Patent ID: 7466128

Claim:
A method of obtaining a localized nuclear magnetic resonance signal from a sample in a static magnetic field using an array of two or more magnetic field transmitting coils, and an array of two or more magnetic field receiving coils, comprising: a) generating a single alternating current excitation pulse on one or more transmitting coils, each of said transmitting coils providing a spatially distinct inhomogeneous field; b) acquiring NMR signals on two or more magnetic field receiving coils; c) applying a plurality of excitation pulses to each transmitting coil or combination of transmitting coils, wherein each excitation pulse has a unique pulse moment defined as the product of the pulse amplitude and pulse length, and wherein the nth pulse moment PM(n) is not equal to (2n−1)*PM(1); and d) constructing a localized nuclear magnetic resonance signal as a linear combination of NMR signals obtained using two or more transmitting coils or combinations of transmitting coils, two or more receiving coils, and two or more pulse moments for each transmitting coil.
