DICOM WG10: Strategic Advisory Committee

1
DICOM WG10Strategic Advisory Committee

• Report to DSC meeting
• June 25, 2002, Paris

2

• WG10 meeting June 24, 2002, Paris.
• DICOM Strategic Document
• Proposal to change the approval and internet
  distribution Strategic Document updated and put
  on the internet immediately after submission by
  WGs and approval in DSC (shall always include
  strategic section of WG).
• Relation to other SDOs and related groups
• ANSI X12N, ASTM E07.11, HL7, IHE, JPEGNo news
• Status of translations of DICOM codes no
  progress this time

3

• DICOM becoming an ISO standard
• Wait for the outcome of the decision process in
  ISO for HL7 becoming an ISO standard ( fast-track
  or pilot process).
• ISO will take a decision in the August meeting in
  Melbourne.
• WG10 will devise a course of action in the
  September meeting, based on the ISO results.
• In the meantime we propose a joint workitem, and
  in the development we want to try-out the process
  of working together with ISO/WG2 on a workitem.

4

• Web based reference to DICOMs permanent objects
  ( URL)
• Workitem proposal finished, for approval in DSC
• submitted to ISO to be approved in the August
  meeting of ISO TC 215
• will be a test case for a formal working together
  between DICOM and ISO on the creation of a
  supplement to the DICOM standard, and approved as
  ISO standard.
• MPEG the Visible Light Working Group
• WG10 supports the approach proposed by the group

5

• Unicode, Objectives/Requirements
• Full-fidelity, single language pipeline, with
  different presentations
• Ensure Q/R SCP that has persistent objects, can
  serve SCU with different capabilities
• Create multi-lingual archives, multi-lingual
  pipeline simultaneously.
• WG6 will explore these requirement for Unicode in
  DICOM

6

• DICOM standard in XML, objectives
• Consistency of the DICOM Standard, when adding
  supplements or CPs
• Publishing Standard multiple formats PDF, Word,
  ..
• Maintain/edit/extend standard easier
• Improve efficiency and consistency of
  implementations, test tools, DICOM toolkits.
  Probably more for test tools, implementations
  need more context.
• More powerful means for information model, SOP
  Class specification.

7

• DICOM standard publication and maintenance in
  XML, action
• All members, assess in the companies if there is
  a real interest to allocate resources to this
  topic. For instance, a special publishing WG
  could be established.
• This group could first look at the both the
  technical and organizational issues of
  maintaining the standard in XML.

8
Strategic planning process

• We had a closer look at the following main
  topics
• Image distribution all over the world
• Workflow management
• Structured reporting objects and templates
• New imaging technology
• Quite a number of topics were identified, and in
  the September meeting we will discuss about the
  priority of each topic.
• Also identified the need to communicate about our
  Strategic Plan topic, at RSNA and in the joint
  meeting with ISO.

9

• Topics in Acquisition domain
• Workflow outside the Radiology domain RT, VL,
  Cardio. Requires specialized workflow. Refreshing
  the worklist, event based.
• Amount of data generated, kind of data generated.
• More, 3D, real-time, grayscale, color,
  time-sequence, text
• Text really broadens the scope evidence
  documents, key image note, codes, vocabularies,
  templates. Need for simple, small documents, e.g.
  just a few measurements
• Amount of data will impact performance
• Need to manage separate objects that do belong
  together, SOP Class future. modeling instead of
  SOP ( HL7 way), separate info model from
  communication

10

• Topics in Acquisition domain
• Integration, data from multiple modalities needed
  together, fused, merge recipe. Requires
  synchronization in time and/or space.
• US CathLab
• PET CT
• MR NM
• Communication technology
• Media for exchange, profiles
• wireless (TCP/IP is on top of this, should be no
  issue)

11

• Topics in Post-processing domain
• Presentation, have only grayscale presentation
  currently.
• color, 3D, waveform, Cine, MR-multiframe
• hanging protocols
• multi-modality presentation
• SR presentation
• Interactive collaboration, tele-radiology
• Data mining, statistics, need for uniform
  definition.
• Should we organize a workshop on this topic?

12

• Topics in Archive domain
• Delete service. All images come together in
  central archive with satellites. Co-operation in
  a loosely connected environment.
• Co-operation between multiple loosely connected
  workflow managers.

13

• Topics in Reporting domain
• Harmonization with CDA L3, XML encoding
• Next versions of TID 2000, templates
• Codes, Vocabulary, Procedure Codes, Diagnostic
  Codes, HIPAA induced codes

14

• Topics in Result Distribution domain
• Persistent Object Reference
• Exchange information outside the DICOM domain
• HIPAA, Privacy, Security, Authentication, VPN
• CD/DVD for exchange
• from PACS site to non-PACS site
• multiple objects, reports, images, compressed
  images
• DICOM CD must be readable by all DICOM devices
• Communicate to referring physician without PACS
  or specific tools, replace film
• legal requirement in some countries give all
  images to patient

15

• Topics in Treatment/Treatment planning domain
• CAD tools, HPGL standard, templates for implants
• 3D, image guided surgery, contours, locate images
  in 3D space
• multi modality aspect
• Image fusion
