Appendix A: Storage phosphor technology
The DenOptix QST System produces high quality X-ray images at very low doses as compared
to intraoral X-ray film. The imaging plates in the DenOptix QST Systems are much more effi-
cient at capturing X-ray energy than film. This means that the timer on your intraoral X-ray
source can be turned down to a very low level without affecting the image quality.
How storage phosphor imaging plates work
Each DenOptix QST Imaging Plate is made up of a very thin layer of tiny storage phosphor
crystals that are bonded together and coated on a flexible sheet of plastic. These storage
phosphor crystals have the ability to capture the energy of X-rays and store the pattern as a
latent image (see diagram).
