Ultrasound color flow adaptive scanning techniques

An ultrasound survey frame (SF) is processed in order to determine the portions representing fluid flow. An assembly (20) again rescans only the portions of a subject represented by the portions of the survey frame in which fluid flow was found. Target frames (TF) then are created from the rescanning and are processed in order to provide a color flow image restricted to the portions of the survey frame in which fluid flow is indicated.
