SU‐F‐500‐03: Modeling Nonstationary Noise and Task‐Based Detectability in CT Images Computed by Filtered Backprojection and Model‐Based Iterative Reconstruction

Purpose: Nonstationarity of noise poses a major challenge to the modeling and optimization of CT imaging systems, particularly those employing iterative reconstruction. This work presents theoretical models for the spatially varying noise and spatial resolution properties of filtered‐backprojection...
