The TopCoW Challenge -- Topology-Aware Circle of Willis Segmentation for CT and MR Angiography
Kaiyuan Yang, Fabio Musio, Yihui Ma +112
The Circle of Willis (CoW) is an important network of arteries connecting major circulations of the brain. Its vascular architecture is believed to influence the risk, severity, an…
Unsupervised particle sorting for high-resolution single-particle cryo-EM
Ye Zhou, Amit Moscovich, Tamir Bendory +1
Single-particle cryo-Electron Microscopy (EM) has become a popular technique for determining the structure of challenging biomolecules that are inaccessible to other technologies.…
From Machine to Machine: An OCT-trained Deep Learning Algorithm for Objective Quantification of Glaucomatous Damage in Fundus Photographs
Felipe A. Medeiros, Alessandro A. Jammal, Atalie C. Thompson
Previous approaches using deep learning algorithms to classify glaucomatous damage on fundus photographs have been limited by the requirement for human labeling of a reference trai…
Spinal cord gray matter segmentation using deep dilated convolutions
Christian S. Perone, Evan Calabrese, Julien Cohen-Adad
Gray matter (GM) tissue changes have been associated with a wide range of neurological disorders and was also recently found relevant as a biomarker for disability in amyotrophic l…
A systematic study of the class imbalance problem in convolutional neural networks
Mateusz Buda, Atsuto Maki, Maciej A. Mazurowski
In this study, we systematically investigate the impact of class imbalance on classification performance of convolutional neural networks (CNNs) and compare frequently used methods…
Iterative Inversion of Deformation Vector Fields with Feedback Control
Abhishek Kumar Dubey, Alexandros-Stavros Iliopoulos, Xiaobai Sun +2
Purpose: Often, the inverse deformation vector field (DVF) is needed together with the corresponding forward DVF in 4D reconstruction and dose calculation, adaptive radiation thera…
