1. A synthetic focus ultrasound system comprising:

  • an array of transducer elements;

    a transmitter coupled to the transducer which acts to produce transmit events by the transmission from an individual element or group of elements over the full image field;

    a receiver coupled to the transducer which receives echo signals from elements of the array in response to a transmit event;

    a plurality of delay sets used to produce from the echo signals a plurality of motion maps of discrete motion characteristics for points in the image field;

    a detector;

    a motion analyzer, responsive to the motion maps, which selects one or more motion maps for the production of an ultrasound image; and

    a display which displays the ultrasound image.
