[vtkusers] Extracting bone surfaces

[Carlos Delgado]

Hi all:

I am trying to extract the outer surface of CT bones and I have tried
some techniques, but they all failed. Also I looked at the vtk user
list for older messages concerning this topic, but it was not helpful.
The problem is that the bones have also a inner surface and it's hard
to isolate. Can anybody suggest me any method I can try to solve it?

Thanks so much in advance,
Carlos.
