Agenda
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)
- Discussion on new commands is in progress.
- 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"??
- Finalize version 2 protocol
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
- Message queueing idea/transport layer (Patrick Georgetown, Steve to followup)
- 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-
