TL;DR: In this article, the authors used federated learning to predict future oxygen requirements of symptomatic patients with COVID-19 using inputs of vital signs, laboratory data and chest X-rays.
Journal ArticleDOI
Sparse-View Spectral CT Reconstruction Using Spectral Patch-Based Low-Rank Penalty
Kyungsang Kim,Jong Chul Ye,W. A. Worstell,Jinsong Ouyang,Yothin Rakvongthai,Georges El Fakhri,Quanzheng Li +6 more
TL;DR: This paper proposes a penalized maximum likelihood method using spectral patch-based low-rank penalty, which exploits the self-similarity of patches that are collected at the same position in spectral images and improves spectral images both qualitatively and quantitatively.
Journal ArticleDOI
Complex Gaussian Scale Mixtures of Complex Wavelet Coefficients
TL;DR: The experimental results show that using the CGSM of complex wavelet coefficients visually improves the quality of denoised images from the real case.
Journal ArticleDOI
Spectral CT Using Multiple Balanced K-Edge Filters
Yothin Rakvongthai,W. A. Worstell,Georges El Fakhri,Junguo Bian,Auranuch Lorsakul,Jinsong Ouyang +5 more
TL;DR: The proposed cost-effective system design using multiple balanced K-edge filters can be used to perform spectral CT imaging at clinically relevant flux rates using conventional detectors and integrating electronics.
Journal ArticleDOI
Direct reconstruction of cardiac PET kinetic parametric images using a preconditioned conjugate gradient approach.
Yothin Rakvongthai,Jinsong Ouyang,Bastien Guerin,Quanzheng Li,Nathaniel M. Alpert,Georges El Fakhri +5 more
TL;DR: A novel approach based on the PCG algorithm to directly reconstruct cardiac PET parametric images from sinograms, and yield better estimation of kinetic parameters than the conventional indirect approach, i.e., curve fitting of reconstructed images.
