3D Slicer for Image Guided Therapy Program
Goal:To develop general display, control, and communications modules
providing a resource to support diverse IGT applications– Thermal therapies– Vascular interventions– Surgical excision
Specific Aim: Provide seemless tracking for rigid tools and catheters inside and
outside of MRI scanner.Enable
– Dynamic Volume Acquisition– Continuous 3D Visualization – Real-time MR System Control

Slaving of 3D Slicer Workstation
• Read coordinates from FDA approved system (e.g., GE Navs).
• FDA approved system provides primary source of information to clinician
• 3D Slicer provides augmented information (e.g., DTI) and will serve as a research platform.
Platforms
• 3D Slicer
• Pai Saiveroonporn – Thermal mapping, on-line scanner control
• Ryoichi (under Zientara grant) – Cryo iceball prediction
• Eigil Samset – Oslo
• Randy Ellis – Queens College
• Mike Guttmann - NIH

Open tracker
• www.studierstube.org/opentracker• Developed by Technical University of Graz• flexible XML based tracking framework• source code available under for Windows, Irix
and Linux.• includes drivers for a range of different tracking
systems.• modules for some addition tracking systems
have been developed by Samset et al.• can be used to maintain registration across
different tracking systems
