[ITK] [ITK-users] Read 4D CT cardiac dicom series and save it as a single 4D nifti file

[Andras Lasso]

3D Slicer can load some 4D CTs a 3D+t sequence and you cab save it as a 4D nrrd. You may give it a try. If it doesn't work for your sequence then report the problem on the slicer-users mailing list. If you can provide a sample data set then slicer developers most likely will be able to make it work.

Hi there,

Thanks for the suggestions. VV is not really an option since I have to analyze many cases. I even tried to use VV but it gives me the wrong order of the slices.

I am trying the  "itk::ImageSeriesReader" (right?) but it is complaining that "Position is not unique".  I think it refers to the fact that the slices in my "series" have the "same location". Not sure this is meant to transform 2D into 4D if it expects different locations, maybe it is for 2D into 3D. Any idea?

Regards

You can do it pretty easily:

Read DICOM using SeriesFileReader and then connect output to a FileWriter with the file name of your choice (in this case, it would be "output.nii.gz").

Dear Marco,

Actually I do not know how to do it in the ITK but for such cases (if it is
few cases) I normally use "VV: the 4D slicer". You can find it in the
following link:

I hope this will be of some use.
