Temporal resolution is defined by the time required to complete what?

• A. Frame
• B. Echo
• C. Pulse
• D. Scan line

Answer: (A)

Temporal resolution is about how quickly we can image changes over time. It is determined by how long it takes to generate a single image frame. In ultrasound imaging, one frame is built from many scan lines: the system sends a pulse, waits for echoes along the chosen depth for each line, and repeats across all lines to form the displayed image. The total time to complete all lines for the frame—the frame time—sets how often a new frame can be shown. A shorter frame time means a higher frame rate and better temporal resolution, allowing us to track fast-moving structures more accurately. The other terms refer to parts of the process (the received signal, the emitted pulse, or a single line of data) but do not represent the total time to produce one complete image frame.
