Estimating the spectrum in computed tomography via Kullback–Leibler divergence constrained optimization
PURPOSE: 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 curves and reflects a realistic shape of the typical energy spectra of the CT system. METHODS: Spectrum estima...
