A shear wave propagation speed determination method and device. The method comprises: when a shear wave propagates along a tissue region of interest, acquiring motion data of each preset position point in the tissue region of interest (step); determining a value of the motion data of each preset position point (step), wherein the magnitude of the value represents regularity of a propagation waveform of the shear wave; and if the value meets a first preset condition, determining, on the basis of the motion data of each preset position point in the tissue region of interest, a propagation speed of the shear wave at each preset position point in the tissue region of interest (step). The invention improves accuracy in determination of the propagation speed of a shear wave.

A method for simultaneously performing blood flow Doppler imaging and pulse Doppler imaging includes: sequentially transmitting each transmission sequence group including multiple blood flow sequences and a B-mode sequence thereafter; sequentially receiving a first echo signal group reflected by a tissue area of interest in response to the blood flow sequence; sequentially performing beam composition on the first echo signal group corresponding to the blood flow sequence transmitted each time, to obtain a first multi-beam corresponding thereto; sequentially performing wall filtering on the first multi-beam corresponding to the blood flow sequence transmitted each time, to obtain a second multi-beam corresponding thereto, wherein the second multi-beam is a multi-beam representing a blood flow signal in the first multi-beam; and performing a blood-flow-mode imaging process and a blood flow spectrum imaging process based on sequentially obtained second multi-beams.
