  • Patent number: 9176372
    Abstract: The invention relates to an X-ray device comprising an x-ray sensitive camera for creating tomograms, especially panoramic tomograms. Means for creating 3D shots of a partial volume of the mandibular arch are also provided, said 3D shots being created especially by a second image receiver for creating a 2D shot and means for taking a plurality of 2D shots from different directions and creating a 3D shot therefrom, preferably according to conebeam technology with the associated reconstruction algorithms. The x-ray sensitive camera comprises a first x-ray sensitive image receiver for creating a tomogram, and a second x-ray sensitive image receiver for creating plane shots.
