Title (EN) SHEAR WAVE VISCOELASTICITY IMAGING USING LOCAL SYSTEM IDENTIFICATION
(FR) IMAGERIE DE VISCOÉLASTICITÉ D'ONDE DE CISAILLEMENT À L'AIDE D'UNE IDENTIFICATION DE SYSTÈME LOCAL
Abstract:
(EN) 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.
(FR) L'invention concerne un système et un procédé d'estimation de la viscoélasticité d'un matériau. Le procédé consiste : - à recevoir une pluralité de courbes temps-amplitude mesurées au niveau d'une pluralité de points spatiaux, lesdites courbes temps-amplitude reflétant des évolutions temporelles d'une onde mécanique propagée ; - à estimer la viscoélasticité d'un matériau entre n'importe quel ensemble de points spatiaux à l'aide des courbes temps-amplitude mesurées au niveau desdits points spatiaux.
