Objective

The goal of this project is to develop 2D ultrasound technology for image-guided procedures.

Specifically, we focus on ultrasound image processing techniques that can operate in a complementary fashion with external probe tracking systems. For instance, to achieve 3D reconstruction and online visualization in the context of image-guided neurosurgery, where calibrated or tracked ultrasound may not be available.

Approach, Plan

• Develop code (C++) for trackerless ultrasound feature matching and associated applications
  • 3D reconstruction
  • Online visualization / navigation
• Port to a Slicer module
• Testing algorithms on US data provided by PLUS, Tamas.

Progress

• External build of nlopt library for Slicer (Thank you jc)
• Developed algorithm and c++ code for trackerless US plane localization
• Developed slicer module for trackerless US plane localization

Delivery Mechanism

• Code and slicer module
• A writeup of developments/results for future publications.
