so as to acquire the image signals representing Moire images captured at the predetermined intervals.

X-ray image capturing apparatus, X-ray imaging system and X-ray image creation method

Disclosed in an x-ray imaging device, which uses a Talbot-Lau interferometer, eliminates the effects on image quality of a reconstructed image that arises in such cases as when the direction of a multi-slit or each lattice slit is altered and imaging is performed, and provides reconstructed images favorable for diagnosis. When a plurality of moire images imaged with an imaging subject loaded onto a imaging subject stand () and a plurality of moire images imaged without the imaging subject are input, a control unit () of a controller () corrects signal value differences arising from variations in x-ray strength during imaging respectively between the plurality of moire images with the imaging subject and between the plurality of moire images without the imaging subject, and respectively creates a reconstructed image with the imaging subject and a reconstructed image without the imaging subject. Then, the control unit () creates a reconstructed image of the imaging subject for diagnosis by correcting, on the basis of the reconstructed image without the imaging subject, image unevenness in the reconstructed image with the imaging subject caused by heterogeneity in light distribution caused by the angle of rotation of the multi-slit.
