Joint System and Algorithm Design for Computationally Efficient Fan Beam Coded Aperture X-ray Coherent Scatter Imaging
Ikenna Odinaka, Joseph A. O'Sullivan, David G. Politte +8
In x-ray coherent scatter tomography, tomographic measurements of the forward scatter distribution are used to infer scatter densities within a volume. A radiopaque 2D pattern plac…
Spectrally Grouped Total Variation Reconstruction for Scatter Imaging Using ADMM
Ikenna Odinaka, Yan Kaganovsky, Joel A. Greenberg +5
We consider X-ray coherent scatter imaging, where the goal is to reconstruct momentum transfer profiles (spectral distributions) at each spatial location from multiplexed measureme…
Alternating Minimization Algorithm with Automatic Relevance Determination for Transmission Tomography under Poisson Noise
Yan Kaganovsky, Shaobo Han, Soysal Degirmenci +4
We propose a globally convergent alternating minimization (AM) algorithm for image reconstruction in transmission tomography, which extends automatic relevance determination (ARD)…
Non-Paraxial Wave Analysis of 3D Airy Beams
Y. Kaganovsky, E. Heyman
The 3D Airy beam (AiB) is thoroughly explored from a wave-theory point of view. We utilize the exact spectral integral for the AiB to derive local ray-based solutions that do not s…
