LGAN: Lung Segmentation in CT Scans Using Generative Adversarial Network
This work addresses the need for automated lung segmentation in medical imaging, offering a simplified method that is incremental over existing approaches.
The authors tackled lung segmentation in CT scans by proposing LGAN, a GAN-based schema that simplifies the process and achieves good performance, as evaluated on 220 CT scans with segmentation quality and shape similarity metrics.
Lung segmentation in computerized tomography (CT) images is an important procedure in various lung disease diagnosis. Most of the current lung segmentation approaches are performed through a series of procedures with manually empirical parameter adjustments in each step. Pursuing an automatic segmentation method with fewer steps, in this paper, we propose a novel deep learning Generative Adversarial Network (GAN) based lung segmentation schema, which we denote as LGAN. Our proposed schema can be generalized to different kinds of neural networks for lung segmentation in CT images and is evaluated on a dataset containing 220 individual CT scans with two metrics: segmentation quality and shape similarity. Also, we compared our work with current state of the art methods. The results obtained with this study demonstrate that the proposed LGAN schema can be used as a promising tool for automatic lung segmentation due to its simplified procedure as well as its good performance.
