Project Description

Objective

• Implement communication between 3D Slicer and Koh Young's new optical tracking system for neurosurgical navigation
  • Real-time tracking data
  • Surface model data for surface registration
  • Intraoperative registration update

Approach, Plan

• Currently no actual device exists.
• Protocol has been defined in November - December 2014
• Create simulator software to test the feasibility of the protocol
  • 3D Slicer
    • OpenIGTLink Interface in 3D Slicer was extended to handle surface model data https://github.com/openigtlink/OpenIGTLinkIF/pull/45
    • Python module has been created / need testing
    • Development of Koh Young device simulator is in progress

Progress

• Developed 3D Slicer scripted module to send commands to the sensor controller
• Developed program to simulate the sensor controller
  • Implemented a state machine
  • Tested message exchange with 3D Slicer and state transition
