Abstract
Methods and systems are provided for predicting Bfield maps from magnetic resonance calibration images using deep neural networks. In an exemplary embodiment a method for magnetic resonance imaging comprises, acquiring a magnetic resonance (MR) calibration image of an anatomical region, mapping the MR calibration image to a transmit field map (Bfield map) with a trained deep neural network, acquiring a diagnostic MR image of the anatomical region, and correcting inhomogeneities of a transmit field in the diagnostic MR image with the Bfield map. Further, methods and systems are provided for collecting and processing training data, as well as utilizing the training data to train a deep learning network to predict Bfield maps from MR calibration images.
