  • Publication number: 20200249179
    Abstract: A higher accuracy beam hardening correction with a low calculation load is performed with objects whose elements have a wider range of effective atomic numbers Zeff, thereby contributing to presentation of more quantitative X-ray images. Of two or more X-ray energy bins, two X-ray bins are selected to normalize X-ray attenuation amount ?t in those bins such that one or more normalized X-ray attenuation amounts are obtained at each pixel areas. From reference information indicating a theoretical relationship of correspondence between the normalized X-ray attenuation amounts and effective atomic numbers of elements, one ore more effective atomic numbers are estimated every pixel area. Among the one or more effective atomic numbers (ZHigh, ZLow) and an effective atomic number (Zm) preset for the beam hardening correction, two or more atomic numbers are subjected to their equality determination.

This array has a row direction oblique to a scan direction. When viewing in the scan direction, a pixel group is provided solely or repeatedly, the pixel group being composed of “M rows × N pieces” of pixels (M is a positive integer equal to or larger than 1, N is a positive integer equal to or larger than 2, and M and N have a relationship of prime numbers). The pixel group occupies a quadrangle whose diagonal line is parallel with the scan direction. In a memory space, the frame data from the pixels are converted to frame data in a Cartesian coordinate system having a row direction which is in parallel with the scan direction and a column direction orthogonal to the row direction.

  • Patent number: 10502698
    Abstract: The type and/or properties of a substance included in an object is identified highly accurately regardless of the thickness of the substance. A data processing apparatus processes counts detected at each of pixels of a photo counting detector in each of a plurality of energy ranges of X-rays. The X-rays are radiated from an X-ray tube, and transmitted through an object. The apparatus calculates an image of the object based on the counts, and sets a region of interest on the image. The apparatus further removes, from the image, pixel information showing a background present in the region of interest, and calculates, pixel by pixel, inherent information inherent to the substance, based on the counts detected at each of the respective pixels in each of the energy ranges of the X-rays in the region of interest. The inherent information indicates a transmission characteristic inherent to the X-rays.

  • Publication number: 20190162679
    Abstract: In a data processing apparatus, image data are calculated based on photon counts of an X-ray beam transmitted through an object. Based on the image data, X-ray attenuation information is calculated. The attenuation information includes i) inherent information inherently depending on a type or a property of the object, the inherent information being indicated by a quantity of a vector in an n-dimensional coordinate whose dimension is equal in number to the n-piece energy ranges; and ii) associated information being associated with the inherent information and depending on a length of a path along which the X-ray beam passes though the object. From the attenuation information, only the inherent information is produced which is independent of the associated information. Scattering points corresponding to the inherent information are calculated to be mapped in the n-dimensional coordinate or in a coordinate whose dimension is less than the n-dimensional coordinate.
