Abstract: A dental coil comprises a first element and a second element. The first element is composed of a dimensionally stable material and has a recess that is configured to receive at least one of a mouth region or a nose region of a patient when the dental coil is positioned on the jaw region of the patient during use. The second element has a flexible element that is configured to allow the flexible element to take the shape of the jaw region of the patient. The first element and the second element have an antenna configured to receive high-frequency signals in a frequency and power range of a magnetic resonance measurement.

Abstract: Disclosed is a scanning device for magnetic resonance imaging for medical diagnostics, more particularly for dental-medical diagnostics or ENT diagnostics, having a main magnet for generating a static main magnetic field having a homogeneous region, and having at least one transmitting and/or receiving coil for emitting and/or receiving a radio-frequency magnetic field. Provision is made, in particular, for the main magnet to be formed by two poles of magnetically opposite polarities at the end side, such that the static main magnetic field generated by the two poles at the end sides thereof, including the homogeneous region, projects beyond the end sides of the poles.

Abstract: The present invention relates to a method for dental imaging. The imaging method involves providing an image data record relating to at least one maxillofacial image region, and creating a representation of the at least one maxillofacial image region from the image data record, in such a way that the representation includes information relating to the quality of the image data record on which the representation is based.
