Collimator Calibration; Pan Pixel Calibration (3D Sensor) - KaVo ORTHOPANTOMOGRAPH OP 3D User And Installation Manual

9.6.8 Collimator calibration

This program calibrates the PAN/3D collimator.
No calibration tools are required when performing this calibration.
NOTICE! This calibration produces X-rays. Protect yourself from radiation.
NOTICE! The X-ray beam size for 3D imaging is verified during this calibration.
1. Select Collimator calibration from the Calibrations menu.
2. Protect yourself from radiation.
3. Press and hold the exposure button down to take the calibration image.
4. When the exposure warning stops and the program end tone is played, the program
is complete.
5. The calibration image appears on the GUI.
NOTICE! If the collimator calibration fails and the GUI informs you to adjust
the height or tilt of the collimator, adjust the collimator according to chapter
PAN/3D Collimator adjustment
NOTICE! If the collimator calibration fails and the GUI informs that the
collimator plates are not parallel, the collimator plate movement may not be
working properly. Check that the collimator plates move freely by moving
them by hand.
6. Acknowledge the calibration result by pressing the OK button.
NOTICE! Repeat the Device geometry calibration if any mechanical
adjustment was required.

9.6.9 PAN pixel calibration (3D sensor)

This program calibrates the 2D/3D sensor for Panoramic imaging.
No calibration tools are required when performing this calibration.
NOTICE! This calibration produces X-rays. Protect yourself from radiation.
1. Select PAN pixel calibration (3D sensor) from the Calibrations menu.
