Abstract:
1. A device configured to measure the viscoelastic properties of biological tissues using a processing of ultrasound waves reflected by the biological tissues when a shear wave runs across them, the device comprising: memories configured to form lines of data such that each line comprises data relative to the ultrasound waves reflected from a same shot, a calculator configured to determine a relative parameter that is relative to a displacement between the tissues and a transducer emitting the shots, a calculator configured to calculate an intrinsic displacement of a medium from a set of lines forming an acquisition, and a calculator configured to process first ultrasound lines, by using the relative parameter, before or during the formation of second ultrasound lines from a same acquisition, in order to determine the intrinsic displacement of the biological tissues from said first lines.
