5.13.1. Orthoralix
9200
The following lead plates supplied with the system allow for
different Ceph X-rays formats:
(a)
24 x 18 cm vertical asymmetric for latero-lateral projection
(b)
18 x 24 cm horizontal for latero-lateral projection
(c)
24 x 18 cm vertical symmetric for antero-posterior or postero-
anterior projection
(d)
30 x 24 cm vertical symmetric for all projections
Two of the above listed formats can be installed, normally one for
the latero-lateral projection and one for the antero-posterior/postero
anterior projection.
To install the selected formats on the collimator, proceed as follows:
(1)
Remove the front cover (a) of the tubehead by unscrewing
the two screws (b) and by disengaging the spring latches
from the rear cover (c).

Two lead plates are already mounted on the plate:
- the 24 X 18 cm vertical asymmetric for the latero-lateral
projection in the position (g).
- the 24 X 18 cm vertical symmetric for antero-posterior or
postero-anterior projection in the position (h).
Please ask to the user which ceph formats are more convenient
among the available and, if necessary, replace the one (s) already
mounted.
Before remounting the tubehead front cover, adjust the X-ray
field of the Ceph formats as described in the Section C.
