4343W/4336W-G5/2530W-G5 X-ray Detectors
14.0 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.
14.1
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.
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.
