[vtkusers] Encapsulating VTK files in DICOM

[Mathieu Malaterre]

David,

	Just to make sure we are speaking of the same thing, you are refering 
to the XML-based VTK file format as describe online at:

	http://vtk.org/pdf/file-formats.pdf

	What exactly are you looking for ? XML-VTK file can support dataset of 
type: ImageData, StructuredGrid, PolyData, UnstructuredGrid ... So the 
question would be for ImageData type, should we respect let say Imager 
Pixel Spacing ? Then in the case of an UnstructuredGrid, how can the 
DICOM file describe the number of cells, a new DICOM tag ?

My 2 cents,
Mathieu
