摘要： The invention relates to a method for producing a panoramic tomographic image (1, 11, 60) of an object (2) to be recorded using a 2D panoramic X-ray device (3), in the course of which X-rays (4) produced by means of an X-ray source (5) irradiate the object (2) and are acquired by means of an X-ray detector (7), wherein, during a movement of the X-ray source (5) and the X-ray detector (7) around the object (2), a number of 2D X-ray projection images (30) are acquired from different acquisition directions (6). A first panoramic tomographic image (1) is calculated from the acquired 2D X-ray projection images (30) using a reconstruction method, wherein the acquired 2D X-ray projection images (30) are modified using a modification method, wherein, from the modified 2D X-ray projection images (40, 50) and using the reconstruction method, a second panoramic tomographic image (11) is calculated with a higher weighting of artifacts (20) relative to anatomical structures (17, 18, 19), wherein a third panoramic tomographic image (60) with significantly reduced artifacts is calculated.

摘要： Disclosed is a device for matching three-dimensional intra-oral scan data, the device comprising a computed tomography (CT) image depth map generation unit, a depth map coordinate difference information determination unit, a depth map correction unit, and an intra-oral scan model recovery unit. The CT image depth map generation unit generates a depth map of a CT frame from a CT image by using information about a single scan frame of the scan data. The depth map coordinate difference information determination unit determines depth map coordinate difference information between the depth map of the CT frame and a depth map of the scan frame. The depth map correction unit corrects the depth map of the scan frame on the basis of the depth map coordinate difference information. The intra-oral scan model recovery unit recovers a three-dimensional intra-oral scan model on the basis of the corrected depth map of the scan frame.

摘要： Techniques are provided for x-ray sensing for intraoral tomography. A methodology implementing the techniques according to an embodiment includes detecting an x-ray pulse based on energy received at one or more pixels of a pixel array. The method also includes integrating the energy received at each of the pixels of the array of pixels, in response to the detection, wherein the energy received at each of the pixels is associated with the x-ray pulse. The method further includes multiplexing readouts of analog signals from the array of pixels into two or more parallel channels. The method further includes simultaneously converting (or otherwise in parallel) the analog signals of each of the channels into digital signals and storing the digital signals in memory as frames of data. The method may further include, for example, transmitting the frames of data from the memory, over a Universal Serial Bus, to an imaging system.

摘要： An intra-oral imaging system includes an imaging device and a control device. The imaging device includes an imager, a controller, and a case in which the imager and the controller are housed. The imager performs imaging detection for detecting radiation in order to acquire an image of an object and monitoring detection for detecting radiation in order to monitor the dose of radiation. The controller transmits an imaging signal and a monitoring signal to the control device, the imaging signal acquired by the imaging detection and the monitoring signal acquired by the monitoring detection. The control device receives the imaging signal and the monitoring signal, and transmits a control command to the controller, the control command generated based on the monitoring signal. The controller controls the imager according to the control command.

摘要： 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.

摘要： Disclosed is surface guided cropping in volume rendering of 3D volumetric data from intervening anatomical structures in the patient's body. A digital 3D representation expressing the topography of a first anatomical structure is used to define a clipping surface or a bounding volume which then is used in the volume rendering to exclude data from an intervening structure when generating a 2D projection of the first anatomical structure.

摘要： A method for visualizing patient dentition acquires a contour image of patient dentition and segments the contour image to identify one or more segmented teeth. At least one deciduous tooth among the one or more segmented teeth is identified. A virtual model of a target dentition arrangement of the patient dentition is generated, wherein the at least one deciduous tooth is replaced by a replacement permanent tooth.
