5 Publications

1. S. Catheline, F. Wu, M. Fink, A solution to diffraction biases in sonoelasticity: The acoustic impulse technique. J. Acoust. Soc. A., 105 (5), 2941, 1999.

Applied Physics. This paper describes for the first time transient elastography. This technique is used in the Fibroscan®, a commercial device made by Echosens for hepatic deseases diagnostic.

2. Catheline, Gennisson, Tanter, Fink, Observation of Shock Transverse Waves in Elastic Media. Phys. Rev. Lett., 91, 43011, 2003.

Academic Physics. 56 years after the observation of a non linear acoustic wave, this paper describes the experimental observation of a non linear transverse wave. It suggests the existence of a relation ship between linear and non linear elastic coefficients, not described at that time by standard theory of elasticity.

3. Ing, Quieffin, Catheline, Fink, In solid localization of finger impacts using acoustic time-reversal process. Appl. Phys. Lett., 87, 2040104, 2005.

Applied Physics. This paper is at the origin of the first commercial application of time reversal in the field of acoustic interactivity. It is now part of the Sensitive Object® technology.

4. S. Catheline, N. Benech, X. Brum, C. Negreira, Time reversal of elastic waves in soft solids. Phys. Rev. Lett., 100, 064301, 2008.

Academic Physics. Transient elastography allows to observe time reversal of elastic waves inside a soft solid. The Rayleigh criteria for solid imaging is direction dependant. This experiment opens up the way to time reversal tomography of soft tissues.

5. T. Gallot, S. Catheline, P. Roux, J. Brum, N. Benech, C. Negreira,Passive elastography: Shear wave tomograpjhy from physiological noise correlation in soft tissues. IEEE Transactions on UFFC, 58(6), 2011.

Applied Physics. In this paper, an elastography experiment is conducted in vivo in the liver. The novelty is that no shear wave sources are used for the tomography reconstruction. Natural vibrations created by muscles activities (heart) are used in this first passive elastography imaging.
