Implication

Computational study demonstrates substantial element reduction in two-dimensional arrays without degrading beamforming, indicating pathways toward simpler transducer hardware.

Key Points

To reduce the number of transducer elements required in two-dimensional arrays while preserving essential beamforming characteristics.
Extended the effective aperture optimization framework from linear arrays to two-dimensional arrays by employing distinct element configurations for transmission and reception.
Simulated and compared radiation patterns between fully sampled dense arrays and sparse arrays with periodic or random element spacing across 64x64 and 128x128 grids.
Reduced the total element count in a 64x64 array by more than sixfold with minimal degradation of the radiation pattern.
Decreased the element count in a 128x128 array by more than twelvefold while maintaining beamforming properties comparable to a dense aperture.
