Possible application areas / IDEAS

  • Acquiring 3D data sets for US, did we acquire all we need?
  • Uncertainty in navigation information
  • Brain / Structure Shift
  • reduce complexity of displays by offloading to audio
  • Depth cues for 3D data (shown on 2D screens)
  • coverage of needle in US

Project Description

Objective

  • Explore possibilities of auditory display for intraoperative use
  • Find opportunities for extending existing projects with auditory display

Approach, Plan

  • common sound synthesis software: PureData, Max, or SuperCollider DOWNLOAD PUREDATA EXTENDED>>> here
  • Test program for Puredata to listen for incoming OSC messages: link
  • libraries for OpenSoundControl include C++: liblo, Python: PyLiblo

Progress

  • Existing methods for intraoperative navigation guidance already implemented in Puredata, see for ureteroscopydownload link, for ablation needle insertion
  • Tried out iplementing liblo library for OSC messages, this workson Mac but not well on Windows.
  • Switched to python-based library, which works well. Rocio tried this out but not enough time to integrate with their existing apps.
  • Friendly contact between groups who are interested in working together (Rocio, Tamas, Elvis, Longquan)


Code from Jay Jagadeesan for OgenIGTLink, here as zip. Only for Linux and Mac system, as the "lo" library has some build issue with visual studio. For windows user, it is recommended to use the python version of lo [1] Simplified version from Longquan Chen
