Improved - PCA Algorithm Using Artificial Sparsity in Dynamic MRI

Figure 6

Summary of the quantitative performance of three - PCA methods on numerical simulations. The plots show the NRMSE of different time frames of 4-fold acceleration (a), -NRMSE of different reduction factors (b), and the signal-intensity time courses of left ventricle (d) and right ventricle (c) at the reduction factor of 4 with different time frames.
