Project Description

Objective

• Improve performance and usability of NeedleFinder [ADD A SHORT MOVIE TO SHOW WHAT IT DOES TODAY]
  • Code profiling, refactoring
  • GUI simplification
    • Provide Bounding Box/Region of Interest
  • Semi-Automatic needle tip (and body) detection
  • Parameter optimization

Approach, Plan

• Improvements of the source code quality, algorithms and GUI (usability):
  • Ad-hoc python profiling concept (method tagging, logging and message boxes as code probes)
  • Improved standardized and guided workflow more usable by MDs (state machine)
    • Interaction protocol using existing tools for MD to provide bounding-box quickly
  • Incorporate SimpleITK filtering/preprocessing and a little user interaction (try e.g. derivatives: gradient magnitude, vesselness)
  • Look into machine learning (implement simple genetic algorithm & compare to brute-force grid search)
