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.
