3D geometry calibrations
These programs create the calibration data for reconstructing 3D images.
NOTICE!
This calibration produces X-rays. Protect yourself from radiation.
NOTICE!
The list of available calibrations depend on the device configuration and country
specification.
Perform the calibrations in this order, the instructions are the same for all programs:
• 3D geometry calibration, 5x5 FOV
• 3D geometry calibration, 6x9 FOV
• 3D geometry calibration, 8x8 FOV
• 3D geometry calibration, 9x11 FOV
• 3D geometry calibration, 9x14 FOV
Geometry Calibration Phantom is required when performing these calibrations.
1.
Attach the Geometry Calibration Phantom to the device.
2.
Select a
3D geometry calibration
from the Calibrations menu.
3.
Protect yourself from radiation.
4.
Press and hold the exposure button down to take the calibration image.
5.
The calibration results appear on the GUI.
NOTICE!
This will take several minutes.
6.
Acknowledge the calibration by pressing the
OK
button.
7.
Repeat the calibration for the remaining FOV sizes.
