Primary Collimator Angle Adjustment - Planmeca ProMax Technical Manual

Chapter E - C-ARM AND IMAGING ARM

2.4 Primary collimator angle adjustment

NOTE In case the X-ray unit is equipped with a fixed sensor head, adjust the primary collima-
tor angle according to the instructions given in section 2.13.1 "Fixed primary collima-
tor: Adjusting the primary collimator angle" on page E-57.
WARNING
Do not adjust the angle of the primary collimator mechanism while
X-rays are being generated, i.e. when you press the exposure
switch. Check the beam position, adjust the angle, and then
recheck the position. If the beam is still misaligned, repeat the pro-
cedure.
In case the beam is not vertical, the primary collimator can be rotated. Open the primary colli-
mator mechanism by rotating the primary collimator screws located behind the blades so that
you can see the two attachment screws (Fig. 18 and Fig. 19, 1). Loosen the screws and rotate
the mechanism (Fig. 18 and Fig. 19, 2) until the beam is correctly positioned. Tighten the
screws and check the beam. Repeat the procedure described above until the beam is cor-
rectly positioned.
