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 (); emitting ultrasonic waves to the viscoelastic medium, and receiving ultrasonic echo signals (); acquiring 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; fitting each of the maximum displacement data to obtain a maximum displacement attenuation curve (); and determining the viscoelastic parameter of the viscoelastic medium according to the maximum displacement attenuation curve (). The method and device can provide a more accurate measurement result of tissue fibrosis.
