8.4. RELEASING THE EXPOSURE
ATTENTION:
The operator must observe the radiation protection guidelines (see chapter 1, Warning
and Safety Notes). Before releasing the exposure always check in the display that proper
exposure technical parameters (kV and mAs) has been set for the the patient.
Go to the area designated for the operator behind the patient (at least three meters away
from the column) or exit the room always keeping an eye on the patient, ready to
immediately interrupt radiation if necessary.
During the X-Ray emission, a yellow light is ON both on control panel and X-Ray button
and an acoustic signal is activated.
The exposure is released by keeping the exposure key pressed on the hand switch until
the acoustical and optical alarms are terminated. The longest exposure tiem in ceph
mode is of 4 seconds.
ATTENTION:
For safety reasons the operator can interrupt and terminate the X-Ray exposure any time
by releasing the exposure button on the hand switch. Premature termination is signaled
by an error message (see details in the following).
Premature termination is signaled by an error message:
Error 11: Exposure aborted during irradiation.
The patient has been partially exposed. Part of the radiograph is being available.
Examination may have to be repeated.
8.5. AFTER THE EXPOSURE
At the end of the X-Ray exposure grasp the holders at the very top with both hands. Push
the holders simultaneously outwards as far as they will go, in order to let the patient get
away from the equipment
Keep pressed the BACK key for 5 s in order to bring the carriage in Patient Entry position.
The 3D/panoramic sensor will be rotated in front of the X-Ray generator.
The resulting X-Ray exam will be available in the Oris Win DG Suite program on the PC
in a few time.
The value of the dose by area product (DAP) in mGy cm2 is indicated on display after a
panoramic exposure. Do acknowledge the DAP value with RETURN or EXPOSURE key
to proceed.
DAP computations can be enabled or disabled via service function.
8.6. COOLING DOWN OF THE TUBEHEAD
This feature protects the X-ray tube by preventing premature triggering of a new
exposure should the load requested by the next exposure exceed the available capacity.
ALARM RED LIGHT
BLINKING
The red light on the control panel keeps blinking until cool-off time has elapsed.
Other error messages
Possible malfunctions during the use generate an error message and the unit is blocked.
A list of messages are reported in chapter 12. Depending on the malfunction, technical
service might be required.
