[Insight-users] Unexplained file extensions in ITK

[Luis Ibanez]

Hi Reuben,


                     Welcome to ITK !!


I'm not aware of any fileformat that uses the extensions:

       ".t1"
       ".t2"
       ".pb"

It is tempting to especulate that they simply refer to
MRI modalites "T1", "T2" and "Proton Density".



If the files actually contain DICOM files, then you
should be able to read them directly with the ITK
ImageFileReader, since the DICOM reader doesn't expect
any file name extension in particular.

I would suggest you try reading one of the 2D slices
with the example:

      Insight/Examples/IO/ImageReadWrite.cxx

with a command line similar to:

      ImageReadWrite   input.t1  output.mhd


and then visualize the output with

      Slicer (www.slicer.org)
      ParaView (www.paraview.org)


Actually, you may be able to read the .t1, .t2, .pd
files directly with Slicer, since Slicer uses the
ITK readers.


Also, you could use the Example:

        DicomImageReadPrintTags.cxx

just to check if there are actual DICOM tags in
these files.



Please let us know if you find any problem,


     Thanks


        Luis
