Claim One:
1. A method of magnetic resonance (MR) imaging of at least a portion of a body of a patient positioned in an examination volume of a MR device the method comprising: with a controller, controlling currents in RF coils and magnetic field gradient coils of the MR device in order to implement a multi-point Dixon imaging technique that generates first MR image data at a first image resolution; with one or more computer processors: reconstructing the first MR image data in order to generate a B0 field map, a water image, and a fat image at the first resolution, segmenting the water and fat images in order to identify a water region and a fat region, determining a B 0 homogeneity in the identified water region and a B 0 homogeneity in the identified fat region, determining shim settings utilized by shim coils of the MR device where the determined shim settings achieve at least one of: maximizing B 0 homogeneity in the identified water region, maximizing B 0 in the identified fat region, and improving B 0 homogeneity in both the identified water region and the identified fat region; with the controller, implementing a diagnostic MR imaging sequence including: controlling currents in the shim coils according to the determined shim settings, and controlling currents in the RF coils and the magnetic field gradient coils in order to generate diagnostic MR image data at a second image resolution which is higher than the first image resolution; and with the one or more computer processors, reconstructing the generated diagnostic MR image data into a diagnostic MR image with the second image resolution.
