摘要：
The effect of metal artifact reduction algorithms on CT image quality was considered. The mean signal intensities and noise levels were compared for objects with different X-ray densities and spatial positions using phantom modeling. It was shown that, despite an improvement in the visual characteristics of the images, their quantitative characteristics may deteriorate: the change in the mean density reached in some cases 15%; the increase in noise, 30%.
