| Outline of Final Research Achievements |
In most MR scanning, image reconstruction is executed by taking the inverse Fourier transform of acquired signal. However, image reconstruction in compressed sensing requires the choice of sparsifying transform function and algorithms for L1 minimization of cost function, therefore, the obtained image quality depends on those functions and reconstruction algorithms. In this research, comparison of iterative shrinkage algorithm and ADMM (Alternating Direction Method of Multipliers) in compressed sensing of phase-varied MR images was performed. Experimental studies showed that the highest PSNR was obtained in ADMM combined with multi-scale sparsifying transform function.
