Which of the following is not associated with a low-Q transducer?

Explanation:
Low-Q transducers are characterized by a wide bandwidth, meaning they respond over a broad range of frequencies and emit short-duration pulses. This broad bandwidth makes multifrequency selection possible and is ideal for diagnostic pulsed-wave ultrasound, which relies on short, broad-band pulses to improve axial resolution and separate echoes from different depths. The clue here is pulse length: long pulse length is a feature of higher-Q transducers, which have a narrower bandwidth and longer ring-down. Therefore, long pulse length is not associated with a low-Q transducer.
