Children are more sensitive to radiation
than adults. Keep the exposure parame-
ters as low as possible taking into consid-
eration the image quality. Refer also to
the FDA information on pediatric X-ray
imaging.

Preparing an X-ray image in VisionX
Requirements:
ü VisionX is started.
ü Patient is logged-in.
ü No other image acquisitions are in progress (X-
ray or video).
Click on the required image in the menu bar
❯
(e.g.
for a CBCT image).
You can use
to call up further acquisition
types that belong to the grouping e. g.
5x5 Maxilla Molar right (see "Image acquisition
programs").
Depending on how the image acquisition
types are configured, the acquisition of
the X-ray image will start either immedi-
ately or you will first need to select an X-
ray station.
If image acquisition does not begin automati-
❯
cally, select the X-ray station.
The parameters, imaging volume and patient
shape, are preselected according to the
patient.
Check the parameters.
❯
Single-click on
out for setting the parameters. The changed
parameters are immediately synchronized with
the device.
If the preselected parameters are correct, con-
❯
tinue to work directly on the unit.
Parameter overview
Depending on the chosen image acquisi-
tion program, different parameters are
available ( e. g. the image volume is not
available for panoramic images, but the
jaw arch is instead).
Image volume
The selected image volume influences the height
of the image volume. The image volume "Child"
has a reduced height. The diameter is identical.

Patient type
The selection of patient type depends on the
for
patient's size and/or head circumference. This
means that the preset patient type may need to
be changed, if necessary.
The X-ray parameters are preset based on the
patient type (see "Appendix").
If a child is selected, then the x-ray parameters
are different:
– Reduced dose
– Shorter revolution time
– Smaller radiation field

Jaw arch
The selected jaw shape affects the rotational
behavior of the rotating unit arm during image
acquisition. This enables an image with an ideal
layer position to be captured even on a particu-
larly narrow or wide jaw.
Usage
Image volume "Normal"
Size (W x H): approx. 100 x 85
mm
Image volume "Child"
Size (W x H): approx. 100 x 70
mm
HQ image
An improved signal/noise ratio
is achieved via an extended
exposure time.
SQ image
This setting is used for stand-
ard images.
