The general navigation system consists of the following components:

  • Slicer3: the base platform for navigation
  • IGT loadable modules: Software modules, pluginned into Slicer3, for supporting IGT specific functionality
  • IGSTK: An interfacing tool for common commercial tracking devices
  • Tracking device: e.g. NDI Aurora tracking system


This tutorial explains how to set up a general navigation system with a tracking simulator.

Step 1: Install Slicer3

Step 2: Install OpenIGTLink module

  • Unzip the binary and copy all files into your-slicer3-build(install)-directory/lib/Slicer3/Modules.
  • You should see OpenIGTLink in the Slicer3 module list after Slicer is started.

Step 3: Install tracker simulator

  • This tracker simulator will generate and send fake tracking data to Slicer3. Download one of the following binaries:
    • For Linux (x86, 32-bit), click here.
    • For Linux (x86, 64-bit), click here.
    • For Windows (32-bit), click here.
    • For Mac OS X (x86), click here.
  • Unzip the binary to some place on your computer.

Step 4: Perform navigation

  • Run Slicer3. In the top directory of your Slicer3 installation, run this command to start up Slicer3:
./Slicer3
  • Set up OpenIGTLink module
  • Run tracking simulator
