Extraction of artery radius along the centerline

Support
1

Hi everyone,

I realized a segmentation of the femoral artery and used Extract Centerline to obtain the coordinates of the centerline. The data extracted from this centerline gives a radius (I guess an average one) of the complete artery.
I would like to be able to know the radius of the arteries at any point of my centerline, how can I do that?
I extracted the position of each point defining the centerline but cannot find how to obtain the radius for each of this point.

Thank you !

If you output the extracted centerline as a model then radius is available as point data. See Examples section of VMTK extension documentation for details.
