ABSTRACT:
A scanning architecture that makes it possible to update only those ultrasonic transducer subelements of a mosaic transducer array that change from view to view. The configuration of the switch matrix is fully programmable. The switch matrix includes access switches that connect subelements to bus lines and matrix switches that connect subelements to subelements. Each subelement has a unit switch cell associated therewith, each unit switch cell comprising at least one access switch, at least one matrix switch, and addressing and control logic. Optionally, each unit switch cell also includes latches for storing the future switch states of the switches to be programmed. The switches themselves have memory for storing their current switch states.
