Abstract: Disclosed is a method for operating a dental diagnostic image generation system of at least two modalities for generating three-dimensional image data by means of X-rays and at least one further beam of a different modality, wherein at least two three-dimensional image data of different modalities are generated and the at least two three-dimensional image data are merged by means of a multimodal registration, it is in particular provided that the image data generation of the at least two three-dimensional image data at an object to be imaged is carried out with markers which overlap during the at least two irradiations of different modalities, that the image data generation of at least one modality is carried out with a capture area limited in accordance with the markers, and that the at least two three-dimensional image data is spatially associated by means of multimodal registration on the basis of the markers captured in the three-dimensional image data.

Abstract: In a method for image enhancement of image data of a dental image generation system, comprising a first image generating unit (205, 210) for producing two-dimensional image data and a second image generating unit (250, 255) for producing three-dimensional image data, wherein for an object to be examined (220, 222) the image generation system provides both two-dimensional image data and three-dimensional image data, it is in particular provided that the two-dimensional image data and the three-dimensional image data are merged in such a way that the image quality and/or the information content of the two-dimensional image data or of the three-dimensional image data is improved.

Abstract: Disclosed herein is an MRI machine for measuring at least a portion of a head of a patient, having at least one primary magnetic field unit and at least one patient opening. The MRI machine has a patient seat, where the patient seat has adjusting means, which are driven by at least one drive means controlled by a control unit to move the patient seat into the patient opening along a travel curve as far as an imaging position, in which the head of the patient is arranged at least partially in an imaging area of the MRI machine, wherein an adjustable element is attached to the patient seat relative to the patient seat and wherein, by means of a detector apparatus, the position of the adjustable element relative to the primary magnetic field unit and/or relative to the patient seat is automatically determined on the MRI machine.

Abstract: Disclosed herein is a method for capturing a dental object with an object volume, in particular, at least one part of a maxilla and/or a mandible, with the sue of an MRT apparatus. A plurality of MRT segment images, which depict the defined segmented volume regions are acquired by an MRT apparatus within a measurement volume of the MRT apparatus. The segmented volume regions overlap no more than partially. In this case a target surface is defined or has already been defined. Then a two dimensional composite image, which corresponds to a two dimensional aggregate image through the target surface within the object volume of the dental object, is generated computer-aided from the individual MRT segment images.

Abstract: Disclosed herein is a method for acquiring a dental object of a patient with an object volume, in particular at least a part of a skull, an upper jaw and/or a lower jaw. To do so, a plurality of segment volume ranges are defined in the object volume, where the segment volume ranges overlap at most partially and directions of the segment volume ranges are not parallel to one another. The image data of the segment volume ranges is recorded by an MRI machine within a measuring volume of the MRI machine. A two-dimensional composite image is generated from the image data of the individual segment volume ranges by projecting the image data onto a target plane. The target plane is disposed parallel to a defined midsagittal plane of the skull or corresponds to the midsagittal plane, where a first segment volume range at least partially includes the midsagittal plane of the skull.

Abstract: Disclosed is a method for calibrating at least one 2D X-ray image of an object to be imaged, which is recorded by an X-ray device in that X-rays produced by an X-ray source radiate through the object and are recorded by an X-ray detector. An already existing 3D model of a structure of the object is compared to the 2D X-ray image, wherein an actual image positional relationship of the X-ray source and the X-ray detector relative to the object, and/or relative to one another, is determined for the 2D X-ray image.
