Abstract

Chest x-ray (CXR) is widely applied for the detection and diagnosis of children’s lung diseases. Lung field segmentation in digital CXR images is a key section of many computer-aided diagnosis systems.In this study, we propose a method based on deep learning to improve the lung segmentation quality and accuracy of children’s multi-center CXR images.The novelty of the proposed method is the combination of merits of TransUNet and ResUNet. The former can provide a self-attention module improving the feature learning ability of the model, while the latter can avoid the problem of network degradation.Applied on the test set containing multi-center data, our model achieved a Dice score of 0.9822.This novel lung segmentation method proposed in this work based on TransResUNet is better than other existing medical image segmentation networks.© 2023 Chen, Yu, Huang, Shu, Kuosmanen, Shen, Ma, Li, Sun, Li, Shu and Yu.
