HI,All

I’ve extracted the center line,and I don’t know the definition of tortuosity in 3D table.

I see a definition of tortuosity in the literature:Tortuosity was defined as L/D–1, where L is the length of the centre line from one point to another point, and D is the straight-line distance between these two points.I want to know the definition of tortuosity in the 3d slicer is the same as this one.

Thanks~!
