ROIs in the CT images of phantom. ROIs were placed 3 cm form the prosthesis and kept consistent on non-SEMAR images and SEMAR images. At the stem level (a ~ d) and articular level (e ~ h), axial non-SEMAR image with soft kernel (a, e) and sharper kernel (c, g) reveals prominent, sharp, streak artifacts, while axial SEMAR image with soft kernel (b, f) and sharper kernel (d, h) demonstrating markedly reduced artifacts
