Intersubject comparison. For subject 1, (a) shows a representative reference image from SENSE reconstruction, (b) shows the corresponding CS reconstruction for each CS reconstruction using AF = 5, and (c) shows the nRMSE for the corresponding technique. Similarly, for subject 2, (d) is the reference image, (e) is CS reconstruction at AF = 5, and (f) shows the nRMSE for each technique at AF = 5.
