Which term refers to the storage of echo information for processing and display?

• A. Memory
• B. Cache
• C. Buffer
• D. Register

Answer: (A)

Storing echo information for processing and display is handled by memory. In ultrasound systems, the digitized echo data are kept in a main storage area (RAM) so the system can run processing steps—amplitude detection, filtering, demodulation, and scan conversion—before producing the image on the screen. Memory provides the needed space to hold entire frames or datasets during all the processing stages. Other terms describe different roles: a buffer is temporary storage to smooth data flow between components; a cache is a small, fast store for recently used data to speed repeated access; a register is a tiny storage inside the processor for immediate arithmetic. While these play important parts, the broad, ongoing storage for echo data used throughout processing and display is memory.
