In another embodiment, the signal from a rotating imaging transducer of the catheter is coupled to a motor drive unit by a slip ring assembly (1130). The transducer signal is passed through first (1160) and second (1220) transformers placed on opposite sides of the slip ring assembly to reduce noise from the slip ring assembly. In another embodiment, the catheter includes a position sensor to track the position of the catheter. The position sensor (320) is coupled to a second choke balun to further reduce noise.
