    Abstract: The invention relates to an orthodontic diagnostic method wherein at least one initial two-dimensional X-ray image (1) of a first zone (2) of a head (3) is taken. Then at least one three-dimensional X-ray image (4) of a second zone (5) of a dental situation is taken, and the three-dimensional X-ray image (4) is combined with the initial two-dimensional X-ray image (1) using a registration process in order to obtain a full image (8).

    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.

    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).
