What term describes the amount of time it takes to complete a single frame of ultrasound information?

• A. Spatial resolution
• B. Frame rate
• C. Temporal resolution
• D. Echo time

Answer: (C)

Temporal resolution describes how quickly frames are updated in ultrasound imaging. It refers to the time required to acquire and display one complete frame—the shorter that time, the higher the temporal resolution and the better the system can track moving structures. Frame rate is the number of frames captured per second, and it is the reciprocal of the time per frame (for example, 20 frames per second means about 50 milliseconds per frame). Spatial resolution concerns the ability to distinguish two separate points in space, not time, while echo time is the duration from the emission of a pulse to the reception of the echo. So, the term that matches the description is temporal resolution.
