[Insight-users] EncapsulateMetaData problem

[Luis Ibanez]

Hi Antoine,

Are you trying to manually edit the DICOM tag
describing the image spacing ?

If so,
ITK will not let you do that.

ITK uses the actual image spacing of the image
and writes it down in the DICOM tags.



    Regards,


       Luis
