Abstract: An intelligent restoration proposal including using an input resource to segment a 3D jaw model to obtain a segmented missing or unhealthy teeth and omitting the segmented missing or unhealthy teeth from the 3D jaw model to obtain a modified 3D jaw model. The modified 3D jaw model is used as input to a restoration proposal module to propose an output restoration. The restoration proposal module is operated as a machine learning engine. The restoration proposal is trained using a database that includes healthy teeth.

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: Aspects relate to geometric calibration of a DVT imaging, by updating the geometric parameters used in a reconstruction method, in which the updating of the geometric parameters is supported by a first correction method based on machine learning (ML) by using the result of a first correction method as a reference for a second correction method for parameter estimation, and in which the second correction method for parameter estimation involves the measurement data of the DVT imaging, which includes the following steps: (S1) providing the measurement data of the DVT imaging and the geometric parameters; (S2) providing a first volume by applying a reconstruction method to the provided measurement data and the geometric parameters; (S3) providing a corrected volume by applying the first correction method to the first volume; (S4) providing updated geometric parameters by applying the second correction method to the measurement data and the corrected volume.
