This study introduces a new visualization system for surgical training, enabling instructors to compare over 100 virtual surgeries. The software effectively assesses resident performance in mastoidectomy techniques.

Area of Science:

  • Medical simulation
  • Surgical education technology

Background:

  • Surgical training requires effective methods for performance assessment.
  • Comparing numerous virtual surgery outcomes presents a significant challenge for educators.

Purpose of the Study:

  • To develop a visualization system for comparing results from over 100 virtual surgeries.
  • To provide surgical instructors with a tool for performance evaluation in surgical training.

Main Methods:

  • Utilized a masked distance field to model overlap between expert and resident surgical performance.
  • Employed multiple side-by-side volume displays alongside a 2D point display for visualization.

Main Results:

  • Examined performance characteristics by comparing individual resident results against expert benchmarks and the entire class.
