Abstract: An ultrasound probe has a transducer array which is moved to scan a patient with ultrasonic energy. The array is located in a fluid chamber (42) which is enclosed by an acoustic window end cap (34). The acoustic window cap is coated with a thin conductive layer (38) which shields the transducer and its motive mechanism from EFI/RFI emissions. The conductive layer is coupled to a reference potential.
