1.        Opening

1.1.      The conference was called to order at 2:00 p.m. US ET.

1.2.      The antitrust rules were reviewed, and DICOM patent policy as well.

1.3.      The agenda was approved.

1.4.    Approval of the minutes from June 26thwere postponed for the next call.

2.        Discussion of incorporating AI into workflows using standards

Workflow 1: Passing Discrete Data in the Reading Workflow

A radiologist opens a study for a Head CT. An AI algorithm runs to detect the presence of a midline shift and the measurement of the shift. This information is passed to the PACS and the reporting system. Using the PACS and reporting system the user finishes the study and signs the report. The discrete midline shift measurements along with the report are sent to the patient records.

Workflow 2: Passing Discrete Data in the Image Generation Workflow

A patient has a chest x-ray performed, after the chest x-ray is performed, an AI algorithm runs to detect a pneumothorax. The discrete pneumothorax is sent to the worklist for prioritization and to the PACS for storage.

Brainstorming questions/thoughts:

  • What if things don’t go as planned? 
  • How are we getting images to Al algorithms?
  • What are we using for tracking?
  • What is the benefit of it? Why are we choosing option A or B?
  • How are we doing authentication?  Create a google doc?  Gather information?
  • What are the differences between those two workflows?
  • Workflow 2: No human interaction first
  • What is the source of the data?  What is the source of the creator? What about the creator of the Al algorism? What is the source of how it was generated? Bringing different perspective
  • What happens when things fail?  What are the solutions for workflow 1 and workflow 2?
  • Let’s think if it this topic is in our scope? Let’s remember that we are in the product design. Is it really in our scope? It can be discussed how we need to convey the information, flow information from back and forth. What is the standard practice? 
  • You need to identify the version of AI, who certificates that??? How do we want to do it?  Why do we want to pass the information back and forward?  Do we want to help FDA to certificate those algorithms
    • What is the minimum necessary, exchange measurable data/ value? How do we define those actors, scenarios, and traceability?
    • Where does this work belong? Are we expanding HL7 or DICOM, or IHE? Who is really interested in in the workflow? There are multi ways of doing things.  Maybe through FHIR observations? What type of standard we could use? Let’s prepare a draft of what people want to do?   Can we jump into technical side of it? What is the best way of communicating this?

Next Steps:

  • Establish plan to create draft proposals to address scenarios.
  • Flush out those two use cases.
  • Select volunteers.
  • Chris Treml will create Google Docs for both scenarios and send out the links to volunteers.
  • Look for any additional scenarios that should be explored (short term or long term).
  • Schedule a doodle survey poll to schedule next call on this topic.

Here is the list of volunteers’ names provided in the chat window at the end of the call:

  • Elad Walach (Aidoc)
  • Brad Genereaux (Agfa HealthCare)
  • Ilya Goldberg, (Mindshare Medical)
  • Chris Spring  (M*Modal )
  • Andrei Leontiev  (Visage Imaging)
  • Alexander van Eck- (Aidence)
  • Adlon Pereira (Qure)
  • Yongjian Bao (GE Healthcare)
  • Maurizio Menni (GE Healthcare)
  • Katelyn Nye Nye, Katelyn (GE Healthcare)
