Airway segmentation from CT in 1 minute using 3D Slicer

This is a short video tutorial of how to segment airways on CT using Fast Marching tool in 3D Slicer's Segment Editor module. Fast Marching is provided in "SegmentEditorExtraEffects" extension - install this extension before starting your segmentation. Note that 3D Slicer now has automated tools for lung and airways segmentation in the LungCTAnalyzer extension - for details see github.com/rbu...
3D Slicer is free, open-source software, can be downloaded at www.slicer.org.

Is this airway hollow inside or solid?

Segmentation is stores as a binary labelmap. It is automatically converted to a surface mesh for 3D display. You can generate volumetric mesh using Segment Mesher extension.

Great tutorial.Thanks for sharing it ¡¡

Liver segmentation in detail please

[@investigacionydesarrollo-p1384]

amazing tutorial! thanks ! it's not working for me though, the growing is too big, I follow the steps you mention in the video, but the model I get is way much larger than the ariway. Could you give me a hint? thanks so much for your help!

Why when I click on apply after initializing in the fast marching, the previewed segment disappears and I end up with an empty segment?

I can't seem to find the "Fast marching" effect in 3d Slicer 5.0.3. Any hints on where to find it ? I couldn't find it using the "Module Finder".

Fast Marching is provided in "SegmentEditorExtraEffects" extension - install this extension before starting your segmentation. Always check our video descriptions first - we try to answer all common questions there.

@@PerkLabResearch You are right, my bad, will be more diligent. I was able to segment the trachea (with a tracheostomy tube inserted) by painting seeds in three segments : AirOutsideBody, AirInTrachea and AirInLungs and then using the "Grow from seeds" tool to fill in. I couldn't get the "Fast Marching" tool to account for the entire cross-section of the trachea - it consistently rendered the trachea thinner than it actually was.
