ABSTRACT:
A motion imaging method uses magnetic resonance to detect velocity, and an acceleration distribution within moving materials in a subject. Velocity encoding is performed by computing differences of data obtained with modulated motion-encoding magnetic field gradient pulses. Distributions of acceleration are measured responsive to a motion sensitive phase-encoding gradient pulse.
