I had a look a Xmedcon's code a few years ago.
I gave it up, since they use :
Patient Orientation (0020,0020),  (Optional Tag for MR, CT,, etc)
and the suppose the only values for cosines inside "Image Orientation 
(Patient)" (0020,0037) are -1, 0, +1 !

Have a look  at :
http://www.dclunie.com/medical-image-faq/html/part2.html#DICOMOrientation

It *computes* the "Patient Orientation" from "Image Orientation 
(Patient)" ...

gdcm uses David Clunie's code in the method :
std::string Orientation::GetOrientation ( File *f )
