11 * \defgroup gdcmHeader
13 * The purpose of an instance of gdcmHeader is to act as a container of
14 * all the DICOM elements and their corresponding values (and
15 * additionaly the corresponding DICOM dictionary entry) of the header
18 * The typical usage of instances of class gdcmHeader is to classify a set of
19 * dicom files according to header information e.g. to create a file hierarchy
20 * reflecting the Patient/Study/Serie informations, or extracting a given
21 * SerieId. Accessing the content (image[s] or volume[s]) is beyond the
22 * functionality of this class and belongs to gdmcFile.
23 * \note The various entries of the explicit value representation (VR) shall
24 * be managed within a dictionary which is shared by all gdcmHeader
26 * \note The gdcmHeader::Set*Tag* family members cannot be defined as
27 * protected due to Swig limitations for as Has_a dependency between
28 * gdcmFile and gdcmHeader.
