Adjusting the mechanical diaphragm

The mechanical diaphragm allows for three fixed settings.
The areas displayed in blue show the intended visible volume of the X-ray
exposure.
The collimation results in minimal radiation exposure to explore
diagnostic questions in the upper and lower jaw.
You can select the desired area by simply turning the switch on the X-ray
tube assembly.
1. Upper jaw collimation (UJ)
If the "Upper jaw" setting is selected, the X-ray image will only show
the area of the upper jaw. The height of the displayed volume is
approx. 8.5 cm. The region of the lower jaw will not be included in the
image.
2. Open diaphragm
When the "Open diaphragm" setting is selected, the full volume will
be displayed in the X-ray image. No collimation occurs in this case.
3. Lower jaw collimation (LJ)
If the "Lower jaw" setting is selected, the X-ray image will only show
the area of the lower jaw. The height of the displayed volume is
approx. 8.5 cm. The region of the upper jaw will not be included in the
image.
Tip: The open diaphragm is preferable for transverse wisdom teeth
because when the upper jaw is collimated it is not completely displayed
in some cases.
CAUTION
Check for the correct diaphragm setting prior to each exposure.
IMPORTANT
If the usual volume display shows considerable deviations with an
adjusted diaphragm setting, the diaphragm may be maladjusted.
In this event, contact your service engineer.
