Quantitative Analysis of Contouring Performance Among Novice Residents and Implications for Future Educational Efforts

Summary: Effective contouring education is vital in radiation oncology residency training, as research links contouring variability to negative patient outcomes. Teaching this skill requires understanding common errors made by novice residents. We conducted a study using an interactive online platform to compare novice resident performance against an expert on real patient cases. We hypothesized this software would identify key mistakes and teaching points for residents before their disease-site-specific training.
