Ultrasonic Time Reversal Technique Used to In-Vivo Investigation of Human Skin Under Loading
Original language description
Mechanical behavior of human skin is of great interest in dermatology, plastic surgery and cosmetics. Small changes in viscoelastic properties of the skin are very sensitively reflecting some skin and also internal diseases. This contribution deals withultrasonic noninvasive investigation of viscoelastic properties of the human skin under stepwise tensile loading in-vivo. A small skin-loading device with built-in ultrasonic transmitting and receiving probes is used to observe elastic wave propagation changes during the complex short time step loading and relaxation history. Chirp coded ultrasonic signals of variable amplitude in the frequency range (0.1 ? 1) MHz are transmitted along the forearm of several all-aged persons. Linear ultrasonic parameters like velocity and attenuation are evaluated direct propagating waves, and Time Reversal (TR) procedure is used to reveal amplitude dependent spectral changes and nonlinear effects during the wave propagation at different loading and rel
