Hi,

I am using Slicer v 5.4.0 and currently trying to compute:

1. cross-sectional area of a vessel
2. angle of bifurcation

I am using the cross-section analysis tool in VMTK but I am not sure if I am doing it correctly. I managed to generate the output table, but not sure which value is correct. Is there a video tutorial available?  
As for the angle of bifurcation, I am not sure where to start to approach this. Any help would be greatly appreciated!

Thanks
