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.
A method for acquiring, with a magnetic resonance tomograph, a magnetic resonance image with an extended field of view that is extended in at least one direction, wherein the magnetic resonance tomograph is configured to, in the extended field of view, produce a static magnetic field and magnetic gradient fields extending in a slice selection direction, a readout direction, and at least one phase encoding direction, wherein during acquisition, an MR signal is acquired from signal-generating spins in the extended field of view, and wherein the method comprises:
