Title: Innovations of Stéphane Audière in Elastography

Introduction

Stéphane Audière is a notable inventor based in Paris, France. He has made significant contributions to the field of elastography, particularly through his innovative devices and methods. With a total of two patents to his name, Audière's work focuses on improving medical imaging and diagnostics.

Latest Patents

Audière's latest patents include an elastography device and method. The elastography device features a probe with a protruding part designed to be applied against the body of a subject. It incorporates a low-frequency vibrator that moves the protruding part, along with at least one ultrasound emitter and one ultrasound receiver. The electronic unit of the device is capable of controlling its operation in two modes: a guidance mode for proper positioning and a measurement mode for assessing mechanical properties of the probed region. In guidance mode, the vibrator delivers a series of probing pulses, and the electronic unit determines a propagation quality indicator representative of the probed region's ability to transmit these pulses.

Another significant patent is a method and device for measuring an ultrasound parameter of a viscoelastic medium. This system accumulates ultrasound attenuation data to detect diseases or other conditions. During imaging mode, the ultrasound system generates multiple imaging pulses, and the echo signals received are tested against quality metrics. The attenuation data from the echo signals that meet these metrics are then used to compute a tissue characteristic, such as a CAP measurement related to liver fat content.
