Abstract: The predominant source of medical errors in radiology is surprisingly not deficient medical knowledge. Rather, errors primarily stem from the methods radiologists use to visually inspect the image, referred to as “perceptual errors.” Perception-related errors are estimated to reach 33% on abnormal chest radiology exams. To mitigate this problem, radiologists employ personalized and high-dimensional visual search strategies, otherwise known as search patterns. Quantitative descriptions of these search patterns via direct observation or self-report are not only unreliable, but also interfere with quality improvement interventions, which therefore negatively impact patient care. Through the use of eye-tracking technology and feature extraction we can employ novel techniques to improve health care quality, passively label datasets, and vet the next cohort of medical practitioners.
