Abstract:
An electromagnetically protected ultrasound transducer, comprising:a transducer housing including an imaging sensor, an outer acoustic lens, a cable interconnect and an internal metal shield which surrounds the sensor and cable interconnect; and a cable including electrical conductors and electromagnetic cable shielding, the electrical conductors electrically connected to the cable interconnect at a first end, and the electrical conductors and the cable shielding are electrically connected to a transducer connector at a second end, wherein the cable shielding is electrically connected to earth ground via at least a shield surrounding the transducer connector; wherein further included in the transducer housing is a thin electromagnetic shield, internal to the outer acoustic lens, and electrically connected to one of the internal metal shield and cable shielding such that all elements inside a boundary formed by the transducer housing and outer acoustic lens are substantially electromagnetically protected from external electromagnetic radiation, and that the electromagnetically protected transducer maintains its flexibility for its intended purpose.
