Airway Analysis
This feature is available as a service (FaaS).
To create an airway segment:
Click Diagnose in the menu bar.
Click Airway 
.
Indicate two landmarks to create a box surrounding the region of interest. To adjust the box, click and drag one of the corner control points. To start over, click Reindicate landmarks 
.
Click Done. The airway is visualized.
The airway volume is shown in the 3D patient workspace together with the constriction point. In the reslice viewers the airway model is visualized as a yellow outline. In the 3D viewer you will see a colored volume. The color of the 3D object is dependent on the segmented volume for each plane perpendicular to the airway curvature.
Notes
On the Annotation tab of the smart panel, you can hide or show the airway model and the constriction point. To change the color of the constriction point, click 
and select Edit color.
When clipping the 3D model, all the objects except the airway model are clipped.
