Which element serves as the electrical conduit between the PZT and the ultrasound system?

Explanation:
Electrical signals must reach the piezoelectric element to generate ultrasound, and those signals travel through conductors from the system to the PZT. The wire provides this direct electrical pathway, delivering the drive voltage to excite the PZT and carrying the returned signal back to the system. The matching layer is for acoustic coupling, not electrical conduction; the case is the housing, and the shield is there to reduce noise rather than serve as the primary signal path. So the wire is the essential electrical conduit between the PZT and the ultrasound system.
