Title: SYSTEMS, METHODS, AND APPARATUSES FOR FLUID INGRESS DETECTION FOR ULTRASOUND TRANSDUCERS
Abstract:
Systems, methods, and apparatuses for detecting fluid ingress in ultrasound probes are disclosed. A fluid ingress may be detected by a change in resistance, capacitance, and/or current of a fluid ingress detector of a fluid ingress detection assembly. A fluid ingress detector that includes a soluble material is disclosed. A fluid ingress detector that includes a galvanic sensor is disclosed. The fluid ingress detector may provide a signal indicating a fluid ingress to an ultrasound imaging system and/or a maintenance diagnostic system.
