A few days ago, the 2020c edition of the DICOM standard has been made available on the NEMA server. Compared to the previous edition from March this year, 2 supplements and 20 correction items (CPs) have been incorporated. The standard text now consists of almost 7,000 pages (PDF version).
The supplements and a selection of the correction items are:

- CP 1993: OB-GYN Ultrasound code and template updates
The complete list of correction items incorporated and an overview of the changes to the existing 22 (20) parts of the DICOM standard can be found in the official release notes. Details on the changes from the previous edition are shown highlighted in the files with the word “changes” in the filename, which are also referenced on David Clunie’s “DICOM Standard Status” page.
As always, we have updated the DCMTK for the latest changes to the DICOM standard. That means, the data dictionary, the list of SOP Class and Transfer Syntax UIDs as well as the Directory Record Types are up-to-date, i.e. conform to the current status of the standard text. Also the Code definitions of the supported Coding Schemes and the supported Context Group classes from DICOM part 16 (Content Mapping Resource) have been updated (see DCMTK’s public git repository).
