Which device stores images at the conversion stage?

• A. Pulser
• B. Receiver
• C. Beam former
• D. Scan converter

Answer: (D)

In ultrasound imaging, the device that stores images during the conversion of raw echo data into a displayable image is the scan converter. After echoes are received and processed by the receiver and the beam former helps steer and focus the signal, the scan converter takes those line data and converts them into a two-dimensional image grid, assigning brightness values to pixels. It also holds that image in memory, allowing it to be displayed, frozen, saved, or manipulated. The other components—pulser, receiver, and beam former—are involved in generating and processing the signal, not in storing the final image.
