Can a Machine Learn from Radiologists’ Visual Search Behaviour and Their Interpretation of Mammograms—a Deep-Learning Study

摘要

Foveal areas (FAs) are the breast areas measuring 2.5° radial angle consisting of at least 3 temporally sequential fixations. These are highlighted with white circles. Red star indicates true malignancy, and blue square mark indicates location where a radiologist reported a malignant finding. Green points and dotted lines represent the temporal visual search behaviour (fixation points and the temporal sequencing amidst these points). The FAs (total 2) containing blue star in this figure on the right view have been classified as True Positive (TP) as the true cancer lies within the FA
