  • Patent number: 10697904
    Abstract: An X-ray apparatus includes a two-dimensional pixel array having rectangular pixels outputting an electrical signal responsively to an incident X-ray photon. 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: 10539516
    Abstract: Frame data of tomographic planes that are parallel in the scan direction and between an X-ray tube and an X-ray detecting unit is generated based on detected frame data. The generation of frame data is based on the fan-shaped spreading of an X-ray beam and the differences in position in a height direction between the tomographic planes from a detection surface. Tomographic images are respectively generated from the frame data of the tomographic planes based on laminography technique. Edge information based on the changes in pixel values in each tomographic image is calculated for each pixel. A three-dimensional distribution of the edge information is generated and the edge information is searched in a direction passing through the tomographic planes and pixels indicating a maximum value in the edge information are detected. Only pixels in the tomographic images that positionally correspond to detected pixels are combined into a single composite image.

  • 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.

    Abstract: A drive device includes a control unit with a substrate. The control unit is disposed on an opposite side of a motor relative to an output shaft of the motor. The substrate has electronic components mounted on the substrate. A motor line connects the substrate and a winding. A frame member bears the surface-mount electronic components on a first surface of the substrate. A bearing holder holds a bearing that bears a shaft. A motor line takeout part allows the motor line to extend toward the control unit. A partition wall separates the shaft and the control unit at a radial inside position of the motor line takeout part. Such a structure prevents foreign matter from intruding into a control unit accommodating space.
