ABSTRACT:
A cooling system for an ultrasonic imaging system is provided, the ultrasonic imaging system having a probe for transmitting and receiving acoustic signals through a tip of the probe to and from biological tissue contacting the tip at an outer surface of the tip. The cooling system includes a conduit for circulating cooling medium therein, and a heat exchanger in fluid communication with the circulating cooling medium and having means for removing heat from the circulating cooling medium, wherein at least a portion the conduit is in proximity to or contacts the outer surface of the probe tip. In a first embodiment the conduit includes an inlet fluid line extending from the heat exchanger to the tip of the probe for providing the circulating cooling medium from the heat exchanger to the probe tip, and an outlet cooling line extending from the tip of the probe to the heat exchanger for providing circulating cooling medium from the probe tip to the heat exchanger. In a second embodiment the heat exchanger is housed in the probe. In a third embodiment, the probe is housed within a housing, wherein a portion of the conduit extends from the tip of the probe along an external surface of the housing.
