3.3 Beam adjustment

Select the standard 3D exposure program on the control panel of the X-ray unit.
To be able to check the radiation beam position without the C-arm moving enter the 3D
collimator calibration mode as explained below.
Beam vertical position
If the X-ray beam is too low or too high, the vertical position of the beam must be adjusted.
Select Primary collimator calibration (i610) from the display that appears when you select
Technical calibrations.
Depending on the sensor you are using, select 3D or 3D s mode Y-collimator calibration
(i61.11 or i61.13) from the list.
The position of the X-ray beam can now be checked without the C-arm moving.

The corresponding Y-collimator calibration (i61.11 or i61.13) display will appear. The vertical
position of the X-ray beam is adjusted in this mode.
Remove the sensor head from the quick connector mechanism. Attach the sensor head
alignment tool to the connector as shown in Fig. 80.
Manually position the C-arm to a convenient position for viewing the sensor head alignment
tool.
