Tomographic Model Based Iterative Reconstruction of Symmetric Objects
Kyle M. Champley, Ibrahim Oksuz, Matthew G. Bisbee +2
Computed Tomography (CT) reconstruction of objects with cylindrical symmetry can be performed with a single projection. When the measured rays are parallel, and the axis of symmetr…
Methods for Few-View CT Image Reconstruction
Kyle M. Champley, Michael B. Zellner, Joseph W. Tringe +1
Computed Tomography (CT) is an essential non-destructive three dimensional imaging modality used in medicine, security screening, and inspection of manufactured components. Typical…
Iterative Reconstruction of the Electron Density and Effective Atomic Number using a Non-Linear Forward Model
K. Aditya Mohan, Kyle M. Champley, Albert W. Reed +2
For material identification, characterization, and quantification, it is useful to estimate system-independent material properties that do not depend on the detailed specifications…
Dynamic CT Reconstruction from Limited Views with Implicit Neural Representations and Parametric Motion Fields
Albert W. Reed, Hyojin Kim, Rushil Anirudh +4
Reconstructing dynamic, time-varying scenes with computed tomography (4D-CT) is a challenging and ill-posed problem common to industrial and medical settings. Existing 4D-CT recons…
Extreme Few-view CT Reconstruction using Deep Inference
Hyojin Kim, Rushil Anirudh, K. Aditya Mohan +1
Reconstruction of few-view x-ray Computed Tomography (CT) data is a highly ill-posed problem. It is often used in applications that require low radiation dose in clinical CT, rapid…
Improving Limited Angle CT Reconstruction with a Robust GAN Prior
Rushil Anirudh, Hyojin Kim, Jayaraman J. Thiagarajan +2
Limited angle CT reconstruction is an under-determined linear inverse problem that requires appropriate regularization techniques to be solved. In this work we study how pre-traine…
