Luca,
I dowloaded the dataset, and I don't get in which Serie is your 
problem nad/or haow to solve it automaticaly.

The Study, in directory ST1, is splitted into 12 directories SE1, ... 
SE12, each one has a single Serie (same Series Instance UID).

Series SE5, SE6, SE9, SE10 contain MIP images; each image has a 
different Orientation.
I guess you don't want to make a volume with them ;-)

Serie SE1 contains 'scout views' (3 Coronal images + 3 axial + 3 sagital)

Series SE2, SE3, SE4, SE7, SE8 are mono-incidence (no problem for 
you, I suppose)

In Serie SE11, all the images are Axial, but one that's Sagital
In Serie SE12, all Coronal + 1 Sagital
In Serie SE12, all Sagital + 1 axial

For the Series SE11, SE12, SE13, splitting them according to the 
Orientation would be usefull for you,
but would be stupid for Series holding MIP images....

I you think about something clever we could do ...

--> Tell me : in which Serie do you 'loose' images ?
(When I use
gdcmSerieViewer dirname=SE11
-just an example to show how to use vtkGdcmReader + gdcm::SerieHelper-
I can see *all* the images ).
