An echo processor (117) for an ultrasound imaging device (102) includes a frame processor (118) that aligns a plurality (N) of sequentially received frames of echoes based on a set of motion displacement fields for the plurality of frames and combines the aligned plurality of sequentially received frames, thereby forming a compounded frame. A method includes obtaining a set of frames of echoes acquired at different times, determining a motion displacement field based on at least two of the frames of the set, motion-compensating all of the frames of the set based on the displacement field and previously determined displacement fields, and generating a compounded frame based on the motion-compensated frames.
