The typical value of pulse duration in diagnostic ultrasound is?

Explanation:
Pulse duration is the time from the start to the end of a single transmitted ultrasound burst. In diagnostic imaging, bursts are kept very brief to improve axial resolution and limit energy delivery to tissues. The practical pulse duration used in most diagnostic systems falls in the range of hundreds of microseconds up to a fraction of a millisecond. Among common option ranges, 100 microseconds to 1 millisecond best matches this typical magnitude. Shorter spans would describe bursts that are unusually brief for routine imaging, while much longer spans would degrade depth discrimination and image quality.
