The present invention relates to systems and methods that enable high frequency intraluminal imaging, such as IVUS or intra-cardiac echography (ICE), by reducing an amount of circuitry and wiring required to control the functions of one or more transducer array elements of an intraluminal device (e.g. catheter, guidewire, probe, etc.). In particular, aspects of the invention provide for selectively grouping transducers of an array that receive bias control from bias control circuitry and that are controlled by transmit and receive circuitry (also referred to as pulser/receiver circuitry). The selective grouping of the invention allows the same transmit and receive circuitry to stimulate one or more transducer elements to transmit signals while stimulating one or more other transducer elements to receive signals. Since a single transmit/receive circuit can, in accordance with the invention, drive transmit/receive functions of multiple transducer elements, less wiring is required to interconnect the transducer and the overall the size of imaging core can be reduced. As a result, systems and methods of the invention enable higher frequency imaging while maintaining a smaller device footprint capable of, e.g., traversing the lumens of the vasculature.
