Abstract

Purpose

Development of a visualization system that provides surgical instructors with a method to compare the results of many virtual surgeries (n > 100).

Methods

A masked distance field models the overlap between expert and resident results. Multiple volume displays are used side-by-side with a 2D point display.

Results

Performance characteristics were examined by comparing the results of specific residents with those of experts and the entire class.

Conclusions

The software provides a promising approach for comparing performance between large groups of residents learning mastoidectomy techniques.
