Iterative
susceptibility reconstructions requires four Fast Fourier Transforms in every
iteration and hundreds of iterations to converge. Although the iteration is
hard to disperse, FFT can be computed in parallel. In this study, a
parallelized FFT based on OpenMP was implemented to achieve quasi real-time
susceptibility map reconstructions.
