Image Guided Surgery

Slide 2

Conventional Surgery: Seeing surfaces

Provided by Nakajima, Atsumi et al.

Slide 3

Computer Assisted Surgery: seeing through surfaces

Slide 4

Goal: Assist Surgeons

• Surgical Planning & Simulation– Maximize Tumor Removal– Minimize Damage to Critical Structures

• Intraoperative Visualizations via 3D Slicer

Slide 5

Preoperative Image Information

• High resolution structural MRI

• SPECT images– perfusion– metabolism

• MR Angiography, vessel models

• Diffusion Tensor MRI

• fMRI

• Electro-Cortical Stimulation

Slide 6

Pre-Operative Image Processing

• Construct 3D Models– Semi-Automated Segmentation – DTMRI Tract Tracing

• Register all pre-operative data

Slide 14

Intraoperative Image Processing

• Acquire one or more volumetric (interventional) MRI (iMRI) images

• Determine non-rigid registration of Pre- and Intra-operative data

Slide 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
