Abstract
In this paper the problem of enhancement of low-dose CT scans was considered. In particular, popular pre-processing algorithms (such as anisotropic diffusion filter, non-local means filter, mean-shift filter) were tested and analyzed. The assessment of image quality improvement was performed based on the artificially generated artifacts, similar to those appearing in low-dose CT scans . Their effectiveness was investigated using the image quality measures, such as the mean square error and the structural similarity index.
