Classification: CPC G  A | IPC A  G

Claim 19:
20. A method of training a model for use in medical image processing, the model being constrained by a system of equations representative of a physical model describing underlying physical properties and configured to receive measured 2D physical quantity data, wherein the 2D physical quantity data was obtained from medical imaging measurements, and comprises observations of one or more vector- or tensor-valued fields as projected from one or more 2D acquisition planes, and determine 3D physical quantity data from the 2D physical quantity data, the method comprising:
predicting a 3D data field using the model, from measured 2D physical quantity data;
deriving a 2D projection of the 3D data field;
generating a loss function representative of differences between the derived 2D projection and the measured 2D physical quantity data; and
training the model based on data by minimizing the loss function.
