Abstract:
1. An ultrasound imaging method for achieving transmit and receive focusing at one or more echo locations within a region of interest, the method comprising: providing one or more probes that includes one or more transducer elements for transmitting and receiving ultrasound waves; generating a sequence of spatially distinct transmit beams which differ in one or more of origin and/or angle; determining a transmit beam spacing based at least partially upon a combination of actual and desired transmit beam characteristics, wherein the transmit beam spacing is determined without substantial consideration of round-trip transmit-receive beam sampling requirements; storing coherent receive echo data, from two or more transmit beams of the spatially distinct transmit beams; combining coherent receive echo data from at least two or more transmit beams to achieve a substantially spatially invariant synthesized transmit focus at one or more echo locations; and combining coherent receive echo data from one or more transmit firings to achieve dynamic receive focusing at one or more echo locations.
