ADJUSTING AND CALIBRATING X-RAY
BEAM
To do this, loosen the three screws that hold the sensor in position and carefully move the
sensor towards the x-line on the ball phantom until the distance is less than 0.5mm.
Correct only half of the deviation, so that the deviation will be the same in both positions
(C-arm pos. 1 and 3).
Figure 27
Tighten the screws.
Accept the new C-arm positions (pos. 1 and 3) and exit the arm calibration mode by
touching the green check button in the bottom right corner of the Arm calibration display.
Figure 28
NOTE Repositioning the sensor will move the beam position, i.e. you will have to start again
from Step 1, see section 2.4 "Step 1: Adjusting the X-ray beam position" on page C-9.
When C-arm positions 1 and 3 are symmetrical, remove the alignment ruler and proceed
to Step 5.
