摘要： The invention relates to a system and a method for determining the color of teeth or tooth surfaces, wherein the system comprises a 2D or 3D camera and an attachment on said camera, which sets a geometry of a captured image in such a way that, compared to capturing an image without the attachment, the distance, spatial angle and orientation of tooth surfaces relative to the camera are restricted. The attachment according to the invention can in particular be fitted to the camera in a simple manner.

摘要： The present teachings relate to a method for assisting an intraoral scan including providing an intraoral image of a patient, and providing an extraoral image; the extraoral image being representative of the position of an extraoral scanner part. The teaches further include generating, using the intraoral image and the extraoral image, a mapping function correlating the position of the extraoral scanner part with the position of the intraoral scanner part; and computing, using the mapping function, a desired extraoral position of the extraoral scanner part; the desired extraoral position corresponding to a preferable intraoral position of the intraoral scanner part. The present teachings also relate to a system, a device, a use, data, and a storage medium.

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： 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： The present invention proposes a method for producing a 2D panoramic image of an oral cavity comprising the steps: A) provision of a plurality of projection images acquired during an at least partial revolution of a recording unit comprising a radiation source and an electronic image sensor about the oral cavity in a given position; B) calculation of an image including at least one anatomical feature from the plurality of projection images using a calculation rule with reconstruction parameters; C) provision of a model of the at least one anatomical feature, which describes the at least one anatomical feature in a target position in an image; D) identification of the at least one anatomical feature in the calculated image; E) determination of a deviation between an actual position of the at least one identified anatomical feature in the calculated image and the target position of the at least one anatomical feature in the model by applying a metric; F) variation of at least one of the reconstruction parameters and recalculation of at least one part of the image that shows the at least one anatomical feature using the calculation rule and the at least partially varied reconstruction parameters or variation of a pixel transformation and application of the pixel transformation to at least one part of the calculated image that shows the at least one anatomical feature, so that at least this part of the image is recalculated; G) derivation of the 2D panoramic image from the recalculated image; and H) outputting the 2D panoramic image.

摘要： A method for generating a panoramic image with reduced overlapping of neighboring teeth, including: acquiring 2D x-ray images respectively at a different radiographic directions by a rotating an x-ray source and an x-ray detector around the jaw of a patient. It includes a step of identifying one or more regions each including at least one pair of overlapping neighboring teeth in the 2D x-ray images and/or in temporary panoramic images reconstructed from the 2D x-ray images for which an optimal radiographic directions are determined, among the corresponding radiographic directions, which reduces the overlap in the panoramic image to be reconstructed. It includes determining one or more optimal radiographic directions respectively among the corresponding radiographic directions of the 2D x-ray images for which one or more regions each including at least one pair of overlapping neighboring teeth has been identified, to reduce the overlaps in the panoramic image to be reconstructed.
