Goal Assist Surgeons

• Surgical Planning Simulation
• Maximize Tumor Removal
• Minimize Damage to Critical Structures
• Intraoperative Visualizations via 3D Slicer

5
Preoperative Image Information

• High resolution structural MRI
• SPECT images
• perfusion
• metabolism
• MR Angiography, vessel models
• Diffusion Tensor MRI
• fMRI
• Electro-Cortical Stimulation

6
Pre-Operative Image Processing

• Construct 3D Models
• Semi-Automated Segmentation
• DTMRI Tract Tracing
• Register all pre-operative data

Intraoperative Image Processing

• Acquire one or more volumetric (interventional)
  MRI (iMRI) images
• Determine non-rigid registration of Pre- and
  Intra-operative data

15
Construct Intraoperative Visualization

• transmit image data and 3D models thru volumetric
  deformation
• integrate with iMRI images and models
• display with 3D Slicer
• LCD screen in front of surgeon in iMRI
• coordinate visualization with intraoperative
  instruments
