Sources for dicom public dictionaries: * the official source is the part 6 of the dicom standard (see http://www.dclunie.com/dicom-status/status.html#BaseStandard2001). * http://www.fpimage.com/Manuals/Imp/dicomdic.html an html group based presentation. * ftp://rsbweb.nih.gov/pub/nih-image/documents/dicom-dict.txt a C syntax oriented version provided by NIH (Jim Nash) * http://afni.nimh.nih.gov/afni/AFNI_Dist/afni_src.tgz extract mri_dicom_hdr.c (tar zxvf afni_src.tgz afni_src/mri_dicom_hdr.c) and look for the definitions of CMD_dictionary, META_dictionary, ID_dictionary, PAT_dictionary... * Actually, the *official* Dicom Data Dictionary is on http://medical.nema.org/dicom/2003/03_06PU.pdf (check it every year, some tags are added, some names change) All C syntax oriented stuff, or anything else -but gdcm one- you can find on the net is very partial. WARNING : The Dicom Tag is an identifier inside the Dicom Dictionary, The Tag Name *is not* Comment on the file NIH.dic, you can find the following discussion on comp.protocol.dicom(*). As clearly specify by David Clunie all thoses tags are extremely dangerous to use since they override some other, we are only adding them to gdcm to be able to read /apparently/ some NIH images.

None of these should ever be used. ...
