TL;DR: We proposed the Position Classifier to encode position information, improving the results of diseases identification.
Abstract: The patch-based method of chest X-ray interpretation often suffers from the loss of information regarding global anatomy structures. We propose using a simple position classifier to train the model to encode the correct position information. Our model can accurately encode the position information with a 99.87% AUC score on patch positioning. With the help of position information, our model can filter out anatomy structures that are commonly misinterpreted as lesions. We believe the proposed method is both effective and easy to implement in common deep learning-based diseases identification framework with only slight modifications.
