Correction of distortions due to the pulsed magnetic field gradient-induced shift in B0 field by postprocessing.
Gradient pulses used in most localization techniques induce time-dependent shifts in B0 that strongly distort NMR signals. A postprocessing correction method requiring no additional hardware is proposed. The phase shift produced by the B0 shift is calculated from a reference free induction decay (FID) and used to correct any FID acquired with the same sequence.
