In automatic exposure programs you will get three or four
exposures in one image depending on the program you
use.
Ask the patient to close their lips on the bite piece,
swallow, and remain as still as possible. Tell the patient
that the C-arm will rotate backwards and forwards three
(or four) times so that they do not move before the end of
the exposure cycle.
Move to a protected area. In case you do not have a
protected area available, move at least two meters (seven
feet) from the X-ray. Protect yourself from radiation.
Press and hold down the exposure button for the duration
of the exposure cycle. The C-arm will rotate backwards
and forwards three (or four) times. During the exposure
the radiation warning lights on the exposure switch and on
the control panel will come on and you will hear the
radiation warning tone.
You can release the exposure button between the
exposures. If you release the button during the exposure
the program will be interrupted.
Maintain audio and visual contact with the patient
and unit during exposure. If the C-arm stops
moving during exposure, release the exposure
button immediately.
At the end of the exposure cycle open the temple
supports and guide the patient from the unit. Note that you
may have to move the C-arm before the patient can be
guided from the unit. To move the C-arm press one of the
C-arm rotation buttons.
If a large number of exposures is taken in rapid
succession the X-ray tube may overheat and a
cooling time will flash in the display (e.g. 00:42).
The cooling time indicates the delay before the
next exposure can be taken.
The image will be shown on the computer screen. Note
that you must accept the image by clicking the "OK"
button - only accepted images will be stored in the
database. Refer to Dimaxis User's Manual.
