block holder (only PAN/CBCT version), move the U-arm, turn the positioning lasers on and off and activate the X-MIND
trium medical device.
2. X-ray generator. The X-ray assembly is the source of the X-ray beam during the rotation of the U-Arm. An automatic
collimator shapes the X-Ray beam, whereas the electronic control ensures stability and accuracy of the selected loading
factors (exposure time, kVp and anodic current). A lter is used to harden the beam and remove low-energy ionising
radiations, thereby obtaining suitable radiation quality whilst reducing its dose absorbed by the patient. The lter’s
material is aluminium for PAN and CEPH exams, aluminium + copper for CBCT exams.
3. Sliding body. The sliding body is the mobile part of the column that supports U-arm.
4. U-arm. The U-Arm supports the PAN/CBCT Detector sliding group and the X-ray generator. This is the rotating part of
the medical device, which moves around the patient during the image acquisition phase ; it can as well be moved in two
horizontal directions (X and Y) by the operator during the setup of the exam, in order to obtain the best superimposition
between the patient’s head anatomy and the diameter of the Field of View (FOV).
5. Detector sliding group. It contains detectors that allow to acquire PAN and CBCT images.
6. CBCT detector. This at panel detector is indicated for use in generating radiographic images of the maxillo-facial region,
more specically it is dedicated for CBCT acquisitions.

For the panoramic group and the cephalometric group, the operator can still modify the loading factors by means of dedicated
sliders.
!
WARNING :
Only physicians or dentists properly trained can modify the loading factors from the predened values for the panoramic and
cephalometric groups taking into account the effects on the image quality, increase/decrease of radiation dose and the needs of the
clinical task.
On the contrary, for the CBCT group, the operator cannot modify the anodic current and tube voltage, but can just select the
quality of the 3D reconstruction between three protocols:
· Standard quality
· Medium quality
· High quality
The X-ray exposure time of the scan increases from the standard quality to the high quality involving both the improvement
of the image quality and the increase of the radiation dose to the patient.
