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.

Abstract: An X-ray imaging apparatus is capable of cutting the time needed for the long-length image. A candidate point registration element 25 registers an end of a long-length region as a candidate point. A start location determination element 27 determines the candidate point closest to the present location of the imaging system as the imaging start location based on the distance between the present location of the imaging system and each candidate point. A distance that the imaging system shifts at the imaging preparation step of the X-ray images by determining the imaging start location prior to imaging of a series of X-ray images that form a long-length image can be shortened. When the long-length imaging is implemented multiple times, the shift-distance of the imaging system is further shortened by updating the setting of the imaging start location in advance every time when a series of X-ray images is taken, so that the time needed for the entire steps relative to the long-length imaging can be largely cut.

Abstract: In an X-ray imaging device according to a first embodiment, an X-ray detector has a configuration in which scintillator elements are defined by light-shielding walls in a lattice shape. Among X-rays incident on the X-ray detector, X-rays incident on the light-shielding walls are not converted into scintillator light and are transmitted by the X-ray detector. Accordingly, by causing X-rays to be incident on the X-ray detector in which the scintillator elements are defined by the light-shielding walls in a lattice shape, an area in which X-rays 3a transmitted by a subject M are incident on the X-ray detector can be limited to an arbitrary range. Accordingly, since a detection mask can be omitted in the X-ray imaging device which is used for EI-XPCi, it is possible to reduce a manufacturing cost of the X-ray imaging device.
