This is an outdated project. Go https://github.com/rbumm/SlicerLungCTAnalyzer for a package including the next development step with an excellent interactive lung mask segmenter.
This extension enables the easy and quick production of three frequently used masks from lung CT scans: A "Right Lung Mask", a "Left Lung Mask" and a "Trachea mask". This procedure is realized (semiautomatically) with 3D Slicer (1).
Usage:
- Start 3D Slicer (1) and load a lung CT volume.
- Start the "Lung Mask Generator" extension (what you see here, in "Chest Imaging Platform").
- Select the appropriate volume from the input drop down menu.
- Define multiple markers by using the predefined marker widgets from the UI: Place tem somewhere on the right lung, on the left lung, one in the middle of the trachea.
- Press "Apply".
- Check the masks, place additional markers if neede, press "Apply" again.
After some seconds you should have fairly exact right and left lung masks. Always check the boundaries.

Details
The script uses Slicer´s excellent "Segment Editor". Developed and tested with Slicer 4.11.20200930.
This extension is suited to prepare the masks for the CT Lung Analyzer (https://github.com/rbumm/SlicerCTLungAnalyzer) of the same author.
