Soft Activation Mapping of Lung Nodules in Low-Dose CT images [article]

Yiming Lei, Yukun Tian, Hongming Shan, Junping Zhang, Ge Wang, Mannudeep Kalra
2018 arXiv   pre-print
As a popular deep learning model, the convolutional neural network (CNN) has produced promising results in analyzing lung nodules and tumors in low-dose CT images.  ...  To address this challenge, in this paper we develop a soft activation mapping (SAM) to enable fine-grained lesion analysis with a CNN so that it can access rich radiomics features.  ...  Early detection of lung cancer with low dose CT (LDCT) has been recently approved in some countries including the United States to improve patient survival.  ...
