Which term refers to the part inside an extraoral cassette that converts x-ray energy into visible light, which in turn exposes screen film?

• A. Intensifying Screen
• B. Emulsion
• C. Digital Image
• D. Duplicating Film

Answer: (A)

The inside component that turns X-ray energy into visible light is the intensifying screen. When X-rays hit the screen’s phosphor coating inside the cassette, they are converted into light. That light then exposes the film’s emulsion on the opposite side, forming the image after processing. The emulsion is the light-sensitive layer on the film itself, not the device that produces light inside the cassette. A digital image involves sensors and computer processing, not traditional film-screen radiography, and duplicating film is used to copy radiographs, not exposure inside the cassette. So the term that fits is intensifying screen.
