Calibration
To optimize image quality, the Faxitron CT Software and the hardware requires periodic
calibration. This calibration requires the acquisition of reference images.
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 each interval shown
Image Calibration
Daily
Geometric Calibration
Every 3 months
Uniformity Calibration
Every 3 months
Each day when the system is started up 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/humidity settings.
If the system has been knocked or moved over an uneven floor, then all 3 calibrations should be
performed to maintain the image quality.
WARNING
The CT has a battery back up to move the unit without powering down, but the
system must be on mains power when capturing images, including calibration
.
Daily System Warmup and Image Calibration Sequence
Ideally, allow the system to warm up for 30 minutes before
calibration. This will ensure that the internal detector electronics
have stabilised, and the system will produce a higher quality image.
To calibrate the system at any time, click the Calibrate button on the
Startup Screen (main screen).
Then click Image Calibration.
