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

Figure 5

Comparison of the reconstruction results with different methods on the second cardiac dataset. The number of radial trajectory is 74 and 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).
