4D Ultrasound / Hybrid Probe / OsteoPlan

Key Investigators

• Brigham and Women's Hospital: Laurent Chauvin, Noby Hata
• PSI: John Magill, Brian Murphy

Objective

1. 4D Ultrasound: Develop a 4D Ultrasound on Slicer (Laurent Chauvin) with mitral valve (shape, position) tracking (Atsushi Yamada)
2. Hybrid Probe: Develop a Slicer module to register EM Probe (NDI Aurora System) and Optical Probe (BrainLab System), to create one hybrid probe (Laurent Chauvin)
3. OsteoPlan: Develop a Slicer module (wizard) for osteotomy, for facial reconstruction (Laurent Chauvin, PSI)

Approach, Plan

1. 4D Ultrasound: Use OpenIGTLink to receive 3D data from scanner (for now, simulating scanner), and using Volume Rendering module (GPU Ray casting) to render the volume. A Slicer module will be develop to navigate through the different volume received.
2. Hybrid Probe: Use a pivot calibration to find the tip of the probe, with both systems, and use a pair point registration, to find transformation from Aurora coordinate system to Polaris (and then BrainLab) coordinate system.
3. OsteoPlan: Create a wizard with 5 different steps (cut the model, select different parts of the model, move parts, place fiducials, back to original position)

Progress

1. 4D Ultrasound: Receiving data through OpenIGTLink and using Volume Rendering is working. Need to make mitrale valve detection, and develop module to store 3D volumes on Slicer. Probably need multithread.
2. HybridProbe: Pivot calibration worked (NDI Toolkit), Registration worked. Need to implement BrainLab system.
3. OsteoPlan:Basics are done. Clipping issue (cutter too thin) has been fixed ! Need to make the interface more user friendly (placing distractor, reduce number of clicks)
