FIG. 6

Simulated phantom experiments showing robustness to incorrect lipid mask selection: (a) Reconstructed NAA maps are shown in the first row whereas the corresponding lipid masks and lipid maps are shown in the second and third row, respectively. The NAA maps are of comparable quality. The lipid leakage reduces slightly for an overestimated/wide mask. Only the metabolite region is shown in the lipid maps for better visualization of differences. (b) The spectra at five representative locations shown in the reference image are plotted. The lipid leakage and denoising is comparable even for incorrect mask estimation. However, a wide mask might show improvement in lipid suppression. It is to be noted that the reconstructions with ideal mask (second column) is same as reconstruction with proposed method as in Figure 5b and d. The metabolite mask used in all the simulations is same.
