1. An intravascular ultrasound (IVUS) imaging system, comprising:
an IVUS catheter comprising:
an ultrasound probe; and
a catheter cable;
an extension cable different than the catheter cable, wherein the extension cable comprises:
a first connector configured for direct electrical and mechanical connection to the IVUS catheter;
a second connector opposite to the first connector; and
a cable arrangement extending between the first connector and the second connector, wherein the cable arrangement is configured for IVUS power transmission and IVUS data transmission, wherein cable arrangement comprises:
a combined electrical cable configured to carry IVUS power signals and IVUS data signals that are superposed;
a splitter for extracting the IVUS data signals from the IVUS power signals and IVUS data signals that are superposed;
a signal processor configured to process the extracted IVUS data signals, wherein the signal processor comprises an electrical buffer with gain 1 or an electrical amplifier with gain greater than 1; and
a combiner for recombining the processed IVUS data signals with the IVUS power signals.
