Low-Rank and Sparse Decomposition Model for Accelerating Dynamic MRI Reconstruction

Figure 2

Comparison of the reconstruction results with different methods on the first cardiac dataset. The acceleration rate is 4 or sampling ratio is about 0.25. Fully sampled image (a) and undersampling mask (b), undersampled by zero-filled directly (c), reconstructions using k-t RPCA (e), k-t SLR (g), and proposed method (i) with their respective residuals (d, f, h, j).
