Shift Hours' Impact on Fatigue and Tracking of Eye Dynamics

The goal of this clinical trial is to learn how night shift-induced sleep debt affects oculomotor patterns, attentional state, and diagnostic performance in emergency radiologists. The main questions it aims to answer are: * Does sleep debt from a night shift alter oculomotor parameters, as eyes movements (speed and amplitude), fixation duration, pupil size? * Does a night shift impact radiologists' diagnostic accuracy, attentional state, and perceived fatigue? Researchers will compare radiologists after a night shift (sleep-deprived) with the same radiologists after a night of rest (control) to see if fatigue-related changes affect both visual exploration strategies and diagnostic performance. Participants will: * Perform a guided saccade task assessed by eye tracking (primary endpoint), * Read thoracic CT scans (with and without pulmonary embolism cases) to assess diagnostic performance and visual exploration patterns, * Undergo EEG recording to measure attentional state, * Complete self-report questionnaires on sleepiness and fatigue.
