چکیده
Locating lung field is a critical and fundamental processing stage in the automated analysis of chest radiographs (CXRs) for pulmonary disorders. During routine examination CXRs, using both frontal lateral CXRs can benefit clinical diagnosis cardiothoracic diseases. However, accurate segmentation fields on still challenging due to blurry boundary poor generalization ability models. Existing deep learning-based methods focused these different type (e.g., pediatric CXRs) new diseases COVID-19) has not been tested. In this paper, view identification assisted fully convolutional network (VI-FCN) proposed simultaneously. The VI-FCN consists an FCN branch enhancing segmentation. To improve VI-FCN, six public datasets our (over 2000 were collected training. Japanese Society Radiological Technology (JSRT) dataset yields mean dice similarity coefficient (DSC) 0.979 ± 0.008, Jaccard index ( $\Omega $ ) 0.959 0.016, distance (MBD) 1.023 0.487 mm . Besides, achieves DSC 0.973 0.010, 0.947 0.018, MBD 1.923 0.755 CXRs. experiments demonstrate superior performance over most existing state-of-the-art methods. Moreover, promising results untrained COVID-19 datasets.

This paper describes a lung field segmentation method, working on digital Postero-Anterior chest radiographs. The lung border is detected by integrating the results obtained by two simple and classical edge detectors, thus exploiting their complementary advantages. The method makes no assumption regarding the chest position, size and orientation; it has been tested on a non-trivial set of real ...

Computer-aided Diagnosis (CAD) systems can assist radiologists in several diagnostic tasks. Lung segmentation is one of the mandatory steps for initial detection of lung cancer in Posterior-Anterior chest radiographs. On the other hand, many CAD schemes in projection chest radiography may benefit from the suppression of the bony structures that overlay the lung fields, e.g. ribs. The original i...
