Abstract:
Disclosed is a method and device for detecting a viscoelastic parameter of a viscoelastic medium. The method comprises: applying a mechanical vibration at a single predetermined frequency to the viscoelastic medium to generate a shear wave in the viscoelastic medium ( 101 ); emitting ultrasonic waves to the viscoelastic medium, and receiving ultrasonic echo signals ( 102 ); acquiring maximum displacement data of the shear wave at various depths according to the ultrasonic echo signals ( 103 ), each of the maximum displacement data representing a maximum oscillation amplitude of the shear wave when the shear wave propagates to different depths in the viscoelastic medium; fitting each of the maximum displacement data to obtain a maximum displacement attenuation curve ( 104 ); and determining the viscoelastic parameter of the viscoelastic medium according to the maximum displacement attenuation curve ( 105 ). The method and device can provide a more accurate measurement result of tissue fibrosis.

Claim (Index 2):
The method according to  claim 1 , wherein before the acquiring maximum displacement data of the shear wave at various depths according to the ultrasonic echo signals, the method further comprises:\n performing at least one of the following signal processings on the ultrasonic echo signals: time domain cross correlation, spectral cross correlation, square error sum, speckle tracking, scale invariant feature point tracking, dynamic programming, zero cross tracking, and peak search.
