✦ Synopsis
Gradient pulses used in most localization techniques induce time-dependent shifts in Bo that strongly distort NMR signals. A postprocessing correction method requiring no additional hardware is proposed. The phase shift produced by the Bo shift is calculated from a reference free induction decay (FID) and used to correct any FID acquired with the Same sequence.
