Outline of Research at the Start

本研究は,放射線科医が行う画像診断(読影)のパフォーマンスと視覚認知パターンの関係を調査し,ここから医師の診断方略の特徴と,その背後にある優れた技能の特徴を解明することが目的である.放射線科の協力者を対象に,胸部X線画像およびCTスキャン画像に対する診断時の眼球運動データを獲得し,視覚認知パターンを明らかにし,高度技能との関連性について知見を得る.

Outline of Final Research Achievements

The present study aimed at developing the reverse inference approach to interpret eye tracking data during performing cognitive tasks, and implementing it to the analysis of skills in diagnosing chest XP images by medical doctors. In the study, the doctors’ strategy for effective diagnoses as well as their corresponding eye movement patterns were systematically identified. Based on the data analysis, the knowledge of well-skilled doctors’ strategies, and their differences from those held by doctors having different background and residents could be obtained.

Academic Significance and Societal Importance of the Research Achievements

一般に実施が困難な認知作業分析を,扱いが困難な眼球運動データを効率的に解釈していく手順を準備することによって,専門的知識を有さない人でも実施が可能なアプローチ方法を提供することができた.さらにこれを医師の胸部XP画像診断を対象とした分析に適用することで,高度な技能に関する知見を得ることができた.
