For the daily image calibration ensure the chamber is completely empty, including the foam
tray. Check the box to confirm the chamber is empty and proceed by clicking Start.
During warmup and calibration, X-Rays may be generated. During X-Ray generation, a
:Cancel”
button will be made visible to allow a user the option to stop X-Rays through software or touch
control panel.
Geometric Calibration Sequence
Geometric Calibration ensures the system is set up correctly to perform the highly precise
reconstruction of the CT images (3D). This can be performed at any time to ensure image
quality but must be conducted at least every 3 months.
If the 3D image quality degrades at any time, visible rings in the image for example, conduct a
geometric calibration.
Go to the main screen and click on the Calibrate button, as before, and then select Geometric
Calibration.
