ABSTRACT:
A signal function S(t.sub.1, t.sub.2) is obtained from a plurality of coherence transfer pathways in a single acquisition by preparing a molecular system in a coherent non-equilibrium state, and alternately and sequentially detecting signals at individual sampling points, in t.sub.2, from the plurality of coherence transfer pathways by using gradient refocusing of a new pathway after siganl detection at a sampling point in another pathway. The gradient encoding and refocusing of coherence pathways can use inhomogeneous rf-pulses (B.sub.1 gradients) or B.sub.0 field gradients. The coherence transfer pathways can be sequentially selected in an arbitrary order.
