Claim 14:
15. A magnetic resonance scanner comprising:
a gradient coil arrangement configured to generate gradient fields to be used during a magnetic resonance 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 in the gradient fields, the controller being configured to:
ascertain 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;
control a user interface to display the original field of view to be set 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;
determine a second set of field-of-view parameters to be used for the MR scan based on the exclusion information; and
control the MR scanner to perform the magnetic resonance scan using the second set of field-of-view parameters.
