Area of Science:

  • Medical Imaging
  • Surgical Navigation
  • Human-Computer Interaction

Background:

  • Current image-guided surgery relies on cross-sectional views or augmented reality for instrument localization.
  • A need exists for simpler, more intuitive interfaces to aid real-time surgical target localization.

Purpose of the Study:

  • To propose and evaluate a minimalistic visual interface for real-time surgical target localization.
  • To assess the interface's effectiveness compared to traditional cross-sectional views.

Main Methods:

  • A novel 3D pose and uncertainty visualization interface was developed.
  • A usability study compared the proposed interface (in surgical microscope oculars) against screen-based cross-sectional views.
  • Electromagnetic navigation in phantoms was used for instrument tracking.

Main Results:

  • Participants showed enhanced localization accuracy and reduced duration for detecting invisible targets.
  • Clinically experienced users achieved shorter trajectories to targets.
  • The proposed interface, in both stand-alone and multi-modal configurations, outperformed cross-sectional views-only navigation.

Conclusions:

  • The minimalistic interface shows potential for accurate navigation with reduced user distraction and workload.
  • Further evaluation in a preclinical setting for auditory brainstem implantation is underway.
