Hi, Gianni.

Right now, nothing is done.
-> How many images are there (recursively) in the directory?
-> On what criterion would you like to restrict the studies from being 
loaded?

They is a  method
gdcm::SerieHelper::AddRestriction(uint16_t group, uint16_t elem, 
std::string const &value, int op);
that allows you to ask for dropping images that don't match to a given 
criterion on a given tag
for instance images where modality IS NOT "CT", or where date is < 
"01-01-2007",  or where patient name is not "Lazzarato Dr.Gianni", etc.
(restriction criterions are 'added' if gdcm::SerieHelper::AddRestriction 
method is called more than once)

They are not taken into account at loading time, but it shouldn't be 
very difficult (/ should be usefull ?)  to add the feature.
Would it solve your problem?
