[vtkusers] how to separate anatonomical parts

[ljhfdy4]

Hi, friends:

I'm actually using VTK for building anatomy pieces(cervical spine) from CT slices and export them in stl format. I want to seperate different vertebra and get closed volume of each vertebra for future solid modeling.

Now I can get the surface model of the spine, but the problem is all the vertebrae are connectecd to a whole part, no disk or space seperate them. I can't set different threshold as all vertebrae nearly have the same density.

I am wondering if anybody have some idea to seperate the spine into vertebrae. Meantime, I also want to know how to close the uppermost and lowermost surface of the model. I need a closed model instead of a model with two mouses opening on each sides.

Thanks a lot for attentation and further help.
