Title (EN) LOSS-ANGLE-BASED DETERMINATION OF A MEDIUM VISCOELASTIC PARAMETER IN SUB-HERTZ FREQUENCY RANGE WITH THE USE OF LOCAL CREEP RESPONSE
(FR) DÉTERMINATION BASÉE SUR L'ANGLE DE PERTE D'UN PARAMÈTRE VISCOÉLASTIQUE DE MILIEU DANS UNE GAMME DE FRÉQUENCES DE SOUS-HERTZ À L'AIDE D'UNE RÉPONSE LOCALE AU FLUAGE
Abstract: front page image
(EN)System and method configured to characterize viscoelasticity of a target medium by directly determining phase difference between reai and imaginary parts of the complex shear modulus of the tissue (determined as a result of applying a compression force to the tissue), and without any fitting of data and independent from distribution of strain in tiie tissue caused by the application of compression force.
(FR)L'invention concerne un système et un procédé conçus pour caractériser la viscoélasticité d'un milieu cible en déterminant directement la différence de phase entre des parties réelles et imaginaires du module de cisaillement complexe du tissu (déterminé suite à l'application d'une force de compression sur le tissu), et sans adaptation des données et indépendamment de la répartition de la contrainte dans le tissu provoquée par l'application d'une force de compression.
