An apparatus for detecting vulnerable plaque in a blood vessel includes an intravascular probe, and a slip ring at a proximal end of the probe. The slip ring has a stationary portion and a spinning portion. An ultrasound transceiver board is mechanically coupled to the slip ring's spinning portion for communication with an ultrasound transducer, also within the probe. A transmission line extends between the ultrasound transducer and the ultrasound transceiver board.
