A digital scan converter is another name for which component?

• A. Image memory
• B. Pulser
• C. Receiver
• D. Analog to digital converter

Answer: (A)

Think of it as the image memory that holds and formats the echo data into a displayable picture. After the echoes are detected and turned into digital values, the digital scan converter stores those values as a two‑dimensional array of brightness levels and maps the data from the scanned lines into the rectangular pixel grid you see on the screen. It may also adjust the grayscale mapping and interpolate data to produce a smooth image. In this sense, the digital scan converter is essentially the component that creates the displayed image from the processed data. The other components have different roles: the pulser generates the ultrasound pulses; the receiver processes and amplifies the echoes; the analog-to-digital converter converts the analog echoes to digital form, but the specific function of assembling and formatting that data into a display is performed by the image memory—the digital scan converter.
