Super-Resolution of Magnetic Resonance Images via Convex Optimization with Local and Global Prior Regularization and Spectrum Fitting

Figure 7

Reconstructed images of the brain phantom. Top three rows show illustrations of axial cross-sections, zoomed sagittal cross-sections, and the Fourier spectra of the T1-weighted brain without lesion (data (c)). The next three rows show those of the T2-weighted brain without lesion (data (k)), and the bottom rows show those of the T2-weighted brain with lesion (data (o)). and the noise level was for the observation settings.
