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; performing a multiband imaging scan to acquire a plurality of k-space lines representative of an anatomical area of interest; 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.
