Often complex projection data is used for fast assessment of B0 field inhomogeneities. We here present considerations concerning dephasing effects to be taken into account when dealing with such complex projection data, and present a possible solution for the example of an Echo Planar Imaging sequence, comparing field inhomogeneities detected by projections with values from field maps.
