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.
Calibration
To have the best image performance, the raw image data generated by the detector
should be corrected at the host by using a flat field (offset and gain) correction. As the
offset (dark) calibration signal depends (amongst others) on ambient temperature
conditions of the detector, it is commonly accepted good practice to generate these
calibration images frequently at times that the X-ray source is switched off. It is
recommended to re-calibrate the gain correction image at least once per year, or
whenever the X-ray tube is exchanged or anything changes in the X-ray imaging
geometry (e.g. the distance between the X-ray source and the detector).
The detector can contain deviating pixels. To have the best possible image quality it is
advised to perform a defect pixel correction in the host system. It is recommended to
create a defect pixel calibration map at least once every year, or more frequently in
case of heavy use.
To verify if the detector still operates according specification it is advised to measure
on regular base the following performance parameters of the detector: dark reference,
noise performance, flatfield reference, saturation dose and MTF performance.
Open Source Software Licenses
Teledyne DALSA X-ray detector firmware contains open source software provided
under different open source software licenses. More information about these open
source licenses can be found in the documentation that accompanies the firmware.
Recycling
EU Waste Electrical and Electronic Equipment (WEEE) Directive
The European Union (EU) implemented the EU WEEE Directive 2012/19/EU
requiring producers of electrical and electronic equipment (EEE) to manage and
finance the collection, re-use and recycling of the products that producers placed on
the EU market after 13 August 2005. The EU Commission adopted the Implementing
Regulation (EU) 2019/290 establishing the format for registration and reporting of
producers of EEE to the register. The goal of this directive is to minimize the volume
of EEE waste disposal and to encourage re-use and recycling at the end of life.
The WEEE symbol on the product indicates that the product cannot be disposed of
with other household or municipal waste. Teledyne DALSA has labeled its products
with the WEEE symbol to alert the customers that products bearing this label should
not be disposed of in the landfill.
