Fig. 3From: Reduction of metal artifacts from knee tumor prostheses on CT images: value of the single energy metal artifact reduction (SEMAR) algorithmThe absolute measurement error and the noise (standard deviation) of the CT numbers in the ROIs (marked in Fig. 1) in CT images at the stem level and articular level of the phantom. The values are shown for the different reconstruction settings: soft/sharper kernel and non-SEMAR/SEMAR reconstructionBack to article page
