視線を用いた医用画像読影の能力測定アプリケーションの開発と評価

抄録

The purpose of this study is to develop an application software for evaluating skills of medical image interpretation using an eye-tracking technique. Our application software could implement the receiver operating characteristic (ROC) analysis and the ROC-type curve for task of detection and localization, the measurement of omission errors, consisting of scanning, recognition and decision-making error, and the heat-map of fixation. We tried to evaluate some participants, consisting of radiological technologists and students from radiological technology department. This application software allowed to evaluate the interpretation skills depending on user characteristics using the information of eye movements during medical image reading.
