2.11 Adjustment of tomo mode patient positioning lights

Select a linear tomography (tomo) exposure and then enter the calibration mode. To enter the
calibration mode first touch the i field on the Main display. Select Calibration from the list on
the display. The password to the calibration mode is asked when the Calibration mode is
entered for the first time after switching the unit on. The password is 1701. Enter any of the
calibration modes. The tomo mode patient positioning lights are now on and can be adjusted.
Slide the alignment pin through the hole in the shoulder joint so that it goes into the position-
ing holes in the shoulder arm and column. Slide the alignment pin through the hole in the
elbow joint so that it goes into the positioning hole in the C-arm. The positions of the align-
ment pins are shown on the Fig. 66 below.
Figure 66
Slide the ball phantom into the patient positioning mechanism. Add masking tape, or respec-
tive, on the x- and y-lines of the ball phantom. You can mark the crossing points of the lights
to the tape, and the light can be seen more clearly.
The lights 1 and 2 should coincide with the ball phantom x-line, and the light 3 should coincide
with the y-line.
NOTE The lights 1 and 2 must be exactly on the x-line, otherwise they deviate from each
other. If you see two parallel lights, the lights must be adjusted, refer to section 2.11.1
"Positioning light adjustment" on page E-53.
