Sparse Constrained Reconstruction for Accelerating Parallel Imaging Based on Variable Splitting Method
Figure 4
Reconstructed images from noisy undersampling MR data for in vivo parallel MRI, where the undersampling rate is 8, which is the maximum at theory. (a) is the reference image (SoS reconstruction of full-sampled coil images). (b), (c), and (d) are images reconstructed, respectively, by GEM method, CG method, and the proposed method proposed as (9). (e) is the reconstructed image by SoS method. (f), (g), and (h) are the difference profiles, respectively, between (b), (c), (d), and (a).
