  • Queen's University: Tamas Ungi

Objective

The goal of this project is to a develop a needle detection method in tracked ultrasound for application in gynecological brachytherpay. We will try to develop code inside slicer to automatically detect and segment the gynecological brachytherapy needles using online tracked ultrasound images. Our system will use an electromagnetic tracking system and also Plus ultrasound library.

Approach, Plan

  • Set-up and configure the hardware/software of the tracked ultrasound system using NDI Aurora, BK ultrasound, 3D Slicer and Plus Library.
  • Perform all the prerequisite calibration and registration.
  • Develop code for tracked ultrasound feature extraction, needle detection and segmentation.
    • 3D reconstruction of needle.
    • Online visualization and needle navigation.
  • Embed to a Slicer module
  • Test the method on our gynecologic phantom, using BK trans-abdominal probe and gynecologic brachytherapy needles.

Progress

TBD


Delivery Mechanism

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