Abstract
The invention relates to an x-ray device (50) comprising an x-ray sensitive camera (55) 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 (5) 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 (55) comprises a first x-ray sensitive image receiver (4) for creating a tomogram, and a second x-ray sensitive image receiver (5) for creating plane shots.
Claims2
An X-ray-sensitive camera, comprising a casing, a first X-ray-sensitive image detector for the creation of a tomographic image in said casing, a second X-ray-sensitive image detector for the creation of plane images in said casing, said second image detector being positioned behind said first image detector, with X-ray-sensitive surfaces of said first and second image detectors facing in opposite directions, and including adjustment means for causing, as desired, said first image detector or said second image detector to assume correct alignment relative to an X-ray emitter for the creation of the respective X-ray image.
