  • Patent number: 10357221
    Abstract: A method for calibrating detectors in a CT scanner, wherein the new calibration process uses a combination of slab-based and water-based calibrations. By combining both calibrations, the complexity of each procedure can be reduced which will reduce restrictions on the quality of detectors used in the scanner. The slabs can be made out of commercially available material such as acrylic, and they will require no special treatment. Combining both calibrations also reduces the number of water phantoms needed for the calibration and the complexity of the calibration algorithm. Furthermore, the slabs can be shaped based on the scanner geometry so as to optimize the slab-based calibration step.

  • Patent number: 10335111
    Abstract: A center position of a female connector is located near to a rear surface of a housing compared with a center position of the housing in a thickness direction of the housing of an electronic cassette. An inclined surface, which is inclined relative to a side surface and the rear surface of the housing, is formed between the side surface and the rear surface. The female connector is formed on the inclined surface. Therefore, it is possible to attach an outer grid provided with a longer side panel to the housing, in comparison with the case where the center position of the female connector is made coincident with the center position of the housing in the thickness direction of the housing, without requiring any processing.

  • Patent number: 10222709
    Abstract: A pattern is applied to a substrate by a lithographic apparatus as part of a lithographic manufacturing system. Structures are produced with feature sizes less than 10 nm. A target includes one or more gratings with a direction of periodicity. A detector captures one or more diffraction spectra, to implement small angle X-ray scattering metrology. One or more properties, such as linewidth (CD), are calculated from the captured spectra for example by reconstruction. The irradiation direction defines a non-zero polar angle relative to a direction normal to the substrate and defines a non-zero azimuthal angle relative to the direction of periodicity, when projected onto a plane of the substrate. By selecting a suitable azimuthal angle, the diffraction efficiency of the target can be enhanced by a large factor. This allows measurement time to be reduced significantly compared with known techniques.
