Slicer3: Image Guided Therapy (IGT)

Introduction

The Slicer3 IGT tools are intended to enable research in image guided therapy. They leverage the Slicer environment and augment it with a number of IGT specific functionalities and modules. One key element of this capability is Open IGT link, a communication protocol to link 3D Slicer to a variety of devices.

Use-case scenario 1: Neurosurgical navigation

• I am a neurosurgeon who is using the BrainLabs Navigation system. I would like to use Slicer to do some research in DTI visualization during procedures. What do I do?
  • The integration of BrainLab, BioImage Suite and Slicer3

Use-case scenario 2: IGT robotics tutorial with LEGO Mindstorms

• I am a professor who wants to use Slicer to educate my students about the basics of robotics in IGT

Overview

This tutorial provides a thorough understanding of the main concepts in image-guided therapy and medical robotics, namely imaging, pre-operative planning, targeting by tracking, navigation and registration. The tutorial is open-source and completely free for anyone to use or modify (see http://www.slicer.org for details and for the BSD style open source license).

The tutorial is:

• Hands-on: Using a LEGO robot, a LEGO phantom (anatomical model) and a tutorial module in 3D Slicer v. 3 means that tutorial participants can use real physical equipment and software to learn about IGT and medical robotics.

• Accessible: The tutorial software is open-source, and the cost of the materials is approximately $300 USD + shipping and taxes.
