Preliminary Events

Kees Verduin opened the meeting and welcomed the delegates. A quorum was present.

The chair offered a special welcome to Mike Partridge of Hitachi, who would like to participate in WG-16. Since Hitachi is not a DICOM member, it cannot automatically become a member of WG-16. Therefore, members recommended that the DSC appoint Hitachi Medical Systems as member of WG-16. (AP 20-0, KV)

    The following agenda was offered and approved:

  1. Review list of action items

  2. Discuss outstanding CPs (CP 253 done, no objections)

  3. Discuss membership roster (by HC)

  4. Discuss outcome of the SPIE workshop

  5. Discuss outcome of the testing day

  6. Create CPs related to the above

  7. Identify future work items

  8. Set date of future meetings

  1. Action Items:

    1. There were no current, outstanding action items.

    2. One item was identified for future action – c-extract frame proposal. Members believe that this function is urgently needed. It could be an issue for the Joint DICOM/ISO TC 215 WG (Nick Brown and Hidenori Shinoda co-chairs). Members requested that Howard Clark bring this to the attention of the DSC.

  2. Outstanding CPs,

    1. CP353: full support.

    2. CPXXX (Cardiac and Bulk Synchronization): full support.

    3. Issues raised by David Clunie (windows level/width description): Members will support a CP on this when required; but, MR currently has no use case for multiple window settings.

    4. Other issues: no use case for acquisition context found yet.

  3. Membership Roster

Mark Day and Luigi Pampana are mailing members only. Kees Verduin will ask Mark Day how he wants to participate in future.

  1. Outcome of the SPIE Workshop:

    1. Dale Seegmiller of DR Systems and other attendees identified an issue regarding compression (AP 20-2).

    2. Members believe that more promotion is needed. Kees Verduin’s lecture is the only related item on the agenda at CARS conference in June. One idea is to create a specific web site for participants with updates, FAQ's, etc. This will be discussed in a Tcon with Charles Parisot (AP 20-3).

  2. Outcome of the Testing Day

Members prepared a report for David Clunie and funding participants as well as for other WG-16 members and testers.

  1. Create CPs related to the above

    1. No particular CPs (relating to the MR part of the supplement) are needed.

    2. Members will seek guidance from David Clunie on how to proceed with CPs related to the 2003 standard as a whole.

  2. Future Work items

The white paper requirements were moved to action item 20-1. This paper was regarded as very useful (by all) and urgently required by most (ES, MP, BH, KV).

  1. Next Meeting and Teleconferences

No face-to-face meetings have been planned. Ad-hoc meetings will be scheduled when required.

  1. Adjournment

The meeting of WG 16 adjourned on Thursday, February 20 at 12:30 PM.
