SHEAR WAVE VISCOELASTICITY IMAGING USING LOCAL SYSTEM IDENTIFICATION

摘要

The invention relates to a system and method of estimating the viscoelasticity of a material. The method comprises: -receiving a plurality of time-amplitude curves measured at a plurality of space points, wherein said time-amplitude curves reflect time evolutions of a propagating mechanical wave; -estimating the viscoelasticity of a material between any set of space points using the time-amplitude curves measured at those space points.
