Journal ArticleDOI
Deep learning in medical imaging and radiation therapy.
Berkman Sahiner,Aria Pezeshk,Lubomir M. Hadjiiski,Xiaosong Wang,Karen Drukker,Kenny H. Cha,Ronald M. Summers,Maryellen L. Giger +7 more
TL;DR: The general principles of DL and convolutional neural networks are introduced, five major areas of application of DL in medical imaging and radiation therapy are surveyed, common themes are identified, methods for dataset expansion are discussed, and lessons learned, remaining challenges, and future directions are summarized.
Journal ArticleDOI
Mass detection in digital breast tomosynthesis: Deep convolutional neural network with transfer learning from mammography
TL;DR: Large data sets collected from mammography are useful for developing new CAD systems for DBT, alleviating the problem and effort of collecting entirely new large data sets for the new modality.
Journal ArticleDOI
Urinary bladder segmentation in CT urography using deep-learning convolutional neural network and level sets
Kenny H. Cha,Lubomir M. Hadjiiski,Ravi K. Samala,Heang Ping Chan,Elaine M. Caoili,Richard H. Cohan +5 more
TL;DR: The authors demonstrated that the DL-CNN can overcome the strong boundary between two regions that have large difference in gray levels and provides a seamless mask to guide level set segmentation, which has been a problem for many gradient-based segmentation methods.
Journal ArticleDOI
Multi-task transfer learning deep convolutional neural network: application to computer-aided diagnosis of breast cancer on mammograms.
Ravi K. Samala,Heang Ping Chan,Lubomir M. Hadjiiski,Mark A. Helvie,Kenny H. Cha,Caleb Richter +5 more
TL;DR: It is demonstrated that multi-task transfer learning may be an effective approach for training DCNN in medical imaging applications when training samples from a single modality are limited.
Journal ArticleDOI
Breast Cancer Diagnosis in Digital Breast Tomosynthesis: Effects of Training Sample Size on Multi-Stage Transfer Learning Using Deep Neural Nets
Ravi K. Samala,Heang Ping Chan,Lubomir M. Hadjiiski,Mark A. Helvie,Caleb Richter,Kenny H. Cha +5 more
TL;DR: It is demonstrated that, when the training sample size from the target domain is limited, an additional stage of transfer learning using data from a similar auxiliary domain is advantageous.
