image plate

A photostimulable image detector used in computed tomography in place of x-ray cassettes. It gathers the energy from x-ray photons on a layer of phosphor that can repeatedly store and release information in digitized form for enhancement, recording, and image display.

The CR images were obtained using an ADC Compact (Agfa Healthcare, Mortsel, Belgium) system (12 bits per pixel) with a 35 cm x 43 cm Agfa cassette (ADCC) and a photostimulable phosphor plate (ADCC MD, 2048 x 2495 pixels).
(6) Photostimulable phosphor plates behave as energy-integrating detectors, and the output signal is proportional to the total deposited energy.
The direct system uses a sensor based on a charge coupled device (CCD) and the indirect uses photostimulable phosphor plates (PSP).
