2.5.5.7 Positioning of 3D image acquisition
* Warning
• Do not look directly into the positioning beam although the power output (Class 2) is at
the level in which adverse effect on the eyes can be avoided by blinking.
* Caution
• Positioning beam is a laser beam. Be careful not to direct the positioning laser beam into
patient's eyes. Also, advise the patient not to look directly into the beam.
• To minimize X-ray exposure, properly position the patient.
• If the rotating arm is deviated from its correct position, it may cause complications during
the procedure. Be sure to return the arm to its reset position and then retry.
1. Aligning the positioning beam
Align the horizontal position of the image acquiring area.
Fix the forehead support to the top and the up-down positioning unit to the bottom.
Press the positioning beam switch. The rotat-
ing arm unit will move to the positioning point
and the beam will be emitted. The intersection
point of the emitted median beam and the
medsagittal vertical beam will be the center
ofFOV.Movetherotatingarmandthehead
