Which component displays the digitized image for radiologic interpretation?

• A. X-ray tube
• B. Worker's control console
• C. Analog-to-digital converter (ADC)
• D. Display monitor

Answer: (D)

The ability to interpret a digitized radiographic image relies on the viewing device that renders digital data into a visible image. After the detector collects the signal, it is converted from analog to digital by the ADC so the computer can process and store it. But the final step for interpretation is to display that digital image on a monitor. The display monitor presents the grayscale image with appropriate brightness, contrast, and resolution so a radiologist can assess anatomy and pathology. The X-ray tube and the control console handle exposure generation and parameter setup, while the ADC handles digitization; neither alone provides the actual image to analyze—that’s the monitor’s role.
