Claim 9:
10. A magnetic resonance (MR) device including at least one main magnet coil for generating a uniform, static magnetic field within an examination volume, a number of gradient coils for generating switched magnetic field gradients in different spatial directions within the examination volume, at least one RF coil for generating RF pulses within the examination volume and/or for receiving MR signals from an object positioned in the examination volume, a control unit for controlling a temporal succession of RF pulses and switched magnetic field gradients, and a reconstruction unit for reconstructing a MR image from the received MR signals, wherein the MR device is arranged to perform a method comprising:
subjecting the object to an imaging sequence comprising at least one RF excitation pulse and modulated magnetic field gradients,
acquiring MR signals along at least one non-Cartesian k-space trajectory,
reconstructing an MR image from the acquired MR signals,
deblurring the reconstructed MR image based on a B0 map; and
detecting one or more mal-sampling artefacts caused by inhomogeneity induced insufficient k-space sampling in the deblurred MR image using a deep learning network.
