  • Patent number: 10335104
    Abstract: A multi energy, such as dual-energy (“DE”), x-ray imaging system data acquisition and image reconstruction system and method enables optimizing the image contrast of a sample. Using the DE x-ray imaging system and its associated user interface applications, an operator performs a low energy (“LE”) and high energy (“HE”) x-ray scan of the same volume of interest of the sample. The system creates a low-energy reconstructed tomographic volume data set from the set of low-energy projections and a high-energy tomographic volume data set from the set of high-energy projections. This enables the operator to control the image contrast of selected slices, and apply the information associated with optimizing the contrast of the selected slice to all slices in the low-energy and high-energy tomographic data sets. This creates a combined volume data set from the LE and HE volume data sets with optimized image contrast throughout.

  • Patent number: 10335098
    Abstract: In a panoramic imaging apparatus, a panoramic image is displayed on a monitor. The panoramic image is an image in which an overall dentition is in optimal focus, or an image in which a region of interest that is a portion of the image of the overall dentition is in optimal focus. Both images are reconstructed from frame data that has been collected by an initial first scan. Feature points of one or more teeth and a supporting portion that supports the tooth in the dentition in the panoramic image displayed on the monitor are designated. A length based on the positions of the designated feature points is measured in the panoramic image. The degree of loss in alveolar bone that supports the tooth is analyzed based on the measured length. The analysis information is provided to a dentist as check information regarding periodontal disease.

  • Patent number: 10325691
    Abstract: The present invention provides a bright, focused visible light source that is part of a visible light alignment assembly that is coupled to an X-ray generator. The visible light source projects a bright, focused visible light beam from the X-ray generator through a collimator and object or part to be radiographed and to a detector or film, just as a subsequent X-ray beam eventually is. This allows the operator to quickly and easily visually assess the eventual position and coverage or spread of the X-ray beam and align the X-ray generator, collimator, object or part to be radiographed, and/or detector or film, with a minimum of test radiographs.

  • Patent number: 10209372
    Abstract: Methods for discriminating among x-ray beams of distinct energy content. A first volume of scintillation medium converts energy of incident penetrating radiation into scintillation light which is extracted from a scintillation light extraction region by a plurality of optical waveguides that convert the scintillation light to light of a longer wavelength. An x-ray beam initially incident upon the first volume of scintillation medium and traversing the first volume is then incident on a second volume of scintillation medium. The first and second scintillation media may be separated by an absorber or one or more further volumes of scintillation medium, and may also have differential spectral sensitivities. Scintillation light from the first and second scintillation volumes is detected in respective detectors and processed to yield a measure of respective low energy and high-energy components of the incident x-ray beam.
