ABSTRACT:
The nuclei in a volume are imaged using one or more time-varying gradient fields. The resultant signals are heterodyned using a signal having a related time-varying component. Equivalently, the spectrum of the resultant signal is convolved with the spectrum of the heterodyne Signal. Following integration, depending on the amplitude of the time-varying component of the heterodyne signal, any point in the volume can be studied from the same received signal.
