Dec-2009-SlicerXND-DesignAndEngineering

Logistics

• Confirmed date: Tuesday, December 15 (11-4pm), 2009
• Location: WUSTL Campus, East Building

Goals

The purpose of this meeting is to agree upon an engineering approach and work on interface/interaction design for integrating a future version of XNATDesktop and FileServer into Slicer. The tool is envisioned as an OsiriX-like interface that would be raised when a user selects File->Import ->Load ->Export ->Save from Slicer. It can also operate as a standalone tool, to browse, preview, mark-up remote or local datasets -- and to launch Slicer to view a selected dataset or scene. Issues to consider:

Design

• Review initial mockups, consider them against engineering practicalities
• Agree upon "bare-bones" presentation skeleton for functionality (first pass).
• Collaboration plan for merging design and engineering

Engineering

• How to leverage existing XND codes
• Java QT? -- Jambi?
• PACS interaction

Deliverables

• Report on all issues above
• Propose a timeline to be reviewed by Dan, Steve, Ron

Questions

• When we search for all MRML files, or all MRML files within a project on XNAT, what do we need to know about the returned query results?
  • Ron would like thumbnails generated at scene-Save for the scene as-is and for each scene snapshot.
  • May want to know the data files referenced by the scene file?
  • Do we want to know what the scene tree looks like?
  • want Separate viewer for MRML files? (tree-view like that in Slicer?)
  • useful to have rudimentary DCOM db structure-like catalog in mrml file?
• We NEED a sensible way for the layout to respond to content types / data formats that admit or do not admit thumbnails and previews.
  • Keep things in the same window (no popups)
  • Don't have empty frames that may lead to confusion (at first glance) that there's an error
  • DICOM files may have thumbnails and previews
  • NRRD files: will they have thumbnails and previews?
  • MRML files: will have thumbnails but no previews.
  • .vtk files: will have no thumbnails and no previews.
  • random associated data -- txt files, etc. no thumbnails and no previews
• Should XND/fileserver implement SCP/SCU?
  • DICOM listener
  • DICOM query/retrieve

Schedule

• Tues - Dec 15th
  • 11:00-2:00 - Design and Engineering discussion: determine:
    • scope of functionality & rough out compatible GUI skeleton
    • existing functionality we can leverage
    • extisting functionality that can be extended
    • new functionality that should be developed
    • confirm appropriate development tools (for logic & gui)
  • 2:00-3:30 prioritize proposed functionality & timelines
    • determine first-pass implementation goals & fit to timeline
    • rough out design GUI skeleton for first-pass
    • fit all proposed functionality & GUI extensions to timeline
  • 3:30-4:00 - Decide on collaborative work strategy

Attendance

• We hope to keep this group small and tight for this first meeting:

1. Mikhail Milchenko
2. Wendy Plesniak
