Towards NousNav Major Version Release

Key Investigators

Presenter location: In-person

Project Description

NousNav is an ongoing project led by Dr. Alex Golby at Brigham and Women’s Hospital to build and disseminate a low-cost neuronavigation system. Built as a 3D Slicer Custom App, NousNav uses low cost optical tracking (Optitrack Duo) in combination with custom optically-tracked tools and reference arrays to facilitate patient registration, procedure planning, and navigation.

For this project we are going to finalize remaining issues on the tracker to move towards a 1.0 release


  1. Triage existing issues into a major/minor release tasks
  2. Clear issues for the 1.0 Release

Approach and Plan

Major tasks to work on:

  1. DICOM patient management
    1. Storage of MRBs as secondary captures
    2. Store XML only?
  2. Landmarks management rework
    1. Granular color management
    2. Single landmarks class
  3. LPS orientation in Nav phase

Progress and Next Steps

  1. Reworked the registration landmark support.
    1. Support any sufficient subset of the complete landmark list
    2. Registration picking provides better control of order of landmark collection
    3. Improved color consistency across landmark usage
  2. Made patient interface styling consistent with rest of application
  3. Demo’d recent changes to the rest of the NousNav team
  4. Discussed with other IGT devs the best way to reuse NousNav effort in other projects
    1. Slicer NavigationAppTemplate: core functionality of the NousNav workflow made available as a reusable template similar to SlicerCAT
  5. Will tag the 1.0 release at the end of this week.
