Preparing and Positioning the Adult and Pediatric Patient
To prepare and position the patient, follow these steps:
1. Ask the patient to remove all metal objects.
2. Ask the patient to wear a lead apron. Ensure that the apron lays flat across the patient’s shoulders.
3. Pull out at the top part of a head clamp bar to extend both bars.
4. Ask the patient to do the following:
• Move forward.
• Stand up straight in the following positions:
• For a frontal AP, facing the generator.
• For a frontal PA, facing the cephalometric sensor.
• Place both ears in between the head clamps.
5. On the control panel, press and hold to level the ear cones to the patient’s auditory canals.
Important: The head clamp will NOT extend if you pull out at the lower
part of the bar.
