An ultrasonic transducer array comprising individual transmit MUT elements and receive MUT elements includes the transmit MUT elements and the receive MUT elements distributed in two dimensions over the array. By using different MUT elements for transmit and receive operation, each MUT element can be independently optimized for either transmit operation or receive operation. Furthermore, by independently optimizing the MUT elements for either transmit or receive operation, the same bias voltage can be applied to the MUT elements, thereby simplifying the bias circuitry associated with the MUT transducer array. Alternatively, because the MUT elements are independently optimized for transmit and receive, different bias voltages can be applied to the transmit and receive elements, thus providing further optimization of the elements.
