Synchronized multiartifact reduction with tomographic reconstruction (SMART‐RECON): A statistical model based iterative image reconstruction method to eliminate limited‐view artifacts and to mitigate the temporal‐average artifacts in time‐resolved CT

Purpose: In x‐ray computed tomography (CT), a violation of the Tuy data sufficiency condition leads to limited‐view artifacts. In some applications, it is desirable to use data corresponding to a narrow temporal window to reconstruct images with reduced temporal‐average artifacts. However, the need...
