Abstract
A method of power Doppler imaging may include receiving a plurality of temporally sequential frames of wall-filtered power Doppler signals, wherein the plurality of temporally sequential frames includes at least one previously adjusted output frame. The method may further include adjusting at least one of the plurality of temporally sequential frames to produce an adjusted output frame and generating a power Doppler image based, at least in part, on the adjusted output frame. The adjusting may involve filtering the plurality of temporally sequential frames to suppress the high spatial frequency and high temporal frequency content to produce the adjusted output frame.
