REFERENCE MANUAL
11.0 Maintenance
In principle, the X-ray Detector assembly is maintenance-free, however; it is important that all
calibrations are regularly performed and used for image processing.
Although the a-Si X-ray Detectors are resistant to X-rays they can exhibit degradation over time
when exposed to high X-ray dose environments. Sensitivity and uniformity may change
depending on the weekly exposure duration and X-ray dose. Therefore, the pixel correction
maps should be checked and updated regularly.
11.1 Cleaning and Disinfecting
The X-ray Detector is likely to become contaminated during use. The specific material most
likely to become contaminated is the X-ray grade carbon fiber input window and housing.
11.1.1 Material Compatible Chemicals for Cleaning and Disinfecting
All chemicals listed below are approved for use can be used for cleaning and disinfecting
X-ray Detector surfaces. To achieve full cleaning and disinfecting results, perform the
procedures in Section 11.1.2 and Section 11.1.3 for each cleaning product.
A list of chemicals is presented below:
• CAVI-Wipes from Metrex
• Isopropyl Alcohol
• 70% aqueous solution
• Mild Soap and Water
• Ethanol 70%
• Chlorine Bleach, 3% aqueous solution
• Quaternary Ammonium Components
• Steris Coverage Plus NPD
• 1 part Coverage Plus NPD to 255 parts Water
WARNING
When the X-ray Detector system is going to be cleaned or disinfected, be
sure to remove the battery pack. Ignoring this warning may result in
explosion, fire, or electrical shock, which may result in severe personal
injury, death, or substantial product damage.
