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.
