PREPARATIONS FOR THE EXPOSURE
User’s Manual
7.2 Selecting the cone
Select the cone to be used in the exposure. It is
recommended to use the optional long cone in order to
keep the absorbed dose to the patient as low as possible.
7.2.1 Long 30 cm (12”) cone
The long cone is attached into its position by pushing it into
the short cone and rotating it so that the red point on the
short cone and the black point on the long cone are in line.
7.2.2 HAWE film holder
The rectangular collimator can be attached to the long
cone either before the film holder or after it. When the
collimator is attached before the film holder, the film holder
rotates when the collimator is rotated.
Attach/remove: red
points in line.
In position: red and
black points in line.
