ABSTRACT:
Systems, methodologies, media, and other embodiments associated with a block-by-block off-resonance frequency estimation method are described. One exemplary method embodiment includes calculating a field map from local B0off resonance frequency estimates. The example method may also include performing water-fat decomposition and signal de-blurring based on the calculated map.
