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: A magnetic resonance system may include a magnetic resonance device, an optical imaging device, and a controller. The controller may control the magnetic resonance device to acquire magnetic resonance image data from an object inside an oral cavity of a patient and/or control the optical imaging device to acquire optical data from the object inside the oral cavity of the patient. The controller (e.g., a processor of the controller) may merge the optical data with the magnetic resonance image data.
