Spectral and nonlinear amplitude dependent characteristics of ultrasonic wave propagation may be used for medical diagnostics of relatively small skin elasticity changes. The noninvasive method has been proposed, based on guided wave propagation along the surface of forearm radial part. A special procedure of the precise signal arrival detection has been designed, and used for wave propagation velocity evaluation. Rapid noninvasive ultrasonic evaluation of human skin in-vivo is useful in many dermatology applications such as surgery, medical treatment and also in cosmetics.
