Which component in an ultrasound unit contains the memory bank?

• A. Transducer
• B. Receiver
• C. Display
• D. Scan Converter

Answer: (D)

In ultrasound systems, the image data needs to be stored and then turned into a displayable image. The scan converter handles this by holding the echo data in memory and translating it from the raw scan-line format into a two-dimensional image on the screen. It maps each echo strength to a brightness level and places every line at the correct position, which requires dedicated memory to store the frame before it’s shown. The transducer generates the echoes, the receiver processes them, and the display presents the image, but the memory that holds and organizes the image data is a function of the scan converter. That combination of storing the image data and converting it into the on-screen image is why this component contains the memory bank.
