Which term denotes the number of complete images displayed per second, typically 30–60?

• A. Frame Rate
• B. Frame
• C. Field of View
• D. Comet Tail

Answer: (A)

Frame rate is the number of complete images shown each second, measured in frames per second. In real-time ultrasound, typical frame rates are about 30–60 fps. Higher frame rates improve how smoothly motion is displayed and helps track moving structures, but achieving higher rates often requires tradeoffs such as shallower depth, a smaller sector, or fewer focusing zones, which can reduce spatial resolution or image quality. A single image is just a frame, while field of view describes how wide an area is shown, and a comet tail is an artifact, not a measure of how often images are refreshed.
