Preparing the patient (refer to Figure 2 and Figure 3)
1.
Ask the patient to remove all metal objects located in the zone
involved in radiography (necklaces, earrings, spectacles, hair-clips,
movable dental plates etc.).
Make sure that there are no heavy articles of clothing (such as
overcoats, jackets, ties, polo-neck sweaters, etc.) in the radiography
zone.
2.
Have the patient put on the protecting apron or similar protective
devices in accordance with the regulations in force in the various
countries, making sure that it does not interfere with the trajectory
of the X-rays beam.
3.
Bring the patient in standing position up to the chin support and,
using the handle, release the brake button (24) in order to position
the slider so that the chin support resting plane is aligned with the
patient's chin.
4.
Position the patient in the skull clamp with the chin resting on the
appropriate support and rest the hands on the side handles; have
the patient bite with the incisors in the groove of the bite block
mounted on the appropriate rod, making sure both upper and lower
anteriors are set in the groove of the bite piece.
5.
Press the laser centring device activation button (20). When this is
done, two crossed beams of light illuminate both the sagittal median
line (45) and the horizontal line for the Frankfurt plane reference
(46).
The centring device stays illuminated for about 40 seconds; if this
time is insufficient to carry out the centring operations, the
activation button (20) may be pressed again.
6.
Bring the height of the skull-clamp a little above the patient's orbital
bone and centre the patient until the position of perfect alignment
with the Frankfurt and sagittal median lines is obtained.
The Frankfurt plane light beam must be adjusted for height in
relation to the patient's size; the adjustment is made by acting on
the appropriate knob (18).
In order to check the patient's centring, the operator can tilt the
mirror towards himself, thus obtaining a front view of the patient.
Lastly bring the patient's head into contact with the two temples
clamp rods (7) by acting on the appropriate knob (9).
7.
After the head has been positioned, the patient has to make a
movement with his feet towards the stand. This will give better
distension of the spinal column in the cervical region, eliminating
white ghosting of the spine on the radiograph in the zone of the
lower incisors.
8.
Check centring again, advise the patient to close mouth and eyes,
ask then to swallow and
bring the tongue against the palate
and
remain motionless for the exposure.
