Angle preselection for temporomandibular
joint programs TM2.1/TM2.2 and TM2A.1/
TM2A.2
These programs allow for angle preselection
(0°, 5°, 10°, and 15°)
for the temporomandibular joint
area.
When you touch the angle symbol in the “submenu” col-
umn (8), a submenu line for angle preselection opens.
Select the desired angle; it will now be displayed in white
in column (8).
If detailed analyses of the temporomandibular joint are
required and the standard projections (0°) are not opti-
mal, the projections can be adjusted with the angle pre-
selection.
The figure shows the directions in which the slice orien-
tation is swiveled with angle preselection.
NOTE
i
When you confirm the exposure with the R button, the
angle setting that was changed in the submenu line will
automatically be reset to the default setting 0°.
