Phosphor Storage Plates (PSPs) are reusable film-sized plates coated with phosphor as the image receptor.

Phosphor Storage Plates (PSPs) are reusable film-sized plates coated with phosphor as the image receptor.

• A. Phosphor Storage Plates (PSPs)
• B. Intraoral Film
• C. Positioning Device
• D. Radiograph

Answer: (A)

The key idea is that Phosphor Storage Plates are the image receptor used in digital dental radiography. They are reusable, film-sized plates coated with phosphor that store the X-ray energy and are later read by a scanner to produce a digital image. This distinguishes them from intraoral film, which is a conventional single-use medium; from a positioning device, which is just used to place the receptor in the mouth; and from the radiograph, which is the final image created after processing.
