Figure 1.
Visual assessment of the ResNet-50 classification results of a radiograph of a dog showing an alveolar pattern in the cranial lung lobe. The activations of the last layer are visualized superimposed on the radiographs. Each image corresponds to the activations for a specific radiographic finding. The alveolar pattern was correctly identified by the model (B) however the model also falsely identified the presence of a mass (E). (A) Original image, (B) alveolar pattern, C bronchial pattern, (D) cardiomegaly, (E) mass, (F) interstitial pattern, (G) pleural effusion, (H) pneumothorax, (I) unremarkable.
