[Insight-users] Bug in DICOM reader for 4D data?

[Matthias Schabel]

As per Luis' suggestion in a previous (fairly old) post (here :  
http://public.kitware.com/pipermail/insight-users/2004-May/008568.html),
I am attempting to get ITK to correctly read a 4D (time+volumetric)  
dynamic MRI data set. With filenames ordered following the suggested
grouping (chunked first by acquisition time, then by slice), when I  
attempt to read, I end up with a 1 x 1620 x 192 x 176 volume. While
the total number of voxels is correct, this should in fact be a 90 x  
18 x 192 x 176 volume. I have already verified independently that
the time stamps are identical for all slices for each acquisition, so  
this seems to me to be a bug in the DICOM reader. I really would prefer
to have the data in the form of a single 4D volume rather than a  
vector of 3D slices - any suggestions/workarounds?

Thanks,

Matthias
