DICOM 2019e

A few days ago, the 2019e edition of the DICOM standard has been made available on the NEMA server. Compared to the previous edition from September this year, 0 supplements and 27 correction items (CPs) have been incorporated. The standard text now consists of more than 6,800 pages (PDF version).

A selection of the correction items are:

  • CP 1726: Add clarification note that C-FIND SCP should ignore unknown standard and private tags​
  • CP-1777: Derivation of Photometric Interpretation in STOW-RS​
  • CP-1867: Add codes for AI visual explanation maps​
  • CP-1893: Fix inconsistent Relationship Content Constraints (SR IODs from Supplement 164)​
  • CP-1895: Add presentation address to file meta information for DULP and Web Services​
  • CP-1899: Number of Frames attribute should never have a value of zero​
  • CP-1901: Return in query response what Transfer Syntax is available for retrieval​
  • CP-1902: Some IODs that need it are missing the Synchronization Module​
  • CP-1913: Coding Scheme Version requires Coding Scheme Designator to be present​

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 again up-to-date, i.e. conform to the current status of the standard text; with one exception: support for Supplement 202 (Real-Time Video) is still somewhat incomplete (see DCMTK issue #898). But the Code definitions of the supported Coding Schemes and the supported Context Group classes from DICOM part 16 (Content Mapping Resource) have already been updated.
