5: Calibration
To optimize image quality, the Faxitron CT Software and hardware require periodic
calibration. During calibration a number of reference images are acquired.
On first installation the system should be allowed to reach the ambient room temperature
and a full calibration performed.
There are 3 calibrations for Faxitron CT which should be performed at the internal
shown:
• Image Calibration Daily
• Geometric Calibration Every 3 months
• Uniformity Calibration Every 3 months
Each day when the system is started the user will be prompted to complete a warmup
and image calibration. In addition, it is recommended that the system be re-calibrated
after the system is moved from one room to another room with potentially different
ambient temperature and humidity.
Note
If the system has been knocked or moved over an uneven floor, all 3 calibrations should
be performed to maintain the image quality.
Caution:
The Faxitron CT has a battery back-up which allows the system to be moved without
powering down. However, the system must be on mains power when capturing
images, including during calibration.
5.1 Image Calibration
Ideally allow the system to warm up for 30 minutes before calibration. This will ensure
that the internal detector electronics have stabilized, and the system will produce a
higher quality image.
To calibrate the system at any time, click the Calibrate button in the Home
Menu then click Image Calibration.
