Abstract
An ultrasound imaging probe assembly (1a) has multiple piezoelectric elements (3) producing an array of scanned ultrasound signals and being connected by insulated conductors (4) to an electronic scanner to convert the signals to an image, the insulated conductors (4) are concentric with an inner conductor (8) and a conducting shield (7) to provide an ultrasound transducer assembly (1) of compact size, the insulated conductors are capacitively coupled to the inner conductor (8) and the shield (7), and the shield (7) and the inner conductor (8) are commonned to reference electrical potential.
