Which device makes grayscale imaging possible by transferring incoming echo data into a display format?

• A. Scan Converter
• B. Analog Scan Converter
• C. Digital Scan Converter
• D. Digital Memory

Answer: (A)

Grayscale imaging is created by turning the raw echoes captured along each scan line into a displayable image. The device that performs this transformation is the scan converter. It takes the echo data and places it onto a rectangular display grid, assigning brightness levels based on how strong each echo was. Whether implemented as an analog or a digital system, the key function is converting the incoming echo information into a format the monitor can show as a grayscale picture. Digital memory may store frames, but it doesn’t by itself generate the grayscale image—the scan converter is responsible for that crucial transfer from echo data to display.
