Improved - PCA Algorithm Using Artificial Sparsity in Dynamic MRI

Figure 3

Results of numerical simulations with reduction factor of 4 using three different reconstruction methods. The 9th frame in the time sequence corresponds to Row 1, the 13th frame corresponds to Row 2 and the 25th frame corresponds to Row 3. The small figures in the left bottom corner of each figure demonstrate the corresponding enlarged region defined by the white box. The reconstructed images are shown in the same intensity scale. The reference images are reconstructed by directly applying FFT for fully sampled data.
