What is the term for the individual piece of PZT that forms part of the transducer array?

• A. Crystal
• B. Tile
• C. Slice
• D. Element

Answer: (D)

In ultrasound transducer technology, the array is built from many small pieces of piezoelectric ceramic, and the individual piece within that array is called an element. Each element can be driven or receive signals separately, allowing the beam to be shaped, steered, and focused. The term “crystal” would refer to the material itself or a bulk piece, not the unit inside the array, and “tile” or “slice” aren’t standard terms for the array’s basic building block. So the correct term for the individual piece forming part of the transducer array is element.
