Maintenance
In principle, the detector assembly is maintenance-free; however, it is important that all
correction files are regularly updated and used for image processing. In some applications, it is
advantageous to update the offset correction file directly before each image.
Although the a-Si 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 files should be
checked and compared regularly to determine changes in bad pixels and clusters.

Cleaning
The detector and connected cables are likely to be contaminated during use. The specific
material most likely to become contaminated is the X-ray grade carbon fiber input window and
housing.

11.1.2
Cleaning the X-ray Detector
To clean the X-ray detector:
1
Turn off the X-ray detector and detach the power and communication tethered cable, if
applicable.
WARNING
When the detector system is going to be cleaned, be sure to power down
the X-ray detector and unplug the cables. Ignoring this warning may
result in explosion, fire, or electrical shock, which may result in severe
personal injury, death, or substantial product damage.
Caution
Do not use flowing liquid or immerse the detector. Doing so will short out
the electronics in the detector and destroy the device.
Caution
Do not sterilize the detector, doing so can permanently damage it.
