ARDMS SPI Exam - Topic 5 Question 34 Discussion

Comprehensive and Detailed Explanation From Exact Extract:

In pulsed-wave transducers, the thickness of the piezoelectric element primarily determines the fundamental operating frequency. Thinner elements produce higher frequencies, while thicker elements produce lower frequencies.

According to sonography instrumentation reference:

''The operating frequency of a pulsed-wave transducer is primarily determined by the thickness of the piezoelectric crystal. Thinner crystals vibrate at higher frequencies.''

Therefore, the correct answer is A: Element thickness.
