3.
Install the double cone calibration tool.
4.
Take an exposure.
5.
Repeat the calibration until calibration result “passed” is achieved.
9.3.2 Panoramic pixel calibration
NOTICE!
The pixel calibration results are sensor specific. If the x-ray unit is
equipped with separate panoramic and cephalometric sensors, the cephalometric
sensor cannot be used for panoramic imaging without re-calibration (and vice
versa).
NOTICE!
Re-do panoramic pixel calibration, if cephalostat sensor is moved to
panoramic side or the sensor is changed.
