Abstract: The invention relates to a device and a method for generating a panoramic layer image (1, 2) of an object (3) to be imaged, by employing a 2D panoramic X-ray device, wherein the object is imaged by projecting X-rays (6) generated by an X-ray source (7) through the object (3) in a projection direction (8) and recording said X-rays (6) with an X-ray detector (9), wherein several 2D X-ray projection images are continuously recorded from various imaging directions while the X-ray source (7) and the X-ray detector (9) move around the object (3), wherein at least one panoramic layer image (1, 2) is calculated from the recorded 2D X-ray projection images by means of a reconstruction method. The panoramic layer image (2) is calculated by selecting and employing at least one partial area (50, 52, 55, 57, 65) from at least two 2D X-ray projection images (51) in relation to an active sensor area (73).

Abstract: The present invention relates to an apparatus (20) for real-time visualizing a movement of a lower jaw (12) versus an upper jaw (14) in a craniomaxillofacial area (16) of a patient (18) in dental diagnostics, comprising: an input interface (32) for receiving a two-dimensional image signal (26) of the craniomaxillofacial area of the patient from a camera (40) and a three-dimensional jaw model (28) of the craniomaxillofacial area of the patient being precalculated based on volume data; a registration unit (34) for registering the three-dimensional jaw model with the two-dimensional image signal in a first jaw position of the lower jaw versus the upper jaw and in a second jaw position of the lower jaw versus the upper jaw; an imaging unit (36) for generating a two-dimensional depth-view (30) of the craniomaxillofacial area from the three-dimensional jaw model based on the conducted registrations and the two-dimensional image signal, said two-dimensional depth-view including a structure underlying an image area of the two-dimensional image signal; and an output interface (38) for outputting the two-dimensional depth-view. The present invention further relates to a system (10) and method for real-time visualizing a movement of a lower jaw (12) versus an upper jaw (14) in a craniomaxillofacial area (16) of a patient (18) in dental diagnostics.

Abstract: The invention relates to a dental x-ray imaging system for producing intraoral x-ray images, in particular of dental patient tissue, with the aid of an intraoral x-ray sensor, which can be placed in the oral cavity in the beam path of an x-ray emitter positioned outside the oral cavity, wherein the x-ray imaging system is configured to record two or more temporally sequential individual x-ray images and to create an overall x-ray image from said individual images in such a way that the results of the exposures of the x-ray images are combined and a motion occurring between and/or during the sequential individual x-ray images is compensated.
