METHOD FOR ANALYSING A MEDIUM ALLOWING THE EFFECTS OF ARTIFACTS DUE TO STATIC DEFORMATION IN THE MEDIUM TO BE REDUCED

Abstract

The present invention relates to a method for analysing a region of interest of a viscoelastic medium, the method including a step (200) of acquiring signals representative of the movement of at least one shear-propagation component and of a static-deformation component, and a processing step (300) for determining at least one property of the medium, the processing step comprising the following sub-steps:  determining images of the region of interest;  estimating images of movement by comparing images of the region of interest;  filtering the images of movement to attenuate the static-deformation component;  determining a property of the medium from the filtered images of movement.
