Ortho Screen
Double-clicking the Sagittal View on the Preview Screen displays
the Ortho (Ceph) Screen.
The Ortho screen displays the Lateral Cephs in Radiographic and
MIP mode as well as a Coronal View in MIP mode, all at the
thickness of the volume. The last image is a Mid Sagittal Slice at
20mm thick.
Right-clicking the blank view at the bottom right of the Ortho screen
displays a single item popup menu. Clicking
Tag Airways generates
a 3D view of the airways for the patient in the blank view. In
addition, the tagged airway data is displayed in the view at the
bottom center of the Ortho screen.
The graph is a vertical x/y plot. The vertical axis is the slice position,
and the curve itself shows the open airway volume at the slice
locations of the vertical extent axis. The further the curve extends to
the left the larger the air slice volume. If the curve has a kink to the
right or extends close to the vertical base line, that would indicate an
airway restriction.
