  • RFI-protected ultrasound probe
    Patent number: 6776758
    Abstract: An ultrasound imaging system including an electromagnetically protected ultrasound TEE probe, a display for displaying ultrasound images, a housing including a transducer connector including at least one connection and a computer for processing electrical signals representative of received ultrasound echoes. The TEE probe includes a probe 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.
