1.5 Collimator/primary slot mechanism, Planmeca Proline EC
Panoramic X-ray unit
The collimator tube (Fig. 5, 1) is attached with screws to the radiation window frame. Under a
nut there is an inner limiting slot sheet which consists of an aluminium filter plate and lead
plates with holes. The lead plate reduces the radiation beam for the actual primary slot. The
aluminium plate filters the harmful soft radiation.
In the outer part of the collimator tube there are a slot frame (Fig. 5, 2) and a outer limiting slot
(Fig. 5, 3) which reduce secondary radiation scattering from the inner parts of the collimator
tube.
The primary slot (Fig. 5, 4) is attached to a outer limiting slot (Fig. 5, 5) which is attached to
the frame.
