In manual programs you can decide how many exposures
you wish to have in one image. The minimum is one and
the maximum is four.
Between each exposure you can manually:
- change the image area
- change the exposure values (mA and kV)
- change the angle of the C-arm
- change the position of the patient.
For example, stereopair images can be taken by changing
the C-arm angle.
Ask the patient to close their lips on the bite piece,
swallow, and remain as still as possible. Tell the patient
how many exposures you will take so that they do not
move before the end of the exposure cycle.
Move to a protected area.
Press and hold down the exposure button for the duration
of the exposure. The C-arm will move once around the
patient's head. The radiation warning lights on the
exposure switch and on the control panel will come on
and you will hear a radiation warning tone. The C-arm will
then stop and wait for you to take the next exposure.
Before taking another exposure make any adjustment
necessary to the exposure settings or adjust the position
of the patient's head or the C-arm. Take the next
exposure in the same way as described above.
unit during exposure. If the C-arm stops moving
during exposure, or moves in an erratic way, release
the exposure button immediately.
If you take less than four exposures you will have to stop
the exposure procedure by touching the Finish field at the
bottom of the display.
The temple supports will automatically open. You can now
guide the patient from the unit.
When you have taken the exposure(s) the image will be
shown on the computer screen. Note that you must
accept the image in the Planmeca Romexis program -
only accepted images will be stored in the database.
