[Insight-users] ITK to VTK Convertion Error

[Abayiz]

Hi Luis,

Thank you very much for your answer. 

The problem is, if I use VTK to load dicom, and view it also using VTK, everything is fine. But after I converted it to ITK, then the sequence problem comes.  after conversion from VTK to ITK, the dicom slices are totally not in the correct sequence. Any suggestions? 

Thanks again. 

Abayiz
