Pulmonary Nodule Detection in CT Images via Deep Neural Network

In recent years nodule candidate detection becomes the basis of the automated pulmonary nodule detection system, of which the the upper bound limit performance is determined by the sensitivity of nodule candidates detection. This paper is to improve the nodule candidate detection using deep neural networks. We treat the nodule detection task as pixel-level segmentation problem. Based on the 2D U-NET network. We build a multi-level network to...
