Adjusting the position with the positioning
beams
The positioning beams use class 1 laser
beams. Although these can dazzle the
patient, they are safe and will not damage
the eye.
For CBCT images it is sufficient to per-
form positioning based on the mid-sagit-
tal plane.
For all other image types the patient
needs to be positioned more accurately
with the aid of the following steps.
The alignment of the upper canine X-ray
positioning beam is crucial for the image
quality of panoramic images.
Check to make sure that the patient has closed
❯
his/her eyes.
If necessary, correct the height of the unit
❯
again.
Activate the positioning beams with the
