SHEAR WAVE VISCOELASTICITY IMAGING USING LOCAL SYSTEM IDENTIFICATION

摘要

Some embodiments relate to a system and method of estimating the viscoelasticity of a material. The system and method includes receiving a plurality of time-amplitude curves measured at a plurality of space points. The time-amplitude curves reflect time evolutions of a propagating mechanical wave. The system and method also include estimating the viscoelasticity of a material between any set of space points using the time-amplitude curves measured at those space points.
