Characterization and identification of spatial artifacts during 4D-CT imaging

By Dongfeng Han, John Bayouth, Sudershan Bhatia, Milan Sonka and Xiaodong Wu


Purpose: The purpose of this work is twofold: First, to characterize the artifacts occurring in helical 4D-CT imaging; second, to propose a method that can automatically identify the artifacts in 4D-CT images. The authors have designed a process that can automatically identify the artifacts in 4D-CT images, which may be invaluable in quantifying the quality of 4D-CT images and reducing the artifacts from the reconstructed images on a large dataset
