Estimating the spectrum in computed tomography via Kullback-Leibler divergence constrained optimization
Wooseok Ha, Emil Y. Sidky, Rina Foygel Barber +2
We study the problem of spectrum estimation from transmission data of a known phantom. The goal is to reconstruct an x-ray spectrum that can accurately model the x-ray transmission…

Few-view single photon emission computed tomography (SPECT) reconstruction based on a blurred piecewise constant object model
Paul A Wolf, Jakob H Jørgensen, Taly G Schmidt +1
A sparsity-exploiting algorithm intended for few-view Single Photon Emission Computed Tomography (SPECT) reconstruction is proposed and characterized. The algorithm models the obje…
