Next call is March 11, 2020

• F2F planning: REMEMBER TO RESPOND TO RSVP POLL
  • Day 1: Introductions and call with DICOM WG 26 re: Digital Pathology (DPIA)
  • Day 2: TMA and transfusion medicine profiles, SET, Digital Pathology
  • Day 3: SET and Wrap up
• Digital Pathology:
  • Reviewing the comments on the DPIA
  • Issue log is missing comments from Nicholas Jones which were received yesterday
  • Line 195 = Open Issue 14A
    • Arranging image order - sort order should not be determined in the header of the image – DICOM has different ways to specify the sort order, it is not done at this point in the workflow – so should not be done here; metadata needed for sort order determination
    • In practice we are sorting on the default order of the case work (based on the barcode label)
    • Will remove the mention of “sort order” but leave the issue open because of the diagram.
      • Unclear if this diagram is the DICOM model, if it is accurate etc. and how the gross images fit in
      • Think this is helpful to understand the arrangement
      • Leave it as open issue, remove mention of sort order, reword the open issue that this model still can be adjusted
      • Divorce the model from the sort order question
      • Mention of word Procedure Step in DICOM has specific meaning – the diagram has a mix of defining the physical abstractions and different workflow steps that create images are all called procedure Steps – this is a confusing term (in other IHE profiles it refers to how a sample is processed, rather than a workflow step) – Nick will work on this diagram going forward
  • Line 205 – Mapping to specimen DAM
    • We did not include the mapping in the appendix – we need to update the text if we don’t include the mapping to the DAM – ideally, we should add the mapping to Vol 2 – add mapping back in.
  • Line 425
    • Sending to different image manger/archive for some instances when something is not working
      • Images can be stored, but that does not mean the images are going to be available for review by pathology = what status message means – what the status means
        • Could be ready for QA review, but not for pathology review, but it is still stored
          • We used to have transactions to query asset availability
        • Do we want to include all these details in this first pass of the profile, or should we keep that out?
        • We may want to add disclaimer: status change to manager does not imply that the image is available right away
      • We need the downstream system to know there are x imaging procedures to be done and x of those are now ready for pathologist review – not clear which actor has that responsibility
        • Could be the image display or the acquisition manager or the LIMS
        • Providing instance availability message from image archive to whoever is the manager of the workflow – that is how it is done in radiology
  • Line 510 in Glossary
    • Digital image asset – replace “versions” with “representations”
    • What is the digital representations of non-physical asset – like graphs, histograms etc –
      • There is no formal DICOM term – use instance
  • Agree with the updates to the other glossary terms
  • Storage MUST be required, do we make storage commitment required, too?
    • Device MUST have functionality of storing images
    • When you have storage commitment then modality can wipe out the images that have storage commitment
      • Other portions of the workflow depend on the completion of this – this supports asynchronous workflow
      • Need to fix up LAB-82 that should not create issues with the asynchronous workflow
    • Decision: make RAD-8 and RAD-10 Required for now (if in testing this creates issues for RAD-10, then we can revisit)
  • Line 610-611
    • Accept rewording
  • Another comment from David Clunie: Referencing the web
    • DICOM WG26 - Connectathon used retrieve rendered – clone the DICOM transactions and include the retrieve rendered transactions into a lab profile
  • CAP will post a doodle poll to continue review of the comments for another 1 hour picking up after the 610:
    • Dan, Nick, Mandel, David, Raj at least
• SET update:
  • Latest version was sent to group with open comments only
  • Requested biobank experts to read and make comments on re-ID section
  • Need to still review the message structure – will do that at F2F at the latest
• New proposal:
  • Map APSR to FHIR resources
    • Gunter knows German vendors that are interested in that, since this will be mandated by the universities
    • Timeline is for publication by end of 2020
    • Motion to approve this project
      • Riki, Gunter,
      • Riki will make announcement to OO and SD
      • Will set up project calls if needed
      • Need to define the scope – if this includes workflow or not
• CP-264 https://wiki.ihe.net/index.php/PaLM_Technical_Committee#Change_Proposals
  • Non mutually exclusive interpretation codes
  • This is also the case in V2 and in FHIR
  • Link to the code system: http://build.fhir.org/valueset-observation-interpretation.html
  • Updated the CP with some of this text
    • Motion to accept updated CP: Riki Merrick, Dan Rutz; no further discussion; Against: 0, abstain: 0, In Favor: 11
• Discussion in prior WGs about how to represent FHIR to represent lab orders and lab results is not well documented
  • HL7 is doing some work in this space – Ralf and Riki will collect the details of ongoing work and send to PaLM listserve

Call adjourned 10:21 AM EASTERN
