Abstract
The results of application of the ultrasonic (US) Doppler method for measuring the elasticity of skeletal muscles lying at a small depth (2–4 cm) from the skin surface are presented. The technique is based on calculating the speed of shear waves excited by a vibrator on the skin’s surface at frequencies of 150–250 Hz. The distribution of shear displacements in an elastic phantom, calculated by the finite element method, was compared with the results of measurements using a miniature accelerometer. The shear modulus of the elastic phantom, measured using the proposed technique, corresponds to values obtained from static measurements.
