  • Page 53: Appendix A - Storage Phosphor Technology

    Appendix 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 efficient 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.

  • Page 54: How Storage Phosphor Imaging Plates Work

    DenOptix QST 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 55: Appendix B - Lighting Conditions For Imaging Plates

    Lighting Conditions for Appendix Imaging Plates Without light, storage phosphor imaging would not work. The red light from the laser scanner excites the exposed imaging plates, causing them to emit blue light. After your computer interprets the blue light and changes it into a digital image, light is used to erase the residual information from the imaging plate.

  • Page 56: Fluorescent Lights

    DenOptix QST If you cannot darken your mounting area to 20 lux or less, contact your local Gendex representative for suggested mounting times. Lighting Conditions for Erasing Imaging Plates In order to completely erase imaging plates, 99.5% of the image information must be removed.

  • Page 57: Practical Test

    Practical Test 1. Completely erase five size 2 imaging plates by subjecting them to direct, intense light for about 20 minutes. 2. Scan the imaging plates. No image should appear on the monitor. If an image does appear, repeat step 1 with a more intense light source. 3.
