Subject: Letter Ballot for Proposed DICOM Correction Package #100 (CPack-100)

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 (Cette adresse courriel est protégée contre les robots spammeurs. Vous devez activer le JavaScript pour la visualiser.). 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.

ATTENTION:
Please note that CP-1850 Change old RT-style SNOMED IDs to CT-style Concept IDs has been included in CPack-100.
Once again, we encourage you to vote and submit comments on this CP because it may have a significant impact on your implementations.
Please read the rationale section of the CP carefully.
We encourage commenters to perform risk assessments (an example is shown in the rationale) and communicate the results back to the Committee. The more detail you provide (specific codes, specific consequences) the better we will be able to help mitigate those risks.

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

CP# Title
1551 Resolve discrepancy in SOP Class multiplicity for ATNA messages
1552 Resolve discrepancy in defined Value Constraint for ATNA message
1766 Extend Original Attributes Sequence
1770 Add more compression information to X-Ray Radiation Dose SR

1841 Allow compressed RGB for WSI
1842 Referenced Frame Numbers used in Acquisition Context is limited by 16 bit VR
1843 JPEG-LS Planar Configuration constraints conflict with WSI, US, Enhanced Color MR and compressed RGB images
1844 Restore group length VR definition even though retired
1845 Add description and example for ROI distance measurements with coordinates
1846 Replace DCM code for circumscribed with SNOMED code
1847 Restrict future VRs to only upper case letters

1851 Add length of encapsulated document when not even
