ABSTRACT:
Active thermal conduction of a transducer array at the distal end of an imaging probe maintains the temperature of the transducer array below a predetermined limit so as not to damage human body tissue. A thermally conductive rotor is connected between the back face of the transducer array and a stator that behaves as a heat sink. A dual ball bearing arrangement is placed near the rotor/stator interface to allow rotation of the transducer array while providing thermal conduction. An optional layer of oil may be placed between the rotor and the stator to promote heat transfer.
