Temporal pulse length is another name for which parameter?

• A. Lateral resolution
• B. Frame rate
• C. Temporal pulse length
• D. Pulse duration

Answer: (D)

Temporal pulse length is the duration of a single emitted ultrasound pulse—the time from the start of the pulse to its end. That makes it the same as pulse duration. In other words, it measures how long the transducer is actively sending sound for one pulse. The other terms describe different aspects: frame rate is about how many image frames are produced per second, not the length of a single pulse, and lateral resolution depends on beam width and focusing in the image plane rather than the time span of the pulse. Short pulses come from wider bandwidth (more broadband) transducers, while longer pulses have narrower bandwidth.
