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.

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.

The image processing apparatus measures the thickness of cartilage in the joint in the differential phase image or an image generated from the differential phase image, by reference to at least one of i) an edge of a bone in the joint identified in a reconstructed image or an image generated from the reconstructed image and ii) an edge of the cartilage identified in the differential phase image or the image generated from the differential phase image.

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.

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.

Abstract: The present invention provides a method for displaying medical images and a medical image display system that do not require a medical practitioner to move his/her line of sight at the time of comparing/interpreting images and that can improve accuracy in diagnosis. According to the medical image display system of the present invention: an X-ray imaging device captures an image of a subject according to a first imaging mode by a fringe-scanning imaging device or a second imaging mode by a Fourier transform imaging device; a controller creates at least two images from among an X-ray absorption image, a differential phase image, and a small-angle scattering image on the basis of the captured moir image; and said at least two images that have been created are displayed in turn in the same position on a display section.

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.

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.
