PDI Value Proposition

• Interoperability validation is especially
  important for media
• Network Interoperability Problems
• Immediate, Unambiguous
• Rapidly resolved
• Media Interoperability Problems
• Long delays in detection and recognition
• Ambiguous or unknown source vendor/version
• Long delays in resolution
• Large volume of non-interoperable media created
  due to delays
• IHE Virtual Connectathon for PDI solves the media
  validation problem
• Provides rapid, unambiguous detection of problems
• Enabling rapid resolution of problems

  is done by both MESA tools and the project
  managers.
• IHE_PDI web content corresponds exclusively to
  the DICOM content, although it need not represent
  the entire DICOM content.
• Other content will not be placed in DICOM or
  IHE_PDI directories, but may be placed in other
  locations on the CDROM.
• Do not assume that an application on the media
  will automatically be launched. IHE recommends
  that media readers not automatically run software
  on the media.
• Web content use of XHTML and JPEG formats is
  restricted to ensure interoperability.
