1. A computer-implemented method for performing multi-band slice accelerated imaging, the method comprising: performing a low-resolution fast multi-dimensional reference scan to obtain a coil sensitivity map; receiving an indication of a desired Field Of View (“FOV”) shift, determining a desired gradient moment for phase modulation to achieve the desired FOV shift; performing a multiband imaging scan to acquire a plurality of k-space lines representative of an anatomical area of interest, wherein balanced slice-selective gradients are used for phase modulation of each k-space line according to the desired gradient moment; separating a multi-band signal corresponding to the plurality of k-space lines into a plurality of image slices using a parallel imaging reconstruction technique and the coil sensitivity map.
