[vtkusers] vtkDICOMImageReader -> vtkCutter -> vtkMarchingCubes

[superzz]

Hello Jinyoung Hwang
Thank you for your example. But the data is passed as reader -> vtkCutter ->
vtkMarchingCubes your example, not as vtkDICOMImageReader -> vtkCutter ->
vtkMarchingCubes as I requested.

May you take a look at it again?

Thanks

superZZ
