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 producing an x-ray image (1) of an object (2) by means of an x-ray device (3). An x-ray source (4) and an x-ray detector (5) are moved about an object (2) during an at least partial circulation (8, 9), and the x-ray beams (10) which are generated by the x-ray source (4) and pass through the object (2) are detected from multiple different directions by means of the x-ray detector (5). In the process, at least one optical camera (13, 14) captures the object (2) during the circulation, wherein an optical image (15, 17) is produced. The optical camera (13, 14) has a rigidly defined position relative to the x-ray source (4) and/or the x-ray detector (5). The optical image (15, 17) is then used to determine a movement trajectory of the object (2) relative to the x-ray source (4) and/or the x-ray detector (5).

Abstract: A method, apparatus, and computer readable medium for removing an unwanted object from an image volume are provided. Volumetric data of an object of study is generated in a radiographic scan. Volumetric data of the unwanted object is obtained. The two sets of volumetric data are registered in a common coordinate system. The unwanted object is removed from the volumetric data of the object of study to create modified volumetric data of the object of study. Data from voxels surrounding the removed unwanted object may be used to populate voxels corresponding to the unwanted object with interpolated data. A plurality of forward projections are performed on the modified volumetric data of the object of study, and a tomogram with the unwanted object removed is constructed.
