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…

Hello to the community, how are the “Curvature, Torsion, Tortuosity and StartPointPosition” defined in the “Extract Centerline” module? Which formula is the basis for the measured values? Unfortunately, I have not found this in my research. Greetings Tamu

These are all computed by VMTK library. You can find detailed description of all the algorithms in Luca Antiga’s PhD thesis .

Hi, it seems that “Extract Centerline” has many more options than “Centerline Computation”. Is there a new/updated video available somewhere, presenting the functionalities, and a minimal use-case of the “Extract Centerline” module? I found only a video where “Centerline Computation” is used: Vessel…

[image] mikbuch: Is there a new/updated video available somewhere Yes, there is this good video showing the workflow which works fine: [New vessel branch extraction module for 3D Slicer]

Thank you Rudolf. I followed the video and everything worked for my segment. :+1:

Hi! I would like to use the vmtk library to extract centerline of airways. When I install the extension through the wizard, everything seems fine: [2022-11-11] However, when I try to actualy use the module, the following happens: [2022-11-11 (1)] If I double-click the name of the extension, no…

[image] Peter_Horvath: Same for the curve centerline extraction module. As for “Curve centerline extraction” module, it is a helper module, that combines and automates a segmentation process relative to an arbitrary curve, followed optionally by centerline extraction. It has a dependency on …

Thank you, my bad. Centerline extraction works fine, and that is what I need.

Set one point at the top of the trachea and autgenerate the others. [image] Relatively easy
