Abstract :
Transient elastography (TE) is a parametric technique used to quantify Young´s modulus (E) by estimating the shear wave (SW) velocity (Vs) in an homogeneous medium. TE has been successfully integrated in the Fibroscan® device to assess fibrosis stages in the liver. Considering the last as homogeneous and elastic, fibrosis is correlated to averaged E at 50 Hz low vibration. In this poster, we present a preliminary study using a new development in TE dedicated to 1D high resolution (HR) estimation of E in thin, heterogeneous and viscoelastic medium such as the skin. The HR TE targets to offer a new elastographic tool to characterize viscoelatic parameters of the human dermis in dermatology and cosmetology.
