The general navigation system consists of the following components:<br>
* 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 these components to build and use a general purpose navigation system.
<br><br>
=== '''Step 1: Install Slicer3''' ===
Follow the instructions here to install Slicer3:<br>
http://wiki.na-mic.org/Wiki/index.php/IGT:ToolKit/Install-Slicer3

=== '''Step 2: Install OpenIGTLink module''' ===
OpenIGTLink protocol handles data communication between Slicer3 and tracking device ([http://wiki.na-mic.org/Wiki/index.php/OpenIGTLink Click here for details]). As a loadable module in Slicer3, OpenIGTLink will receive tracking data from the NDI Aurora system.
* If you can find a proper binary here for your computer, download it and unzip the file:
** For Linux box (x86, 32-bit), click [[Media:OpenIGTLink.tgz|'''here''']].
** For Windows box (32-bit), click '''here'''.
** For Mac box, click '''here'''.
* If you'd like to build OpenIGTLink module from the source code, [[IGT:ToolKit/Build-OpenIGTLink|find the instructions here]].
* Copy the binary 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 IGSTK''' ===
IGSTK is used to acquire tracking data from NDI Aurora tracking system.
* If you can find a proper binary here for your computer, download it:
** For Linux box (x86, 32-bit), click [[Media:IGSTKSandbox.tgz|'''here''']].
** For Windows box (32-bit), click '''here'''.
** For Mac box, click '''here'''.
* Unzip the file to '''igt-tutorial'''.

=== '''Step 4: Connect NDI Aurora tracking device''' ===
* Set up your NDI Aurora tracking device
* Connect it to the computer where IGSTK will be run.
** By default, Aurora has only serial port connection.
** If your computer doesn't have a serial port, you need to have a serial-to-USB converter.

=== '''Step 5: Perform navigation''' ===
