Hi Alyson,
welcome to the MITK users list!
You are right the axes should not be changed during the conversion. Have you
modified the extract slice filter (since the one you are using is named
ExtractSliceFilter2)?
We will try to have a look at this issue next Wednesday (on this day we all
take care of MITK bugs). Currently we are all busy with the ITK 4 migration so
I am not sure whether I we will find the time next week. But if I got it right
you currently have a workaround for this problem?
Feel free to file a bug at our bug tracking system: http://bugs.mitk.org/
Regards
Andreas

Subject: [mitk-users] Fwd: Dealing with mitk::ExtractSliceFilter
Hello,
I am a new user of mitk, and I am facing some issues while using the
VtkImageReslice for executing ExtractSliceFilter. And I hope that someone could
bring me some clues about how to solve it. I want to reslice a 3D MRI Image
with an origin and an orientation that I can choose. But my DICOM image appears
to be not so perfect for the ExtractSliceFilter. I noticed that the plane used
to define the WorldGeometry of the extracted slice is rotated after the
conversion to vtkImageData for the vtkImageReslice. So I define a vtkmatrix 4x4
with the transformation and I apply the reverse transformation to the plane, in
order that the plane can be in the right orientation after the mitk->vtk
conversion. But finally I can get a slice, but not at the position I want, and
the bounds are false, while they are defined with the bounds of the desired
slice.
Is there another way to solve this change of axes during the conversion?
Here is a part of the code

And I can the DICOM images as soon as I am asked to.
Thank you in advance
Regards
