Abstract
An acoustic/video processing stack of a plurality of substantially identical acoustic/video processing stacks is provided for attachment to a processing stack backplane and which together generate a VGA signal for display of a three-dimensional acoustic image. The acoustic/video processing stack includes a two-dimensional array of transducer elements, a companion chip block coupled to and adapted to transceive acoustic signals under a time-division multiplexed format through the transducer elements and to provide a portion of the VGA signal together generated by the plurality of acoustic/video processing stacks and a backing block disposed between the two-dimensional array and companion chip block and adapted to acoustically isolate the two-dimensional transducer array from the companion chip block, said companion chip block and backing block being of a size and diameter substantially the same as the two-dimensional transducer array.
