Off resonance artifact and correction demonstration. Note that in the normal vs. reversed gradient polarity the fiducial markers along the green line shift along the frequency-encoded direction (right-left). The magnified insets emphasize this effect. These images are reconstructed with the vendor standard 5th order gradient non-linearity correction method in order to demonstrate the B0 off resonance effect, but the correction itself is done on non-GNL compensated data.
