Question:medium

Among the piezoelectric materials, PZT crystals show better electro-mechanical conversion efficiency than Quartz crystals upto a frequency of about:

Show Hint

Standard medical imaging operates between \( 2 \text{ MHz} \) and \( 15 \text{ MHz} \), which matches the sweet spot where PZT performs optimally before internal material stress degrades its efficiency.

\( 15 \text{ MHz} \)
\( 25 \text{ MHz} \)
\( 25 \text{ kHz} \)
\( 15 \text{ kHz} \)
