Lung cancer is a disease of abnormal cells multiplying and growing into a nodule. Our main contributions can be summarized as follows: 1. 2018-06-12: NVIDIA developer news about our MICCAI paper "CT-Realistic Lung Nodule Simulation from 3D Conditional Generative Adversarial Networks for Robust Lung Segmentation". level segmentation with graph-based optimization for the extraction of road topology [17, 8]. lung [27]. For more illustration, please click the GitHub link above. Lung segmentation is the first step in lung nodule detections, and it can remove many unrelated lesions in CT screening images. The lung segmentation images are not intended to be used as the reference standard for any segmentation study. Github Aims. Description; Build LSTK with ITK; Run a segmentaiton example: Video; Previous topic. 2020 International Symposium on Biomedical Imaging (ISBI). However, it’s a time-consuming task for manually annotating different pulmonary lobes in a chest CT scan. In this paper, we propose a new deep learning method to improve classification accuracy of pulmonary nodules in computed tomography (CT) scans. 2018-03-12: One paper is accepted by IEEE Transactions on Affective Computing.
