MRI Reconstruction with Separate Magnitude and Phase Priors Based on Dual-Tree Complex Wavelet Transform

Figure 1

The (a) magnitude and (f) phase images are reconstructed directly from a full-sampled -space brain dataset. Under 33% subsampling rate, the magnitude reconstruction results are shown in the upper row, respectively, by (b) FISTA, (c) ADMM, (d) SD [39], and (e) pFISTA [11]. And the below row displays the corresponding magnitude error maps of (g) FISTA, (c) ADMM, (d) SD, and (e) pFISTA.
