Abstract
A thinned array of ultrasound transducers includes plural transmitters configured so that each transmitter insonates one segment of a volume at a time and an array of receivers electronically aimed at and dynamically focused upon subsegments of the insonated segment. The spacing between receivers is greater than one-half the transmitted wavelength. Echoes are received in a pattern that is aligned with the insonates segment so that receiver grating lobes nearest the echoes coincide with first transmitter nulls, minimizing the deleterious effects of grating lobes.
