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-
i
cally, select the X-ray station�
The parameters, imaging volume and patient
shape, are preselected according to the
patient�
Check the parameters�
i
Single-click on to open the flyout for setting
the parameters� The changed parameters are
immediately synchronized with the device�
If the preselected parameters are correct,
i
continue 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�
Image volume "Normal"
Size (W x H): approx� 100 x 85
mm
Image volume "Child"
Size (W x H): approx� 100 x 70
mm
Image quality
HQ image
An improved signal/noise ratio
is achieved via an extended
exposure time�
SQ image
This setting is used for stan-
dard images�

Patient type
The selection of patient type depends on the
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
Large patient
Average patient
Small patient
Child (< 13 years of age)
Jaw arch
The selected jaw shape affects the rotational
behavior of the C-shaped arm during image ac-
quisition� This enables an image with an ideal
layer position to be captured even on a particu-
larly narrow or wide jaw�
Normal jaw arch
Narrow jaw arch
Wide jaw arch
Child's jaw arch
