What are the typical values of pulse duration in microseconds?

Pulse duration refers to the time that an ultrasound pulse is "on" or actively transmitting. This parameter is crucial in sonography as it influences the axial resolution of the ultrasound image. In diagnostic ultrasound, the pulse duration typically ranges from about 0.3 to 2 microseconds.

The selected range aligns with common clinical ultrasound techniques, which use short pulse durations to enhance resolution and improve image quality. A shorter pulse duration results in a narrower pulse, which can resolve smaller structures and improve detail in the imaging process.

While other ranges may reflect pulse durations found in specific other applications or different imaging techniques, the range of 0.3 to 2 microseconds represents what is most commonly observed in standard diagnostic sonography practice. In summary, the correct range reflects the necessary characteristics of an effective ultrasound pulse for accurate imaging purposes.
