A motion imaging method uses magnetic resonance to detect the two or more components of motion such as velocity, acceleration or jerk within a subject. One component of motion is detected by computing differences of data obtained with modulated motion-encoding magnetic field gradient pulses. Distributions of at least one component of motion are measured responsive to a motion sensitive phase-encoding gradient pulse. The method can be used to obtain velocity and acceleration measurements in any of three mutually orthogonal directions.
