Dear all,  
I have the same problem as in this post:  
[http://itk-users.7.n7.nabble.com/ITK-users-ResampleDICOM-example-and-DCMTK-td34473.html](http://itk-users.7.n7.nabble.com/ITK-users-ResampleDICOM-example-and-DCMTK-td34473.html)  
in short, no output.  
The problem started when I tried to load large micro CT (13GB) to 3D Slicer. Slicer reported default spacing and origin [1,1,1] and [0,0,0].  
I tried to use ITK directly but I got the same error. I found the above post so I used it. The good news, DCMTK report correct spacing and origin. The bad news, when I do resampling, I got the same error in the post, no output.  
I did a work around by saving the dicom to nrrd file then use Slicer to produce a dicom again when needed but it would be nice if the code above works.  
Best!  
Ibraheem

Hi Ibraheem,

In the latest Slicer Nightly, it can optionally use ITK with a DCMTK backend instead of ITK with a GDCM backend, which should be helpful in your case.

HTH,
