  • Page 59: Appendix

    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).

  • Page 60: Appendix B: Lighting Conditions For Handling Or Erasing Imaging Plates

    The DenOptix QST scanner further excites the phosphor crystals to an unstable state by exposing them to a red laser. The phosphor crystals then release a blue light and return to their stable ground state. The DenOptix QST scanner reads this blue light and, with the imag- ing software, produces an image.
  • Page 61 Additionally, it is very difficult to judge the intensity of sunlight. Loading carousels under sunlight must be avoided. If you cannot darken your mounting area to 20 lux or less, contact your local Gendex representative for suggested mounting times.
  • Page 62 Gendex DenOptix® QST 4. Using the exposure conditions outlined in Section 5.1, expose each imaging plate. If pos- sible, place an object, such as an extracted tooth, in the path of the X-ray beam. 5. Turn on your erasing light source. We recommend a light box or a minimum l00-watt incandescent light bulb (see Section 5.2).

  • Page 63: Appendix C: Optional Printer

    Thermal printers print in shades of grey with at least 64 levels. Thermal printers use a special type of paper which guarantees a print life of about 3 years. Dye sublimation printers Suitable for high printing quality whenever the DenOptix QST System is used in combination with an intraoral camera. Laser printers If a Laser Printer is adopted, contact the Printer manufacturer or a representative to make sure that it can achieve at least 256 gray shades.
