The REFLACX dataset contains eye-tracking data for 3,032 readings of chest x-rays by five radiologists. The dictated reports were transcribed and have timestamps synchronized with the eye-tracking data.

Localization labels for abnormalities are very costly, and the collection of eye-tracking data and reports for implicit localization labels may be an alternative for scaling up data collection. One of the potential uses for these data is in additional supervision for training computer vision models.
