An ultrasound imaging method and system. The method comprises: for each of a plurality of steer angles, including a reference steer angle, transmitting acoustic energy to a target region at the particular steer angle, receiving acoustic reflections, and converting the acoustic reflections to an image, with the image being associated with the particular steer angle； computing motion information based on the image associated with the reference steer angle； and generating a compounded ultrasound image based on the image associated with each of the plurality of steer angles and based on the motion information.
