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 Slide 2 Tracking Systems GE InstatrakEM Tip TrackingMRI NDI PolarisPassive optical, hybrid AuroraEM IGT FlashpointActive optical Robin Medical EndoscoutEM / MRI gradient Biosense Webster CARTOEM / induction coil Ascension Bird, MicrobirdEM Slide 3 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.
