An alternative type of intraoral sensor is the photostimulable phosphor plate (PSP), which mimics film in its shape and thickness.
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).
