There are a couple of examples that I have found valuable:

1. LiverTumerSegmentation example in InsightApplications.
2. vtkINRIA3D (sadly the svn/git access is not publicly available at the moment)
3. The vtk wiki
4. paraview

For my DICOM viewing projects I am using the vtkINRIA3D code modified
for my usage.
