3. Taking an Exposure GXDP-300®
13. Carefully push the head support towards the
patient (A). Make sure that patient’s neck is
stretched and straight.
Rotate the head support knob (B) clockwise to
close the temple supports so that they gently but
firmly grip the patient’s head.
14. Ask the patient to press their lips together and
press their tongue against the roof of their
mouth.
Then ask the patient to look at a fixed point in
the mirror and to remain still for the duration of
the exposure.
The exposure takes approximately 12 seconds
for a panoramic exposure and six seconds for a
bitewing.
15. Ask the patient to step forward slightly so that
he/she is out of balance and “hanging” onto the
patient handgrips. This will force the patient to
stretch their neck as far a possible.
Check that the patient has not moved and is still
in the correct position.
16. Move at least two metres away from the unit and
protect yourself from radiation.
Make sure that you can see and hear the patient
during the exposure.
