Presentation Transcript

  1. Image Guided Surgery

  2. Conventional Surgery: Seeing surfaces Provided by Nakajima, Atsumi et al.

  3. Computer Assisted Surgery: seeing through surfaces

  4. 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

  7. Integrated Preoperative Data F. Talos

  8. Patient-specific models • Gering_fmri

  9. Segmentation of Neural Structures

  10. DT-MRI Tractography H.J. Park, M.E. Shenton, C.-F. Westin

  11. Preoperative fMRI, Motor Experiment F. Talos

  12. Oligodendroglioma – DT-Tractography + fMRI F. Talos

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

  14. 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

  15. fMRI Projected into Intraoperative Brain Configuration Provided by Alida Tei
