We added a completely new module that makes vessel (or airway or any other tree structure) centerline extraction much faster, flexible, and robust. It can quickly extract a network, determine branch endpoints automatically, allows editing of endpoints, computing centerlines, branches, and quantitati…

These should be doable. Can you describe with a bit more details and sketches or screenshots about what exactly you would like to show and measure? Create a new topic.

I followed this video step by step and got stuck at making the centerline. I was unable to select a surface input in the Extract Centerline module. I believe it has something to do with the endpoints and centerline curve shown at 1:02 . Can anyone care to explain what step I’m missing? I’m using 3d S…

I have been working on this module in the last couple of days. Please install the latest Slicer Preview Release (4.11.0-2020-06-30) and let me know if you run into any issues with this version.

I downloaded the 4.11.0-2020-07-04 preview release and now Extract Centerline is working as expected, thank you.

Dear Mr. Lasso, I would like to have tested the newest module with the newest 3D-Slicer version (4.11.0), unfortunately the program keeps crashing immediately after starting. I have reinstalled it several times and tested it on different computers (Windows 10). I hope you can help me. best regard…

Yes, sorry, today’s build is corrupted, it’ll be fixed by tomorrow. See more information and workaround here: [image] Issues running latest preview on macOS/Windows 10 Support Sure, you can access previous releases by specifying a date or number of days to go back. See de…

Thank you very much, I can now open the latest version of the 3D-Slicer (4.11.0), but I cannot load my CT-dataset with this version, although I do nothing else than with the stable version (4.10.2)

Use the DICOM module to import and then load the CT. If it does not work then post the details (how did you try to load the data, what error message is displayed, etc) in a new topic.

Excuse me, I have used this method to measure the vessel related morphology, and I feel it is very great. However, I have a question, does the radius measured here refer to the average radius of the vessel in this segment?

I had a quick look at the code and it seems the radius in the “Centerline properties” table is computed as the mean of the maximum inscribed sphere radii in the branch.
