Which term describes the storage and playback of the last several real-time frames for review?

• A. Cine Loop
• B. Freeze Frame
• C. Field of View
• D. Comet Tail

Answer: (A)

The concept here is capturing and reviewing a sequence of the most recent real-time frames, which is the cine loop. Ultrasound systems continuously buffer a rolling set of frames so you can pause, rewind, or play back that loop to scrutinize motion, timing, and flow without having to re-scan. This is especially helpful for evaluating dynamic processes like cardiac motion or vessel flow.

In contrast, a freeze frame saves only a single still image, not a running sequence; the field of view is simply the area being imaged, not a playback function; and a comet tail is a color Doppler artifact and not a storage/playback feature. So the term that best describes storing and playback of the last several real-time frames is cine loop.
