I need a perpendicular cross sectional area along centerline in vessel segmentation model.

I can extract centerline using VMTK extension and get diameter along centerline using centerline metrics extension.

However, I don’t know how to automatically measure the perpendicular cross sectional area’s’ along extracted centerline.

It will be very useful to determine the appropriate stent size in stenotic curved vassel.
