4. Detector Maintenance
Before performing any of the following operations, make sure that the power to the detector is switched OFF.
Protecting the Detector Front Cover
The imaging area is marked on the front cover of the detector and should be treated with extreme care, as scratches
or debris in this area may produce artifacts in the X-ray image. If visible scratches are present, X-ray test images
should be taken to ensure that the scratches do not adversely affect the image quality.
Cleaning the Detector Body and Front Cover
The detector body and front cover can be cleaned with a mild, non-abrasive cleanser such as isopropyl alcohol.
Place a small amount of cleanser on a soft cloth and rub gently over the detector body surface. Wipe off with a clean
soft cloth. Do not use any harsh cleansers or solvents that may damage the paint or other finishes on the detector.
In the event of detector exposure to bio-hazardous materials, proper cleaning procedures should be undertaken prior
to removal or maintenance of the detector.
Periodic Maintenance
No periodic maintenance or service is needed.
Calibration
To have the best image performance the raw image data output from the detector should be corrected at the host by
using dark offset and flat field correction. It is advisable to re-calibrate the dark offset image as frequently as
feasible during detector standby. The raw flat field image should be re-calibrated at least once every year.
The detector can contain deviating and/or not working pixels. To have the best possible image quality it is advised to
perform a defect pixel correction at the host. Update the defective pixel map at least once every year.
