Abstract
The invention provides for a medical imaging system (). The medical imaging system () comprises a processor (). Execution of machine executable instructions () causes the processor () to: receive magnetic resonance data, wherein the magnetic resonance data comprises B0 field data () of a reference scan for a plurality of voxels and water saturation data () of a WASSR scan for a subset of voxels of the plurality of voxels, the water saturation data () comprising data of a limited number of sample points; determine a local absolute water saturation frequency () for each voxel of the subset using the water saturation data () of the WASSR scan; and reconstruct a field map () comprising a local absolute water saturation frequency for each voxel of the plurality of voxels, wherein the reconstruction comprises determining relative frequency differences between the voxels using the B0 field data () of the reference scan and adding a frequency offset to the relative frequency differences based on the determined local absolute water saturation frequencies () of the subset.
