How do solid-state detectors compare in size to film and PSP plates?

• A. More bulky
• B. Smaller
• C. About the same size
• D. Much lighter

Answer: (A)

Solid-state detectors include the sensor array plus readout electronics, shielding, and a protective housing. All of that hardware inside a rigid frame adds thickness and weight. In contrast, film and PSP plates are passive imaging media—thin, flexible sheets with only a protective layer—so they stay slim and easy to maneuver in the mouth. The electronics and protective packaging of solid-state detectors make the overall unit bulkier than film or PSP plates, which is why they’re described as more bulky.
