Claim 0:
1. A computer-implemented method for setting a field of view for a magnetic resonance (MR) scan of a patient with a MR scanner including a gradient coil arrangement configured to generate gradient fields to be used during the MR scan for spatial encoding and a controller configured to perform distortion correction based on a distortion map of acquired magnetic resonance data sets at least for distortions caused by imperfections of the gradient fields, the method comprising:
ascertaining, by the controller, exclusion information describing an unmapped region of an original field of view based on the distortion map for at least one first set of field-of-view parameters describing a rectangular or cuboidal original field of view, the unmapped region resulting from the distortion;
displaying the original field of view to be set in a user interface together with an anatomy of the patient to be scanned, wherein the unmapped region is displayed based on the exclusion information and/or a limitation of the field of view display for exclusion of the unmapped region is adjusted based the exclusion information;
determining, by the controller, a second set of field-of-view parameters to be used for the MR scan based on the exclusion information; and
controlling, by the controller, the MR scanner to perform the magnetic resonance scan using the second set of field-of-view parameters.
