I want to measure the upper airway (oropharynx) but I don’t know how to measure. How to calculate the airway length and volume from 3D slicer.
To calculate the volume you will need to segment it first, you can find many tutorials online, then you use Segmentstatistics module to get the volume of your segment.
As for the lenght if it’s linear use the ruler tool and if it’s a curve use the curve tool (available in the Nightly version and use this script to get its lenght in mm (after renaming the curve adequately):
curve = getNode("MarkupsCurve") curve.GetCurveLengthWorld()
