1. An ultrasound imaging system which produces extrapolated images comprising:
a transducer array probe; and
one or more processors in communication with the transducer array probe, the processor configured to:
separate signals received by the transducer array probe into two imaging signal paths of different imaging characteristics;
beamform signals, from each imaging signal path, for images of different imaging characteristics;
produce ultrasound images of different imaging characteristics;
predict an extrapolated image by extrapolation of the ultrasound images;
remove artifacts resulting from extrapolation which are not speckle from the extrapolated image;
perform smoothing of the speckle of the extrapolated image; and
display a final image predicted by the extrapolation.
