HI! I have the same issue (trying to convert VTK files to NIFTI or DICOM). However the solution here doesn’t seem to work for me as I’m loading in a VTK file someone else made. Any solutions to how to convert these file formats without getting the same errors as above would be much appreciated! T…

VTK files can be anything (surface mesh, volume, volumetric mesh, etc). If it is a volume file, then load it into Slicer and in the Save data dialog, choose nifti file format. You can also use the DICOM module to export to DICOM format. If it is a surface mesh, you can import to into a segmentatio…

Hi Andras, I have this problem. I want to convert a .vtk file to .nrrd or .nifti file. I do following steps in slicer, but it doesn’t convert correctly. load data (that it dosen’t show anything) use segmentation module and import model , it make a segmentation node export as label map and save as…

As Andras noted, VTK files can specify meshes or they can specify volumes. They can be in a legacy format or a recent (but less popular) XML format. In the event that your VTK files are volumes in legacy format, you could convert them to NIfTI using the command line i2nii . Alternatively, you could …

[image] elahe_heydari: load data (that it dosen’t show anything) If nothing is shown then don’t even continue. Choose the correct content type (Volume for volume; Segmentation or Model for surface meshes) in “Add data” window in “Description” column.

Hi Chris_Rorden, I am actually working on a medical simulation in OpenFoam where the VTK file is obtained from Paraview. I wanted to show that into 3D Slicer for medical purpose. I saw this page and tried to go with the procedure given by you. With respect to this, I have installed i2nii and tried…

@ rasunag27 feel free to send me a google drive or dropbox link to my personal email (you can use Discourse to send me a message if you do not know my email). I should be able to extend my software to support ASCII. In general, when using a tool like Paraview to save data you should always choose t…

I would not recommend using .vtk file format for medical images. The limitation that instantly disqualifies this file format from serious use for medical imaging that it cannot store image axis directions (it always assumes image IJK axes are the same as patient LPS axes). Also, the format can only …

Generating dicom/nifti from vtk is easy. But this issue is how to match back to the original dicom where the vtk is made from.
