Abstract

A computer-implemented method for performing multi-band slice accelerated imaging includes performing a low-resolution fast multi-dimensional reference scan to obtain a coil sensitivity map. A multiband imaging scan is performed to acquire a plurality of k-space lines representative of an anatomical area of interest. A multi-band signal corresponding to the plurality of k-space lines is separated into a plurality of image slices using a parallel imaging reconstruction technique and the coil sensitivity map.
