Hello!Friends!  
I am trying to measure the max curvature of the part of aorta.Why the max curvature in the Tree centerline curve and the Network curve is so different?Which is accurate?  
Is there a way to make the centerline smoother?Because i think the curve is not very smooth,there are some hard turns on the curve,so that the curvature is not accurate.The curvature i measured was much larger than that in the paper.

Pic 1 is a 3D image reconstructed with a manually Region of Interest  
Pic 2 is the Network curve and it’s max curvature  
Pic 3 is the Tree centerline curve and it’s max curvature  
THANKS!!!
