6.5.5 Panoramic collimator calibration
NOTICE! With Pan unit (no 3D option) this calibration is
done by adjusting the collimator.
NOTICE! There is a 6-8 second delay after initially
pressing the exposure button before exposure occurs.
1. Attach the panoramic sensor.
2. Select the PAN Col program.
3. Press Patient Positioning .
4. Take an exposure.
5. The status is displayed on the image captured in the im-
aging software, how much the height needs to be adjust-
ed and in which direction.
6. Adjust the height of the PAN sensor and check the tilt and
position of the collimator. Make adjustments and take
new exposures until calibration result “passed” is
achieved.
First two lines are for DIN and the rest for the IEC standard.
Field of useful beam (h x w): 126.0 x 129.2 mm result according to DIN.
Field of useful beam max. (h x w): 138.7 x 140.3 mm DIN limit.
X-ray field (h x w): 126.7 x 131.0 mm result according to IEC.
X-ray field max. (h x w): 138.7 x 140.3 mm IEC limit.
X-ray field discrepancy (up+down+left+right): 12.9 mm result according to IEC.
X-ray field discrepancy (up+down+left+right): 22.7 mm IEC limit.
