摘要:

Lung cancer is one of the primary lung malignant tumour with the fastest increasing morbidity and mortality and the greatest threat to people's health and life. Early detection of lung cancer can significantly increase patients' chance of survival. Lung parenchymal segmentation is an essential pre-processing step for analysing thoracic computed tomography(CT) images. Conventional methods for lung segmentation rely on user generated features, and do not segment lung parenchymal with juxta-pleural nodules accurately. Deep learning has outperformed other methods in image classification and target recognition tasks. In this study, a new dilated convolutional based weighted fully convolutional network (FCN) has been proposed for the segmentation of lung parenchyma to minimize the juxta-pleural nodule issue. The effectiveness of this method was verified by experiments on 173,694 diagnosis CT images of lungs and their corresponding segmentation maps. The Dice similarity coefficient and pixel accuracy achieved are 0.9702 and 0.9833 respectively. The experiment results show that the proposed method can provide more accurate and robust results than traditional FCN. © 2020 Journal of Physics: Conference Series.
