8.3 Patient Positioning
Have patience (especially pregnant women and children)
wear a lead apron to protect themselves from residual
radiation.
Be careful not to shine the laser beam directly into the
person's eyes. Doing so may result in vision loss.
Ensure that the Nasal Positioner is left unfolded, before
adjusting the Ear Rods in the proper direction.
Correct posture reduces the shadow cast by the patient's
cervical spine and allows clear image acquisition.
Metal implants or bridges may reduce the quality of the
images.
The manufacturer recommends using a chair that can be
adjusted to a height of at least 450 mm and up to 580 mm.
Getting prepared
1. Let the patient remove all the metal objects (glasses, earrings, hairpins, braces,
false teeth, etc.). Metal objects may induce ghost images and lower image quality.
2. Have the patient wear a lead apron to protect themselves from residual radiation.
3. Use the Column UP/DOWN button in the Handle frame or use the switch option
to adjust the equipment to match the sitting height of the patient.
