[Insight-users] problem with Paraview + defomration field

[Kaveh Kohan]

Hi All,

I have a problem with interpreting deformation field shown by
paraview plus some questions and I would be thankful if anybody can
help.

- Does paraView only show .vtk files? I mean if I want to
overlay deformation field with anatomical image I have to convert
anatomical image to vtk format right? Is there any tool for that?

- I have tried paraview to visualize deformation field. Warped image (applying deformation field on moving image ) looks fine but when I view it in paraview using following this link:

location
if deformation does not look right! I have uploaded moving-image,
fixed-image, deformation field (in vtk and mhd/raw formats) in addition
to snapshot of what I see. To me, it is about 60 degree rotated:

(foo.tar.gz)

Since
the warped image looks fine, I think that my algorithm is working but I
have a problem with interpreting what I see in paraview. Perhaps, I am
missing something or doing something wrong in Paraview. I would be
thankful if you can help.

Regards,


ps: the foo.tar.gz file contains the following files:
defSimulatedImg_15.vtk:  deformation field in vtk format
defSimulatedImg_15.mhd/raw :  defromation field in raw/mhd format.
resSimulatedImg_15.mhd/raw :   warped images
SimulatedImg_15.mhd/raw : moving image
Template_1.mhd/mhd: fixed image
snapshot1.png :  snapshot of what I see in paraview.
