Volumetric imaging using fan-beam scanning with reduced redundancy 2D arrays
(IEEE, 2006)
Phased array processing with a fully populated 2D array produces the best image quality but requires excessive number of active parallel front-end channels. Here we explore four array designs with reduced redundancy in ...
