Figure 10.

Effect of ADMIRE and NiTANN on SD of the density distribution of air insert (upper left), emphysema material (upper right), lung material (lower left) and water (lower right). Only soft kernel scans were used for these plots; hard kernels showed similar results, but with a wider range of SD values. The black line shows the equality line, so SD values to the right of the line are lower in the processed scan than in the unprocessed scan. ADMIRE, ADvanced Model Iterative Reconstruction; NiTANN, non-iterative technique artificial neural network; SD, standard deviation.
