1.
Check that TMJ2 examination has been selected on the sensor with
the dedicated button.
2.
With the LED of push button (30) lit up, check if the exposure data
are correct (paragraph 6.2.2), then press the X-ray button (42) during
the whole time of the exposure as the control is a dead man type,
checking the simultaneous operation of the rays signaling light (43)
and the acoustic ray signal.
NOTE:
•
X-ray emission starts with a delay of four seconds after the operation
of the exposure push-button, in order to allow the preheating time of
the tube filament and check all the set values. Arm’s rotation will
start a little in advance regarding the emission.
•
On TMJ examination, the X-ray emission does not last for all the
rotation, but it is interrupted corresponding with the central middle
part of the mouth. As a consequence, both acoustic and visual
emission signals are interrupted in accordance with the emission.
•
X-ray push button is a "dead man type"; this means that the
emission and arm’s rotation are interrupted if the push button is
released.
The push-button must be held pressed also during the
above emission interruption.
•
In case of patient’s moving during arm’s rotation, the exam has
to be interrupted releasing the emission push-button; in this way
both emission and rotation will be interrupted.
On the display will
appear the message "Press reset". The return button (32) is, then, to
be pressed to bring the machine in the starting position. The return
end is evidenced by the message "OK" that will disappear when the
button (32) is released.
•
In the event that the patient will move during TMJ2 exposure and
after TMJ1 mode already executed, it is mandatory to repeat also
TMJ1 exposures to have the complete result of TMJ1 and TMJ2 on
the same image.
