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.

1-21. (canceled)
An X-ray system having an X-ray-sensitive camera for the creation of tomographic images, which camera includes a first and a second image detector, wherein said first image detector is provided for the creation of a panoramic tomographic image and said second image detector for the creation of a 2D image, and means are provided for the creation of 3D images of a subvolume of the mandibular arch, which means create several 2D images from different directions and compute a 3D image therefrom, and including adjustment means by means of which said camera and/or said image detector and/or said X-ray emitter and/or a primary diaphragm and/or combinations thereof can be adjusted such that said second image detector present in said camera can be moved into the optical path of said X-ray emitter.
An X-ray-sensitive camera, comprising a first X-ray-sensitive image detector for the creation of a tomographic image, a second X-ray-sensitive image detector for the creation of plane images and wherein the two image detectors are disposed in a common casing, and said second image detector is disposed alongside said first image detector and including adjustment means for the purpose of 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.
