    Appendix ADC Compact cassette...
  • Page 64 Safety precautions Observe great care whenever removing the image plate from the ADC Compact cassette. Refer to the cleaning procedure described further on in this manual. Make sure that the automatic exposure control device is placed above the cassette, to prevent patients from receiving an overdose of X-rays. When it is located underneath the cassette, the backscatter protection (lead) contained in the red side of the cassette, retains a certain amount of X-rays.
  • Page 65 Description of the ADC Compact cassette The ADC Compact cassette and plate are compatible with existing X-ray tables. The exposure equipment and routines do not have to be modified when switching from conventional to digital imaging. Although compatible with existing X-ray equipment, an ADC Compact cassette is quite different from a conventional cassette.
  • Page 66 The way in which this image plate is placed into the cassette is of great importance. The side containing the white phosphor must be oriented towards the black tube side of the cassette. The dark support side is then oriented towards the red side of the cassette, as shown in the illustration below.
  • Page 67 Cleaning the image plate The inner lining of the ADC Compact cassette body is made of Bayer Makrolon polycarbonate. This ensures a high degree of protection against electrostatic charging and dust collection on the ADC image plates. Nonetheless, it is recommended to clean the image plates once a month using the following procedure: Open the cassette with the red side up.
  • Page 68 Turn the cassette over, holding the image plate in position with your other hand. Take away the cassette. The image plate remains lying on your hand. Image plate When necessary, clean extreme contamination with ADC Digital Screen Cleaner. Moisten a cellulose cloth (non-fluffy) with the cleaning agent. Rub the cleaner softly and evenly over the whole surface of the screen.
  • Page 69 Cleaning the cassettes When necessary, you can clean the outside of the ADC cassettes with soft water and soap or a detergent solution, with ADC Digital Screen Cleaner or with benzine. The inside should always be cleaned with ADC Digital Screen Cleaner. Never clean the cassette with ethyl alcohol, methyl alcohol or diethylic ether.

  • Page 72 Thanks to the red-shift of the stimulation spectrum, maximum stimulability is assured at 633 nm, the wavelength of the stimulating laser. The Agfa phosphor has excellent dark decay characteristics. Two hours after exposure, approximately 80% of the energy stored upon exposure is still available.
