Claim 11:
12. An ultrasound imaging system which produces extrapolated images comprising:
a transducer array probe;
a signal separator, adapted to separate signals received by the transducer array probe into two imaging signal paths of different imaging characteristics;
a beamformer coupled to the signal separator in each imaging signal path which is adapted to beamform signals for images of different imaging characteristics;
an image processor coupled to the beamformer in each imaging signal path and configured to produce ultrasound images of different imaging characteristics;
an extrapolator coupled to the image processor and adapted to predict an extrapolated image by extrapolation of the ultrasound images;
an artifact filter coupled to the extrapolator and adapted to remove non-speckle artifacts resulting from extrapolation from the extrapolated image;
a speckle filter coupled to the artifact filter and adapted to perform smoothing of the speckle of the extrapolated image; and
a display, coupled to the speckle filter, and adapted to display a final image predicted by the extrapolation,
wherein the speckle filter is further adapted to decompose the extrapolated image and an image used by the extrapolator to produce the extrapolated image into a low-resolution image and a detail image containing speckle by spatial low pass filtering.
