Which technique involves magnifying a region of interest after image acquisition?

• A. Read-zoom
• B. Frame averaging
• C. Persistence
• D. Compression

Answer: (A)

Magnifying a region of interest after image acquisition is read-zoom. This is a display-time magnification that lets you zoom in on a chosen area on the workstation to inspect details more closely without changing the original data. It differs from frame averaging, which enhances image quality by combining multiple frames during acquisition to reduce noise; persistence, which extends the display of frames to help visualize motion or continuity; and compression, which reduces the data size for storage or transmission. Read-zoom simply enlarges the display of the selected area, making it the best match for post-acquisition magnification.
