6.8 Cephalometric examination
There is no rotation of the tubehead (X-ray generator) support arm and
cassette holder for the cephalometric examination.
Various projections are possible for the cephalometric examination. The
diaphragm positions automatically according the cassette format and the
projection selected.
The cephalometric examination uses an adjustable filter called soft tissue
filter (STF). This filter reduces the dose in areas with low bone content
and highlights the patient's profile which, under normal conditions,
would be over-exposed and so not visible.
The STRATO X makes different kinds of exposures, according to the type
of cassette used:
8"x10"
Asymmetrical
for Latero-Lateral
8"x 10"
Symmetrical for
Antero-Posterior
and Postero-
Anterior
10"x 8"
Asymmetrical
for Latero-Lateral
12"x 10"
Symmetrical
for Latero-Lateral
NOTE:
The size of the cassette is not automatically recognized by the unit but
must be selected by the operator.
NOTE:
The cephalometric examination may
also be used for radiographies made to
determine the current state of bone
calcification. For example, the
hand/wrist group can be X-rayed as
shown in Figure 36. To perform this
kind of exposure, the ear rods and
nose rest must be positioned as for the
postero-anterior cephalometric
examination.
To perform this kind of examination,
the exposure parameters allowed by
current regulations can give an
overexposure film. It is recommended
to use a cassette having a medium
type intensifying screen or a cassette
with only one screen.
An alternative can be to set technique
factors at 60kV, 8mA, 0.5sec.
