8 Calibration and adjustment
8.1 Introduction
Calibrations and quality checks are performed by taking
exposures of calibration tools. The system does needed
adjustments according to the image data captured. For
panoramic and cephalometric quality checks the quality is
visually evaluated by the operator.
Resulting from the each calibration is an image containing
calibration results, telling the operator how to proceed with
the calibration and adjustment procedure. In addition to the
calibration name (e.g. Adjustment panCol) the images
contain image data sampled during the calibration,
adjustment instructions and a "Passed / Not Passed /
Failed" calibration status.
- Passed means that the calibration program is suc-
cessfully done. Move on to next calibration.
- Not passed means that adjustment is still needed.
Follow the instructions the image (if any) and take
another exposure. Some calibration programs are
iterative and demand a few repetitions.
- Failed means that the system could not decide
what adjustment should be done in order for the
calibration to succeed. This calibration status is al-
ways the result of some error condition. Taking an-
other exposure will not help. The image may give a
hint on what the problem is (e.g. no radiation, colli-
mator severely tilted, image data corrupted…).
Contact service if the problem persists after restart-
ing the unit and PC.
