9am-10am: OpenIGTLink Updates and Next Steps

• OpenIGTLink Updates
  • Summary from Junichi's presentation on Tuesday
• Discussion on OpenIGTLink Protocol version 2
  • Finalize version 2 protocol
    • Summary of version 2 protocol
    • New support for image-guided systems
      • Discussion on new commands is in progress.
        • Ziv Yaniv (Geogetown) concerns about the fields with fixed length (especially in IMGMETA)
        • How about "length+string" approach?
      • Stealthlink Protocol (for reference)
    • Matlab integration
      • There have been several requests for Matlab OpenIGTLink interface.
      • Prototype Matlab/Octave interface is available.
      • New message type to support "remote procedure call"??

10a-12pm: Tutorial and hands-on session

• Basic: OpenIGTLink tutorial using 3D Slicer and OpenIGTLink
  • Instructions are available in 3D Slicer's OpenIGTLinkIF Documentation.
  • Tracking simulator
  • Imager simulator
• Advanced: Matlab OpenIGTLink
  • Instructions are available in OpenIGTLink / Matlab Interface.
• 5-10 minutes from each of the vendors on how they can use it?
• Hands-on session
  • Planning to interface aurora tracker with Slicer using OpenIGTLink (Tamas)
  • Hands-on help in WPI system up and running (Greg will confirm)

1-2pm: Demos of working OpenIGTLink based systems

• IGSTK-OpenIGTLink by Haiying Liu
• BrainLAB-3D Slicer Integration

2-3pm: OpenIGTLink Library, 3D Slicer and other tools

• Transport Layer
  • Message queueing idea/transport layer (Patrick Georgetown, Steve to followup)
    • For latest update on this, please refer to the CTK wiki: http://www.commontk.org/index.php/Documentation/Messaging
    • Suggestion: use Message Bus and Publisher/Subscriber design pattern for system integration
    • OpenIGTLink can be used to define the common message schema, and ZeroMQ can be used to handle the transportation layer abstraction
    • ZeroMQ is a small and fast implementation of the Advanced Message Queuing Protocol under the LGPL license
    • It supports both synchronous and asynchronous messaging mode
    • It supportsTCP, Multicast/PGM, Inter-process, and inter-thread transportation
    • CMake version of library can be found here http://github.com/PatrickCheng/zeromq2
    • API can be found here http://api.zeromq.org/zmq.html
• Matlab OpenIGTLink interface
  • Currently it supports IMAGE and TRANSFORM
  • Potential applications?
    • Prototyping robot
    • Prototyping IGS system
  • Other language support
    • Java
    • C#
    • Python

3-4pm: Simulator Discussion

• Currently, only simple simulators are provided as example programs in the OpenIGTLink Library
  • Are they enough?
  • More sophisticated simulator?

Teleconference on May 27 (Thu) 3pm-
