For my project I’m working in 3D slicer.
I have made a segmentation of a dissected aorta. This segmentation contains a segmentation of the true lumen, false lumen and the both lumina combined.
In addition I have determine some anatomical planes, for example at the level of the bifurcation of the truncus pulmonalis. I have created this planes with the “Markups” module.

Now I want to determine the maximum diameter of the lumina at the intersection of the planes and the segmentations.
I have already tried to accomplish this with the help of the centerline and cross-section analysis modules of the VMTK toolkit. However, this modules does not allow me to determine the max diameter in the specific planes I have determined.

Do you guys know a way to obtain the intersection of a plane (created with Markups) and a segmentation, so I can perform measurement on that cross-section?

Cross-section analysis module can already compute the largest inscribed sphere diameter. You can show it if you click the “show” button for “Diameter (MIS)” in “Browse cross-sections”.

If you want to compute the largest diameter then you can click “show” for the “Cross-sectional area” row and then analyze the created “Cross section for …” model. For example, you can get all model points like this:
