| Abstract | Inter-slice shift is one of the most important factors for reducing g-factor in multi-band (MB) simultaneous multi-slice acquisition. Previous study1 has shown that the optimal distance of slice shift can deviate away from intuitive choices such as FOV/Nslice However, optimizing shift pattern is time-consuming because iterative algorithms have to be used. In this study, we propose a fast g-factor estimation model that can approximately estimate g-factor versus slice shift distance with closed form formula, with input of slice number and one parameter quantifying the coil sensitivity in slice direction. |
