Which term means holding and displaying one frame of the real-time sequence?

• A. Freeze Frame
• B. Enhancement
• C. Dynamic Range
• D. Cine Loop

Answer: (A)

Holding and displaying a single moment from a real-time ultrasound sequence is called a freeze frame. When you activate freezing, the live image stops updating and a single frame remains on the screen, allowing you to measure, annotate, or inspect anatomy more carefully without the motion of the real-time loop.

Dynamic range refers to the span of brightness levels the image can display, from darkest to brightest, and relates to contrast rather than pausing the sequence. Enhancement involves processing steps that improve image quality, not pausing the sequence. Cine loop, by contrast, is a short sequence of frames that can be played back repeatedly, rather than a stationary single frame.
