Model visualisation based on single cases. (a) Heatmaps of the original model and the model trained using the augmented data. The original model includes cues outside the lungs or even no cues and the model trained using the augmented data shifted the focus to cues within the lungs where the findings are supposed to be. The CXRs are the example of ‘Consolidation’ patients. (b) The heatmaps of a representative case generated by the original model and proposed model for predicting radiological label, race, age, and sex. The original model shows similar distributions across different tasks.
