Adjusting The Position Of The Sensor Head - Planmeca Proline XC Technical Manual

Chapter E - DIMAX3 DIGITAL SYSTEM ADJUSTMENT
Measure the distance between the line on the alignment ruler and the x-line on the ball phan-
tom (Fig. 97). The distance must be less than 1mm.
Tube head side
Figure 97
If the distance between the line on the alignment ruler and the x-line on the ball phantom is
more than 1mm, the sensor head position must be adjusted. Adjust the sensor head towards
the ball phantom's x-line until the distance is less than 1mm according to the instructions
given in section 4.3 "Adjusting the position of the sensor head" on page E-48. Correct only
half of the deviation, so that the deviation will be the same in both the 180° and 0° positions.
4.3

Adjusting the position of the sensor head

NOTE This section applies to panoramic units without cephalostat and pan/ceph units with
one sensor head (i.e. sensor head with quick connector mechanism). In case your X-
ray unit is a pan/ceph model with two fixed sensor heads, the position of the entire
panoramic sensor head can not be adjusted. Refer to section 4.4 "X-ray units with two
fixed sensor heads: panoramic sensor head adjustments" on page E-49.
The position of the sensor head can be slightly adjusted. Loosen the two screws that hold the
sensor head in rotating unit and move the sensor head to required position.
Loosen the screws.
