I just added

File::TypeOrientation( ) method
/**
* \brief  THERALYS' Algorithm to determine the most similar basic orientation
(Axial, Coronal, Sagital) of the image
* \note Should be run on the first gdcm::File of a 'coherent' Serie
* @return orientation code
*   #   0 :   Not Applicable (neither 0020,0037 Image Orientation Patient
*   #                         nor     0020,0032Image Position     found )
*   #   1 :   Axial
*   #  -1 :   Axial invert
*   #   2 :   Coronal
*   #  -2 :   Coronal invert
*   #   3 :   Sagital
*   #  -3 :   Sagital invert
*   #   4 :   Heart Axial
*   #  -4 :   Heart Axial invert
*   #   5 :   Heart Coronal
*   #  -5 :   Heart Coronal invert
*   #   6 :   Heart Sagital
*   #  -6 :   Heart Sagital invert

Maybe it can gives you the information you want.
