The present invention provides a shear wave imaging method. The method comprises the following steps: generating a shear wave in a tissue; pre-estimating the shear wave, sending tracking pulses many times at positions of the shear wave at different time points and receiving echo information of the tracking pulses; performing shear wave parameter calculation according to the echo information of the tracking pulses; and displaying a result of the shear wave parameter calculation in the form of an image. According to the shear wave imaging method and system provided in the present invention, a detection position of a shear wave is pre-estimated, so that shear wave detection can be accurately performed in a small range, and therefore detection energy is relatively concentrated and the signal-to-noise ratio of the detection is improved; the number of redundant detections is reduced, the detection process is accelerated, and the load of data processing is reduced. The present invention also provides a shear wave imaging system. |
