Abstract
Nuclear magnetic resonance (NMR) methods are invented which allow for quantification of sequence-induced B.sub.0 oscillation in magnetic resonance imaging (MRI). The techniques can be used to study any system malfunction which induces sequence-synchronized phase oscillation of the MR signals. When the oscillation is spatially uniform, methods are also developed to correct the acquired NMR data for minimizing the effects of the oscillation.
