Which statement describes the relative size of solid-state detectors compared with film/PSP plates?

• A. More bulky
• B. Smaller
• C. Similar size
• D. Heavier and bulkier

Answer: (A)

Solid-state detectors are built with the sensing element plus scintillator, optics or readout electronics, and protective housing all in one rigid unit. That combination adds thickness and bulk compared with film or PSP plates, which are thin, flexible, and housed in a cassette or scanned separately. Because of the built-in electronics and shielding, these detectors tend to be bulkier, even though they offer immediate digital output. That’s why describing them as more bulky is the best match.
