[Insight-users] ITK to VTK Convertion Error

[Luis Ibanez]

Hi Abayiz,


Can you describe the distortion ?

Maybe post a screenshot ?

Note that VTK images do not have
a explicit representation of Orientation,
so the information about the DICOM
direction matrix gets lost when you use
VTK for reading the DICOM images.

You may find better to use the ITK GDCM
reader in order to load the DICOM images.
