When you use :

	SetDirectoryName( "c:/yasser" )

then *every* single file in this particular dir (c:/yasser) will be
appended to the vtkDICOMImageReader. *Thus* if you need something that
has a meaning (for radiologist), you need to order that dir (c:/yasser)
that contains all your DICOM files, in order to subdivide this folder in
smaller ones. Where each one only contains, a particular study and a
particular (sub)serie (see DICOM standard for more info on :
http://medical.nema.org/)

	BTW, if you are sure you only have *one* serie (meaning the study is 
also the same), then you *don't* need to sort that directory.

[Then all you have to do is choose a *serie* dir (and not the top dir or
  the study dir).]

Does it makes sense ?
