Claim 2:
3. The system according to claim 1 wherein the control and processing circuitry is configured to perform synthetic aperture beamforming, for a given location, such that at least one given set of decoded receive signals associated with insonification via a given subset of the ultrasound array elements is processed by:
for each ultrasound array element of the given subset of the ultrasound array elements:
determining a set of round-trip times of flight between the ultrasound array element, the location, and the ultrasound array elements of the fixed aperture; and
respectively applying the set of round-trip times of flight to the given set of decoded receive signals;
whereby repeated use of the given set of decoded receive signals for the calculation of times-of-flight on a per-element basis when performing beamforming reduces grating lobe artifacts that would otherwise be associated with grouping array elements during time-of-flight calculations.
