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 9):
A device for detecting a viscoelastic parameter of a viscoelastic medium, comprising:\n a control host and a probe, the probe including a vibrator and an ultrasonic transducer, wherein the vibrator, under the control of the control host, applies a mechanical vibration at a single predetermined frequency to the viscoelastic medium to generate a shear wave in the viscoelastic medium; during propagation of the shear wave in the viscoelastic medium, the ultrasonic transducer, under the control of the control host, emitting single-source ultrasonic waves to the viscoelastic medium and receives ultrasonic echo signals; and the control host comprises: a first acquiring module that is configured to acquire maximum displacement data of the shear wave at various depths according to the ultrasonic echo signals, 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; a computing module that is configured to fit the maximum displacement data to obtain a maximum displacement attenuation curve; and a first determining module that is configured to determine the viscoelastic parameter of the viscoelastic medium according to the maximum displacement attenuation curve.
