nuclear magnetic resonance velocimetry multiple-modulation multiple-echo velocimetry https://orcid.org/0000-0001-5985-7429 A method for determining the velocity of fluids by encoding it into an NMR signal. The NMR signal is produced using multiple spin echoes from several radio frequency pulses in the presence of a constant magnetic field gradient. 2009-06-30T09:02:55Z CHMO:0002051 MMMEV multiple modulation multiple echo velocimetry
