6.3. ADJUSTING THE X-RAY COLLIMATOR

(A) Orthoralix 9200 / Plus / Ceph / DPI
The X-ray collimator is moveable, with four selectable positions:
- panoramic
- transcan
- latero-lateral
- antero-posterior / postero-anterior
To adjust the X-ray collimator, proceed as follow:
(1) Adjustment of the panoramic and transcan lead plates.
The X-ray field in panoramic and transcan mode shall be
horizontally adjusted so that they lie symmetrically respect
to the centre of the secondary slit: to do this, unlock the
two screws (a) and adjust the horizontal position of the
leads support plate (e) (1 mm of shift of the plate is
corresponding to 3 mm on the secondary slit).
If it is necessary to change the vertical position of the
X-ray fields, unlock the two screws (b) and change the
vertical position of the lead plate (c) to adjust the vertical
position of the panoramic X-ray field; unlock the two
screws (d) and change the vertical position of the lead
plate (f) to adjust the vertical position of the transcan X-
ray field.

(2) Adjustment of the ceph lead plates.
The X-ray fields in ceph mode (for the different formats
available) shall be horizontally adjusted so that they lie at
a distance of about 7 mm from the film edges : to do this,
unlock the two screws (g) and adjust the horizontal
position of the leads support plate (h) (1 mm of shift of
the plate is corresponding to 15 mm on the ceph casset-
te).
If it is necessary to change the vertical position of the X-
ray fields, unlock the two screws (i) and change the
vertical position of each lead plate (l) independently, so
that they lie at a distance of about 7 mm from the film
edges.
