Abstract
A device configured to measure the viscoelastic properties of biological tissues using a processing of ultrasound waves reflected by these tissues when a shear wave runs across them is presented. The device includes memories for forming lines of data such that each line comprises data relative to the ultrasound waves reflected from the same shot and a calculator for determining a parameter relative to the displacement between the tissues and a transducer emitting the shots, a calculator for calculating an intrinsic displacement of the medium from a set of lines forming an acquisition, and a processor for processing the first ultrasound lines, by using the relative parameter, before or during the formation of second ultrasound lines from this same acquisition, in order to determine the intrinsic displacement of the biological tissues from these first lines.
