    Abstract: The present invention relates to a method for automatically generating a projection panoramic view (RPV) from a dental DVT volume of a patient, comprising the steps of; (S1) localizing dental relevant anatomical structures in the DVT volume by using a machine learning method; (S2) automatically placing a guide curve by optimizing it based on the position of the localized dental relevant anatomical structures; (S3) defining a projection region of the reprojection panoramic view using the placed guide curve without manual steps in the DVT volume so that the localized dental relevant anatomical structures are encompassed; (S4) creating the reprojection panoramic view by reprojecting the DVT volume in the defined projection region.

    Abstract: Reconstructing a panoramic image of a patient's dental regions, including: providing at least one initial panoramic image reconstructed by using a plurality of projectional images of the patient and an initial layer including the mapping points corresponding to the patient's dental regions, to be sharply depicted in the initial panoramic image further including: detecting one or more clinically relevant patient-specific pre-selected anatomical structures in the initial panoramic; computing, using the anatomical data and the initial panoramic image, a new layer which includes the clinically relevant patient-specific pre-selected anatomical structure to provide a sharper depiction of the clinically relevant patient-specific pre-selected anatomical structures in a new panoramic image to be reconstructed compared to the depiction of the clinically relevant patient-specific pre-selected anatomical structure in the initial panoramic image; and reconstructing the new panoramic image using the plurality of projectional images of the patient and the computed new layer.

    Abstract: An extraoral dental X-ray apparatus for imaging of a patient in the dental region including: a radiator array having at least two individual radiators each for emitting X-rays, and offset at least along a predetermined direction (z); and an X-ray detector for at least partially detecting the X-rays emitted by the individual radiators, the radiator array and the X-ray detector being rotatably arranged about an axis parallel to said predetermined direction, further including a control device for separately controlling the individual radiators, the control device being configured such that the emitted X-rays of the at least two individual radiators differ in intensity and/or spectral distribution of the X-rays to effect an intensity and/or spectral distribution which can be varied along the predetermined direction. The control device can adaptively adapt the intensity and/or spectral distribution to the anatomy of the patient.

    Abstract: A method and system for dynamically providing visual feedback about a quality of data collected during intra-oral scanning Images or light patterns are projected onto an object such as teeth for 3D measurement and for relaying feedback about a quality of the 3D measurement to a user. In this way unsuccessful registrations surface areas of the teeth that have not been acquired yet may be corrected by informing the user to repeat scans at corresponding locations in the intra-oral cavity.

    Abstract: A method for geometric calibration of a DVT imaging in the dental field, including: (S1) reconstruction of a first volume from a sinogram with an initial projection geometry; (S2) detection of metal areas in the sinogram; (S3) correction of the metal areas in the sinogram; (S4) reconstruction of a second volume from the corrected sinogram from step (S3) with the initial or a varied projection geometry; (S5) geometrically calibrating by varying the projection geometry and evaluating by a similarity measure between a simulated sinogram of the reconstructed second volume and the sinogram or the corrected sinogram.
