How do we get automatic measured maximal diameter?

After the segmentation of the aorta and centerline extraction, how can we get the maximal diameter of the aorta along the centerline curve automatically? is it available now in the 3D slicer?

Is the circular equivalent (CE) diameter means the maximal diameter at the cross-section?

You can get the maximum cross-sectional area in Cross-section analysis module in VMTK extension.

No, it is the diameter of the circle that had the same surface area that the cross-sectional area of the vessel.

Thanks for your reply.
