Abstract: A medical image system includes an X-ray imaging device with a Talbot or Talbot-Lau interferometer, a reconstructed image generation unit, an extraction unit, a feature value calculation unit and a determination unit. The generation unit generates, among a differential phase image, an absorption image and a small-angle scattering image, at least the differential phase image based on an image signal obtained by the X-ray imaging device imaging a joint part. The extraction unit extracts a joint cartilage region based on the differential phase image. The calculation unit analyzes the joint cartilage region to calculate a feature value indicating a joint cartilage state. The determination unit compares the feature value with a predetermined reference value and determines, based on the comparison result, into which one of predetermined scores of multiple stages the joint cartilage state falls.

Abstract: A Talbot imaging apparatus includes a radiation source, a plurality of gratings, a capturing control unit, a radiation detector, a setting unit and an irradiation control unit. The radiation source irradiates radiation. The capturing control unit relatively shifts the plurality of gratings and performs control of capturing a plurality of Moire images of a subject to generate a reconstructed image. The radiation detector acquires a captured Moire image. The setting unit sets a capturing condition for capturing a second and further Moire images by making a capturing result of a first Moire image be a reference, or sets a capturing condition for the plurality of Moire images by making another Moire image captured before capturing the plurality of Moire images be a reference. The irradiation control unit controls irradiation of radiation from the radiation source based on the capturing condition set by the setting unit.

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.

Abstract: An equivalent phantom is used for an X-ray Talbot imaging apparatus which includes an X-ray source, a plurality of gratings and an X-ray detector. The apparatus captures at least a Moire image from which a differential phase image of an object is generated. The equivalent phantom includes a first substance having a first refractive index and a second substance having a second refractive index. A ratio of the first refractive index to the second refractive index is equal to a ratio of a refractive index of a soft tissue to a refractive index of a surrounding tissue. At least a part of a shape of one of the first and second substances is equal to a shape of a corresponding portion of the soft tissue.
