Intracavity Probe With Continuous Shielding of Acoustic Window

摘要

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.
