ABSTRACT:
In an NMR system a method for measuring the motion of spins moving in an unknown direction includes four separate measurement cycles. The first cycle establishes a reference phase and each of the subsequent three measurement cycles includes motion encoding field gradients for measuring motion along respective pairs of Cartesian coordinates. All four measurements are combined to calculate each of the motion components along x, y and z coordinates.
