- * \brief AVOID using the following fourth field at all costs.
- *
- * They are at least two good reasons for NOT using fourth:
- * - the main reason is that it is NOT part of the 'official'
- * Dicom Dictionnary.
- * - a second reason is that it is not defined for all the groups.
- * .
- * Still it provides some semantics as group name abbreviation that
- * can prove of some help when organizing things in an interface.
- * For the time being we keep it in gdcm but it migth be removed in
- * future releases it proves to be source of confusion.
- * Here is a small dictionary we encountered in "nature":
- * - CMD Command
- * - META Meta Information
- * - DIR Directory
- * - ID ???
- * - PAT Patient
- * - ACQ Acquisition
- * - REL Related
- * - IMG Image
- * - SDY Study
- * - VIS Visit
- * - WAV Waveform
- * - PRC ???
- * - DEV Device
- * - NMI Nuclear Medicine
- * - MED ???
- * - BFS Basic Film Session
- * - BFB Basic Film Box
- * - BIB Basic Image Box
- * - BAB
- * - IOB
- * - PJ
- * - PRINTER
- * - RT Radio Therapy
- * - DVH
- * - SSET
- * - RES Results
- * - CRV Curve
- * - OLY Overlays
- * - PXL Pixels
- * - DL Delimiters
- * .
- *
- * Other usefull abreviations used for Radiographic view associated with
- * Patient Position (0018,5100):
- * - AP = Anterior/Posterior
- * - PA = Posterior/Anterior
- * - LL = Left Lateral
- * - RL = Right Lateral
- * - RLD = Right Lateral Decubitus
