Extraoral X-ray units
Most extraoral X-ray units can be operated using the same settings as for analog films. The sensitivity of
the image plate scanner has been optimized for class 200 film-foil system.
Set the X-ray unit to sensitivity class 200 (film-foil system).
❯
If the X-ray unit does not use sensitivity class 200 (film-foil system), adapt the sensitivity of the image
❯
plate scanner using the HV-settings.
Consult with Air Techniques for the exact settings.
If deviations occur (see "14.1 Poor X-ray image"), adapt the image plate scanner to the X-ray unit
❯
(e. g. HV-setting, scanning mode).

Acceptance check
The 2D X-ray test phantom, and possibly the corresponding test phantom holder as well, is
required for acceptance tests with the PSP and sensor as receivers.
Before commissioning the unit, the acceptance test of the X-ray system must be carried out in
❯
accordance with national regulations.
The constancy tests, which must be carried out at regular intervals by the surgery personnel, are
based on the results of the acceptance test.
