Operating system: windows  
Slicer version: 4.11  
Expected behavior:  
Actual behavior:  
I had done segmentation of vessel and extract centerline with VMTK tool kit  
With centerline metrics, i was able to get diameter of vessel along centerline  
(Radius of inscribed sphere). However, clinically, when clinicians plans to do stent insertion, we need to know cross sectional area along to centerline to determine the size of stent.  
I have trouble with calculate the cross sectional area perpendicular to center line  
Is there any way to automatically calculate perpendicular cross sectional area along centerline ?
