6.8 Cephalometric examination
There is no rotation of the tube-head (X-ray generator) support arm and
sensor holder for the cephalometric examination.
Various projections are possible for the cephalometric examination. On
the basis of the image format selected and the projection chosen, the
primary diaphragm will automatically place itself in the correct position,
at the same time as the secondary collimator and the digital sensor.
The Cephalometric examination is fitted with a Soft Tissues 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
overexposed and so not visible.
The I-Max Touch makes different kinds of exposures, according to the
type of selection made:
18x22
