Abstract

A multiplexing system enables communication between an array (2 and 6) of transducer elements (23, 24, 25 and 26; and 50, 53, 56 and 59) and a base unit (276) using a small number of wires (40; 70; and 176, 177, 178 and 179) or wireless channels. The transducer elements may be ultrasound transducer elements. For transmissions from the transducer elements to the base unit, one or more bimodal multiplexers (8; 35; 69 and 75; 172, 173, 174 and 175) are utilized. A 'bimodal' multiplexer is one which provides two shifts, with one shift being in the relative timing of signals to enable 'coherent summing' and the other shift being one that enables discrimination of signal energy generated by the different transducer elements. With respect to signaling generated at the base unit for controlling operations at the array, the number of connections is reduced by employing at least one transmit demultiplexer (232, 233, 234, 235, 236, 237 and 238) at the array for receiving a multi-element drive signal for sequencing the trans¬ ducer elements. The sequencing can be configured to achieve desired beam characteristics, such as beamforming.
