Title:
METHODS FOR THE SIMULTANEOUS DETECTION OF MULTIPLE COMPONENTS OF MOTION IN MOVING FLUIDS
Document Type and Number:
WIPO Patent Application WO/1995/018386
Kind Code:
A1
Abstract:
A motion imaging method (600) 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 (655). Distributions of at least one component of motion are measured responsive to a motion sensitive phase-encoding gradient pulse (660). The method can be used to obtain velocity and acceleration measurements in any of three mutually orthogonal directions.
