1.5 Panoramic beam adjustment
NOTE In case the X-ray unit is equipped with fixed sensor head, adjust the panoramic X-ray
beam according to the instructions given in section 1.6 “X-ray unit with fixed primary
collimator - primary collimator adjustment” on page E-14.
Manually position the C-arm to a convenient position for viewing the sensor head. Place the
beam alignment tool to the sensor head alignment tool upside down.
Darken the room sufficiently so that you will be able to see the image of the radiation beam on
the alignment tool (it is fluorescent and will glow when the radiation beam strikes it), but not so
dark that you cannot see the borders of the alignment rectangle.
Select kilovolt and milliampere values high enough to enable the radiation beam to be seen in
the darkened room. The actual values will depend on how dark the room is.
To enter the calibration mode first touch the i-field on the
Main
display. Select Technical cali-
brations (i600) from the list on the display. The password to the Technical calibrations mode
is asked when the Technical calibrations mode is entered for the first time after switching the
unit on. The password is 1701.
