Abstract: The present invention relates to an intraoral X-ray system comprising: an intraoral X-ray device equipped with an automatic exposure control (AEC) functionality and connectable to a cloud and a computer, characterized in that at least one intraoral X-ray sensor is connectable to the intraoral X-ray device, and the intraoral X-ray device comprises a functional switch which, in an initial identification process, recognizes the sensor type of the at least one connected intraoral X-ray sensor, and activates an associated mode (M; M′; M″), wherein the intraoral X-ray system comprises one or more of the following modes (M; M′; M″): a mode (M″) for intraoral X-ray sensor side detection of an exposure level, a mode (M′) for intraoral X-ray device, computer or cloud side detection of an exposure level, a mode (M) without detection of an exposure level.

Abstract: The present invention relates to an intraoral X-ray sensor for use with an intraoral X-ray system having an automatic exposure control (AEC) functionality, characterized in that the intraoral X-ray sensor includes an exposure analysis unit, an imaging X-ray detector, and a communication interface, wherein a scout shot or scout video stream received from the imaging X-ray detector is analyzed by the exposure analysis unit in the intraoral X-ray sensor in order to record information on the exposure level of the scout image or video stream and to forward this information by means of the communication interface to a decision unit of the intraoral X-ray system, which is arranged externally to the intraoral X-ray sensor, and adapted for evaluation and decision of further exposures.

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.

Abstract: The invention relates to a method for providing a first and a second digital panoramic layer image optimized for a comparison, wherein the first and second panoramic layer images each have multiple projections detected and stored for them by means of at least one digital detector during an at least partial revolution of a recording unit around an object to be recorded, and the first and second panoramic layer images are each produced from the multiple projections in accordance with a computation code and by forming a panoramic layer. Differences between the first and second panoramic layer images are minimized by altering at least one parameter of the computation code for fresh production of the first and/or second panoramic layer image. In addition, the invention relates to a corresponding apparatus.
