  • Abstract: Lung nodule segmentation can help radiologists' analysis of nodule risk. Recent deep learning based approaches have shown promising results in the segmentation task. However, a 3D segmentation map necessary for training the algorithms requires an expensive effort from expert radiologists. We propose a new method to train the deep neural network, only utilizing diameter information for each nodule. We validate our model with the LUNA16 dataset, showing competitive results compared to the previous state-of-the-art methods in various evaluation metrics. Our experiments also provide plausible qualitative results comparable to the ground truth segmentation.
