Characterization of the Anisotropy and Directional-Dependent Nonlinearity of the Human Skin In-vivo Using Ultrasound

Popis výsledku v původním jazyce

Anisotropy is a property of material describing directional dependence of various phenomena and plays an important role in material characterization. Human skin represents anisotropic bio-polymer with complex mechanical behavior and exhibits highly nonlinear and hysteretic effects. Knowledge of such mechanical properties of the human skin is of great interest in plastic surgery, dermatology, cosmetics, and related fields. This contribution deals with noninvasive in-vivo method for characterization of the human skin anisotropy and nonlinear properties. The method exploits a special flexible multi-directional circular probe with built-in piezoelectric transducers (ultrasonic array) for elastic waves propagation measurements. The anisotropy level of the human skin is evaluated from directional dependence of elastic wave velocity related to complex elastic modules. Spectral characteristics and harmonic series ratios obtained in different directions are used for characterization of directio
