[Insight-users] itk ResampleImageFilter + OutputDirection Problem (dicom)

[Luis Ibanez]

Hi Sebastien,

Thanks for sharing with us the resolution of the problem.

One last observation:

If the DICOM files are created properly, you shouldn't need
to use the OrientImageFilter at all.   ITK takes the direction
cosines directly from the DICOM headers (via GDCM), and
then uses those direction cosines during the registration
process.

In other words, you can directly register a Coronal image with
a Sagittal image without having to explicitly reorient any of them.

ITK image orientation now manages these direction cosines
properly (as of ITK 3.16).


    Regards,


          Luis
