An ultrasonic diagnostic imaging apparatus and method are provided for segmenting signals from nonlinear targets such as microbubble contrast agents. Received echo signals are separated into their constituent linear and nonlinear components by a Doppler filter using pulse inversion separation. A threshold level is derived from an estimate made of the contributions to the echo signal from linear scattering and noise. Echo signals which exceed the threshold level are segmented as nonlinear (microbubble-originating) signals and displayed as such, whereas signals not exceeding the threshold are suppressed in the image display.
