Question: 1 / 400

Which part of the transducer is necessary to reduce the amount of ringing of the piezoelectric (PZT) crystal?

Matching layer

Backing material

The backing material plays a crucial role in reducing the amount of ringing of the piezoelectric (PZT) crystal in a transducer. Ringing refers to the prolonged vibrations of the crystal after the transmission of an ultrasound pulse. By incorporating an appropriate backing material, these vibrations are dampened more effectively, allowing for clearer and more accurate imaging. The matching layer is responsible for transmitting ultrasound waves between the transducer and the patient's skin, the transducer housing provides structural support and protection, and the wire is used for electrical signal transmission within the transducer. However, it is the backing material that primarily addresses the issue of ringing in the piezoelectric crystal.
