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: A method for generating a panoramic layer image of an object to be imaged, by employing a 2D panoramic X-ray device, the object being imaged by projecting X-rays generated by an X-ray source through the object in a projection direction and recording the X-rays with an X-ray detector. Several 2D X-ray projection images are continuously recorded from various imaging directions while the X-ray source and the X-ray detector move around the object. At least one panoramic layer image is calculated from the recorded 2D X-ray projection images using a reconstruction method. The panoramic layer image is calculated by selecting and employing at least one partial area from at least two 2D X-ray projection images in relation to an active sensor area.

Abstract: In a method for image enhancement of image data of a dental image generation system, comprising a first image generating unit (205, 210) for producing two-dimensional image data and a second image generating unit (250, 255) for producing three-dimensional image data, wherein for an object to be examined (220, 222) the image generation system provides both two-dimensional image data and three-dimensional image data, it is in particular provided that the two-dimensional image data and the three-dimensional image data are merged in such a way that the image quality and/or the information content of the two-dimensional image data or of the three-dimensional image data is improved.

Abstract: An apparatus for real-time visualizing a movement of a lower jaw versus an upper jaw including: an input interface for receiving a two-dimensional image signal of the craniomaxillofacial area of the patient from a camera and a three-dimensional jaw model of the craniomaxillofacial area of the patient being precalculated based on volume data; a registration unit 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 for generating a two-dimensional depth-view of the craniomaxillofacial area from the three-dimensional jaw model based on the conducted registrations and the two-dimensional image signal, the two-dimensional depth-view including a structure underlying an image area of the two-dimensional image signal; and an output interface for outputting the two-dimensional depth-view.

Abstract: A measurement and data communication device for use in or with an intraoral dental radiology system comprising: an x-ray data management unit having a first communication means for retrieving at least x-ray exposure data, and a processing means for processing at least the retrieved data; an intraoral x-ray generation unit having an x-ray source for exposing at least part of a patient jaw with x-rays; and an intraoral x-ray acquisition unit having a first x-ray sensor for acquiring x-ray image data of at least part of the patient jaw. The device further includes: a measurement unit for measuring features related to the x-rays used for exposing at least part of the patient, the measurement unit being arranged between the x-ray source and the patient; and a second communication means for transmitting the x-ray exposure data which includes the measured features to the x-ray data management unit.
