• Next Steps
• Initiate manufacturer-driven discussion on
  methods for distributing and testing a purely
  digital version of the reference phantom
• Test digital reference object on 3rd party review
  stations
• Initiate IHE process for manufacturer-driven
  roll-out
• Explore potential for moving further up the data
  generation stream, i.e., closer to raw data
