Name a common type of digital detector used in radiography.

• A. Photographic plates
• B. Flat-panel detectors
• C. Computed tomography tubes
• D. Radiation film badges

Answer: (B)

Flat-panel detectors are a common type of digital detector used in radiography because they offer several advantages, including high image quality, reduced patient dose, and faster image acquisition times. These detectors use thin-film transistor technology to convert X-rays into digital signals that can be processed and displayed as images. This technology allows for improved image resolution and contrast, making it easier for radiologists to analyze images and detect abnormalities. Additionally, flat-panel detectors can be integrated into various imaging systems, providing versatility and enhancing the overall workflow in medical imaging environments.

In contrast, photographic plates are used in film-based radiography rather than digital systems, computed tomography tubes are specialized X-ray tubes that are not detectors themselves, and radiation film badges are personal dosimetry devices used to monitor radiation exposure rather than to capture images.
