Dear DI Community,

Please see below request from DICOM regarding DICOM Ballot CPack-102. Please submit your responses by July 5, 2019 so I can vote on your behalf. If I don't receive any feedback by the deadline, Canada will abstain.



To: Voting and Alternate Voting Representatives of the DICOM Standard Committee
From: DICOM Secretariat: Luiza Kowalczyk, Senior Operations, DICOM Manager and Lisa Spellman, General DICOM Secretary
Subject: Letter Ballot for Proposed DICOM Correction Package #102 (CPack-102)


Following is a letter ballot seeking DICOM Standard Committee approval of proposed DICOM Correction Proposals (CPs).
Note: only the officially designated voting representatives (or alternates) of the Members of the DICOM Standards Committee (See list.) are invited and entitled to cast a ballot.
Others in the DICOM Community receive a copy of this ballot as a courtesy so that all will be apprised of anticipated revisions or extensions to the DICOM Standard.

The DICOM Standard, which addresses image communication and related data management functions, was first published in 1993. DICOM Working Group Six regularly reviews and approves extensions (Supplements), clarifications and error fixes (Correction Proposals) to the Standard. Requests for such fixes or clarifications or general questions and comments may be submitted by anyone to the Secretariat (This email address is being protected from spambots. You need JavaScript enabled to view it.). CPs are batched into C-Packs for balloting to the DICOM Standard Committee members. Approved corrections are incorporated into the next edition of the DICOM Standard, which is now released 5 times a year, following each WG-06 meeting.
Correction Proposals may address:
• Ambiguities – standard text that is not precise or leads to various interpretations.
• Clarifications – to facilitate the interpretation of the Standard but not change the spec
• Errata – correction of normative and informative errors.
• Inconsistencies – sections of the Standard that contain conflicting definitions.
• Omissions – Obvious text was not included in the Standard.

The following Correction Proposals, approved by WG-06, are included in this ballot:

CP# Title
1808 Update DICOM to reflect changes in IHTSDO SNOMED CT-DICOM Subset for JUL 2018 and JAN 2019 INT Release
1865 Concept Codes for use of UPS in RT Treatment Sessions

1882 Handling of private attributes in C-FIND and QIDO-RS
1883 Retire DCM code for Digital Mammography and replace with LOINC code

Each proposal specifies the type of correction, the rationale for the correction, the sections of the DICOM Standard that will be changed, and the correction wording. In voting, you may vote on the complete package or vote on the individual Correction Proposals.
