Which term refers to a solid-state image sensor used in intraoral digital imaging?

• A. Cassette
• B. Cephalometric Film
• C. Charge-Coupled Device (CCD)
• D. Digital Image

Answer: (C)

Intraoral digital imaging relies on a solid-state detector to capture the image. A Charge-Coupled Device is a semiconductor image sensor that converts the light signal (from the X-ray interaction with a scintillator) into an electrical charge and then reads it out to create the digital image. This is what makes it an image sensor, unlike a cassette (film-based), cephalometric film (a type of film for head radiographs), or a digital image (the resulting picture, not the detector itself). Some modern systems use other sensors like CMOS, but CCD is the classic term for this solid-state image sensor in many intraoral units.
