Hi, Giani.

All your images 'i009x.0000b.dcm' are Axial images, and s0000_0000b.dcm 
is a Coronal one, right?
but they *all* belong to
0020|000e [UI]                                                [Series 
Instance UID] [1.2.840.113619.2.55.1.1762902721.1885.1184133206.962]
(your imager decided so ! :-( )

Of course, this is not suitable for you, if you want to construct a volume.

You missed a part of the work :

After getting a 'Single Serie UID File Set', you have to split thid Fle 
Set into several 'XCoherent Filesets' (X for : Extra, sorry for the name 
...).
use :
XCoherentFileSetmap gdcmSerieHelper::SplitOnOrientation(FileList *fileSet);
It returns a std::map of FileList *.
In your case, you just have to ignore th Filelist with only onr image, 
and pass the other one to the vtkGdcmReader.

I think Luca Picello used this way of proceeding.

I tried to describe it, on
http://www.creatis.insa-lyon.fr/Public/Gdcm
--> User Guide

(a link to :
http://www.creatis.insa-lyon.fr/Public/Gdcm/HowToUseGdcm.html
]
but nobody reviewed the text.
Could you tell us if it's easyly understandable or not, that would be 
very usefull for us to enhance it.

Grazie.
