Agenda

• No meeting next monday July 3, 2023 due to holidays
• SIIM
  • High awareness of cloud in medical imaging
    • Year ago - "are you moving to the cloud"
    • This year - "we are moving to the cloud"
  • Heard of one customer who trained a generative ai model on the DICOM metadata and cloud ask it questions like "how many studies are CT Head with and without constrast"
  • One poster from emory used chatgpt to convert a radiology report into something more consumable by clinician/patient
    • https://pubmed.ncbi.nlm.nih.gov/37014240/
• Azure released a capped egress program for express route
  • https://azure.microsoft.com/en-us/pricing/details/expressroute/#pricing
• DICOM Supplement 223 SIIMcast
  • https://siimcast.libsyn.com/s6e13-dicom-supplement-223
  • From WG33 - focused on migrations
  • SIIM has been involved
• HTJ2K Supplement - moving to letter ballot
• AHLI
  • returns HTJ2K lossless only
    • Wanted to simplify building of medical imaging apps - only one codec
    • wanted to ensure fast and cost effective applications
      • Avoid transcoding
      • Avoid differente user experiences due to variance in codec decode performance / conpression size
  • DICOMweb not supported yet - so no progressive that way, customers using aws sample for this now:
    • https://github.com/aws-samples/amazon-healthlake-imaging-samples
• Two best DICOM codecs for archviing (space)
  • JPEG2000
  • JPEG-LS <- best because much faster (10x) that JPEG2000 with similar compression ratio
  • Most vendors do not support JPEG-LS, but just the two:
    • JPEG Lossless <- preferred because faster than JPEG2000
    • JPEG2000
• Codec licensing issues contributed to the forking of Osirix into Horos
  • Also 64 bit support - which Osirix charged for
• Miele-lxiv - Osirix/Horos port to windows?
  • https://github.com/bettar/miele-lxiv
  • WIP - a bit flaky/crashybuggy
