11.3 Patient positioning

1. Guide the patient to the X-ray unit when you see this message.

•

The patient can sit or stand during the exposure.

NOTE

We recommend that you image patients with poor health in a sitting

position.

2. Use the height adjusting slider on the touch screen to move the X-ray

unit up or down until the chin cup is approximately level with the patient’s

lower jaw.

3. Ask the patient to grasp the patient handles.

4. Position the patient’s head so that the patient’s midsagittal plane

coincides with the midsagittal plane laser light.
