TU‐FF‐A4‐02: Impact of Sinogram Modeling Inaccuracies On Image Quality in X‐Ray CT Imaging Using the Alternating Minimization Algorithm

Purpose: To provide a scientific basis for setting sinogram modeling accuracy targets based on impact of such errors on image quality. Modeling inaccuracies in photon spectrum and scatter distribution assumed by statistical image reconstruction (SIR) algorithms lead to systematic image artifacts. Me...
