Abstract
A shear rate imaging method uses magnetic resonance to detect the distribution of velocities within a subject. Distributions are measured responsive to at least two different field-of-views. Differences of the velocity distribution obtained with one field-of-view and the second field-of-view are computed to give a component of shear rate. The method can be used to obtain velocity measurements in any of three mutually orthogonal directions responsive to field-of-view shifts in as many as three mutually orthogonal directions to give a total of nine shear rate components. Data for each component can be acquired independently or data acquisition can be multiplexed to reduce data acquisition requirements.
