A mechanical pulse is generated at the skin surface, which is propagated through the liver. The velocity of the wave is measured by ultrasound.
The velocity is directly correlated to the stiffness of the liver, which in turn reflects the degree of fibrosis. - the stiffer the liver is the greater the degree of fibrosis.
