Texture Matching GAN for CT Image Enhancement
Madhuri Nagare, Gregery T. Buzzard, Charles A. Bouman
Deep neural networks (DNN) are commonly used to denoise and sharpen X-ray computed tomography (CT) images with the goal of reducing patient X-ray dosage while maintaining reconstru…
Generative Plug and Play: Posterior Sampling for Inverse Problems
Charles A. Bouman, Gregery T. Buzzard
Over the past decade, Plug-and-Play (PnP) has become a popular method for reconstructing images using a modular framework consisting of a forward and prior model. The great strengt…
Dynamic DH-MBIR for Phase-Error Estimation from Streaming Digital-Holography Data
Ali G. Sheikh, Casey J. Pellizzari, Sherman J. Kisner +2
Directed energy applications require the estimation of digital-holographic (DH) phase errors due to atmospheric turbulence in order to accurately focus the outgoing beam. These pha…
Projected Multi-Agent Consensus Equilibrium (PMACE) with Application to Ptychography
Qiuchen Zhai, Gregery T. Buzzard, Kevin Mertes +2
Multi-Agent Consensus Equilibrium (MACE) formulates an inverse imaging problem as a balance among multiple update agents such as data-fitting terms and denoisers. However, each suc…
X-ray Spectral Estimation using Dictionary Learning
Wenrui Li, Venkatesh Sridhar, K. Aditya Mohan +5
As computational tools for X-ray computed tomography (CT) become more quantitatively accurate, knowledge of the source-detector spectral response is critical for quantitative syste…
Ringing Artifact Reduction Method for Ultrasound Reconstruction Using Multi-Agent Consensus Equilibrium
Abdulrahman M. Alanazi, Singanallur Venkatakrishnan, Gregery T. Buzzard +1
Non-destructive characterization of multi-layered structures that can be accessed from only a single side is important for applications such as well-bore integrity inspection. Exis…
Autonomous Polycrystalline Material Decomposition for Hyperspectral Neutron Tomography
Mohammad Samin Nur Chowdhury, Diyu Yang, Shimin Tang +4
Hyperspectral neutron tomography is an effective method for analyzing crystalline material samples with complex compositions in a non-destructive manner. Since the counts in the hy…
TRINIDI: Time-of-Flight Resonance Imaging with Neutrons for Isotopic Density Inference
Thilo Balke, Alexander M. Long, Sven C. Vogel +2
Accurate reconstruction of 2D and 3D isotope densities is a desired capability with great potential impact in applications such as evaluation and development of next-generation nuc…
