[vtkusers] Question for relationship between ITK and VTK coordination system

Hello anyone,

I wonder how I can adjust ITK coordination to VTK coordination.
I got information from CT images and applied some algorithms to CT data
using ITK.
Using ITK functions, I could handle each pixels of the CT image (e.g., 512 x
512 pixel image).
And then I visualized the result using VTK. Also I visualized CT images
using VTK directly.
However, even I used same CT images, but the ITK result and VTK result were
different according to coordination.

So, what I'm asking is how I can transform ITK coordinate to VTK's one.
I tried to search this issues but I cannot find informative article.
Is there an mathematical relationship between ITK and VTK, or any function?
Please answer how to calculate or how to use functions for coordination.

Thank you very much.  

Best regards,
LEE
