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.
NOTICE
The open diaphragm is preferable for wisdom teeth lying transversally,
because when the the upper jaw is collimated it is not completely displayed
in some cases.
CAUTION
Check for the correct diaphragm setting prior to each exposure.
You can select the desired area by simply turning the switch on the X-ray tube
assembly.
1 Upper jaw collimation
If the "Upper jaw" setting is selected, the X-ray image will only show the
area of the upper jaw. 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
If the "Lower jaw" setting is selected, the X-ray image will only show the
area of the lower jaw. The region of the upper jaw will not be included in
the image.
NOTICE
If the usual volume display shows considerable deviations with an
adjusted diaphragm setting, the diaphragm may be maladjusted.
Contact your service engineer in such cases.
