NOT associated with a low-Q transducer?

• A. Wide bandwidth
• B. Multifrequency selection
• C. Long pulse length
• D. Diagnostic pulse-wave ultrasound

Answer: (C)

A transducer's Q factor and bandwidth determine the pulse length and frequency content. A low-Q design has a wide bandwidth, meaning it can emit and receive a broad range of frequencies and produce short pulses. This broad bandwidth supports multifrequency operation and is ideal for diagnostic pulse-wave ultrasound, where short, broadband pulses improve axial resolution and allow use across multiple frequencies. Long pulse length, however, is characteristic of a high-Q design with narrow bandwidth and longer ringing, so it is not associated with a low-Q transducer.
