DICOM 2014b

Last week, after another meeting of the Working Group 6 (WG-06), the 2014b edition of the DICOM standard has been made available on the NEMA server. Compared to the previous edition from July this year, 1 supplement and 10 correction items (CPs) have been incorporated.

This new edition of the standard also introduced a new value representation (VR) for Universal Resource Identifiers (URI) and Universal Resource Locators (URL), so we have taken the opportunity to enhance the current development version of the DCMTK accordingly. The new value representation “UR” is used for a couple of existing DICOM attributes that were previously mapped to “ST” or “UT” (see CP-1324 for details). Apart from this, only 4 new DICOM attributes have been added to the data dictionary compared to the previous edition. Of course, we have again updated the “dicom.dic” file that is used by the DCMTK library and tools.

New SOP Classes, Transfer Syntaxes or Directory Record Types (DICOMDIR) were not introduced this time, so there was no need to update other parts of the DICOM toolkit.
