  • Patent number: 10695008
    Abstract: The present invention provides an X-ray imaging device including an X-ray emitter and an X-ray detector rotating while facing each other with an imaging subject interposed therebetween, a device controller controlling the X-ray imaging device such that a first X-ray imaging is performed with a first dose in a partial section of a rotation locus of the X-ray emitter and the X-ray detector and a second X-ray imaging is performed with a second dose lower than the first dose in a remaining section, and an image processor producing an X-ray image by receiving first and second X-ray image data of the first and the second X-ray imaging from the X-ray detector.
    Type: Grant

  • Patent number: 10492743
    Abstract: Disclosed are an X-ray imaging apparatus capable of acquiring highly accurate three-dimensional surface data as well as a CT image of teeth and surrounding tissues thereof of a subject without increasing the dose of X-ray and the discomfort for the subject compared to conventional CT imaging, and an X-ray imaging method using the same. The X-ray imaging apparatus includes an X-ray generator; an X-ray sensor disposed to face the X-ray generator, and configured to receive X-rays transmitted through a subject to generate an electric signal, and a subject jig configured to support the subject and to move the subject to be relatively rotated about at least two axes with respect to an X-ray propagation path, wherein a CT image and high-precision three-dimensional surface data are reconstructed and provided by using a plurality of X-ray imaging data acquired through a plurality of scan sequences.
