Abstract: A method for magnetic resonance imaging, the method comprising: provisioning a distortion correction function for an extended field of view; provisioning an optimized position along the slice selection direction, wherein the static magnetic field has a high level of homogeneity within the slice at the optimized position in a region in the periphery of the field of view; provisioning an optimized readout gradient, wherein a strength and polarity of the optimized readout gradient are selected so that distortions in the magnetic resonance image caused by inhomogeneities in the static magnetic field and distortions caused by non-linearities in the readout gradient field are superimposed within the region; acquiring the magnetic resonance image at the optimized position along the slice selection direction with the optimized readout gradient; and performing distortion correction on the acquired magnetic resonance image using the distortion correction function.

Abstract: Calculation of shim settings for magnetic resonance imaging includes defining an examination volume for the magnetic resonance imaging in a body of the examination object, determining a local shim volume, which includes a subregion of the examination volume, calculating shim settings, wherein a tissue, which is present in the local shim volume, of the body of the examination object is incorporated into the calculation of the shim settings, and acquiring magnetic resonance raw data of the examination volume by operation of a magnetic resonance scanner, using the calculated shim settings.
