Which component serves as the digital memory of the ultrasound system?

• A. Transducer
• B. Scan Converter
• C. Receiver
• D. Beam Former

Answer: (B)

The scan converter is the digital memory of the ultrasound system. It stores the digital image data that comes from processing the echoes, arranging it into a 2D frame of pixels and applying grayscale mapping so the image can be displayed. In other words, after the receiver and beam former process the signals, the scan converter keeps the resulting image data in memory and formats it for display. The transducer is the source of the echoes, the receiver handles amplification and signal processing, and the beam former controls the timing and steering of the ultrasound beams—not memory.
