5.4.7. TELERADIOGRAPHIC (CEPH) EXAMINATIONS
Tele-X-ray examinations can be performed only if the system features a tele-X-ray arm with relevant cephalostat.
Usually, these examinations are performed with the patient standing. In case of very tall or very short or wheelchair
user patients, the examination can be performed with the patient seated.
If a seat is used, make sure that the backrest or the armrests do not interfere with the correct movement of
the machine.
Remove the craniostat before performing the machine RESET.
1) Separate ear supports by working on the upper white
parts and not on the transparent sticks. Insert the ear
disposable infection control sheaths.
2) Rotate the NASION support upward.
3) Adjust the motorised column height by using the
suitable keys until the ear loops reach the height of
the patient’s external audito ry canal.
4) Make the patient access inside the cephalostat. The patient’s back must be straight and he/she must look straight
forward. Ideally, the line between the auditory meatus and the heel centre must be perpendicular to the floor
5) Close earpieces so that they slightly enter the auditory meatuses, making sure not to cause discomfort.
6) For LATERO-LATERAL projections, position the
patient’s head so that the Frankfurt plane coincides
with the horizontal light trace. For ANTERO-
POSTERIOR, POSTERO-ANTERIOR, SUBMENTO-
VERTEX, WATERS AND REVERSE TOWNE
projections, position the patient’s head according to
the angle of view provided by the selected method.
7) Rotate the NASION support downward and adjust its
depth and height in order to make it rest on the
patient’s Nasion point, without pus hing it or modifying
the previously set position.
8) Before pressing the X-ray emission button, ask the patient to look straight forward, close the teeth according to
his/her natural bite (usually corresponding to the maximum intercuspation) or according to the orthodontist’s
provision and keep lips relaxed.
