1. A method of digitally receiving nuclear magnetic resonance (NMR) signals emanating from an object undergoing NMR phenomena during a magnetic resonance imaging (MRI) experiment, said method comprising the following steps:

  • (a) establishing and maintaining, throughout said experiment, a fixed phase relationship between periodic sample timing and said NMR phenomenon;

    (b) digitally sampling NMR signals emanated by said object at said sample timing to provide a sequence of discrete digital samples; and

    (c) generating a phase index throughout said MRI experiment based on said sample timing, said phase index indicating a phase relationship between each of said discrete digital samples and a reference phase.
