Claim:
1. A Doppler ultrasound imaging method comprising: controlling one or more elements of a transducer array comprising a plurality of transducer elements to emit ultrasound transmission having wavefronts emanating from a point, the ultrasound transmission having a frequency of at least 1 MHz; detecting echoes of the ultrasound at each of a plurality of the transducer elements and storing data representing the detected echoes, the stored data comprising samples of the echo signals acquired at a frequency of at least 4 MHz; processing the stored data to yield in-phase and quadrature images for each of a plurality of frames, each of the frames corresponding to one of the transmissions each of the in-phase and quadrature images comprising values corresponding to pixels; and, for each of a plurality of pixels, processing the pixel values for the pixel in the frames to yield Doppler velocity information.
