  • Patent number: 9855018
    Abstract: Provided are a diagnostic medical image system and the like which enable diagnostic medical images generated in either an imaging system used for general imaging or an imaging system which includes a Talbot imaging device to be accurately associated with imaging order information. In the diagnostic medical image system, a controller groups a plurality of types of diagnostic medical images reconstructed and generated on the basis of a plurality of image signals captured by a second imaging system equipped with a Talbot imaging device and transmits the group to a console; and the console associates one diagnostic medical image generated from one image signal acquired from a first imaging system equipped with an X-ray imaging device with the imaging order information corresponding thereto and, by the same associating method, associates the grouped plurality of types of diagnostic medical images transmitted from the controller with the imaging order information corresponding thereto.

  • Patent number: 9665950
    Abstract: An X-ray imaging system includes an X-ray imaging device and an image processing device including a reconstruction unit and an estimation unit. The X-ray imaging device uses a Talbot or Talbot-Lau interferometer including gratings disposed in a line. The X-ray imaging device obtains sets of moire fringe images by fringe scanning multiple times between which arrangement of the gratings is changed. In the fringe scanning, one of the gratings is moved relatively to the remaining grating. The reconstruction unit generates, on the basis of the sets, a reconstructed image which is a differential phase image, an X-ray absorption image and/or a small-angle scattering image. The estimation unit estimates, on the basis of the reconstructed image, a relative position of the moved grating from a reference position of the grating at each imaging in the fringe scanning.

  • Patent number: 9025725
    Abstract: 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.

  • Patent number: 8989474
    Abstract: 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 (13) and a plurality of moire images imaged without the imaging subject are input, a control unit (51) of a controller (5) 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.

  • Publication number: 20140198895
    Abstract: A medical imaging system includes a radiographing apparatus and an image processing apparatus. The radiographing apparatus is provided with a Talbot or Talbot-Lau interferometer and includes an X-ray source, an X-ray detector, and a subject table. The image processing apparatus generates at least one of an X-ray absorption image, a differential phase image, and a small-angle scattering image of the subject using an image signal and a background signal obtained through subject radiographing and background radiographing, respectively. The background radiographing is performed with a member held instead of the subject. The member has a material and/or thickness to create change in energy spectrum of X-rays equivalent to change in energy spectrum of X-rays created by the subject.
