Receptor preparation - CCD/CMOS vs PSP: Which uses protective sleeve + connect to computer?

• A. CCD/CMOS
• B. PSP
• C. Both
• D. Neither

Answer: (A)

Protective sleeves are used to keep the intraoral receptor clean between patients, and the way the image data is read out to the computer differs between receptor types. Direct digital detectors like CCD/CMOS are housed in a protective cover and are designed to be used chairside with a disposable barrier sleeve; after exposure, the image is transmitted directly to a computer workstation for immediate viewing. Photostimulable phosphor plates, used with computed radiography, come as reusable plates that are placed in a protective barrier, but they require a separate scanner to read the plate and then send the digital image to a computer, adding an extra step. Because the question emphasizes a protective sleeve plus direct connection to the computer, the direct digital CCD/CMOS detector is the best fit.
