WG6 maintains the overall consistence of the DICOM standard. It provides technical guidance to all DICOM working groups and serves as the technical coordination point. It also develops extensions (Supplements) to DICOM typically related to overall systems enhancements. Some of the responsibilities include:

  • Executing the DICOM Maintenance Process (Correction Proposals). The process is used to make “corrections and minor changes” to the current versions of the Standard. Any corrections made are processed using the normal Letter Ballot procedures as defined by NEMA.
  • Provision of technical coordination and guidance for all WGs. This includes review and official approval before the Public Comment, Letter Ballot, and Final Text draft releases of all supplements.
  • Development of Supplements to the standard related to Print, Image Management, Workflow Management, etc.
  • Tracking the progress of workitems and supplement and report stalled items (no activity over a period of three years) to the DICOM Standards Committee.
  • Coordination of joint development efforts with ASTM (DICOS), ISO and JIRA.
  • Coordination with MITA for the publication of DICOM.
