Abstract

Systems and methods are provided for acquiring imaging data from one or more resonance species that simultaneously produce individual magnetic resonance signals in a plurality of different slices. The data is acquired by simultaneously exciting, using a pTX RF coil array, a plurality of different slices such that at least some of the plurality of different slices are excited by transmitting RF energy from a subset of transmit channels in the pTX RF coil array. The method also includes comparing the data to a dictionary of signal evolutions to determine quantitative values for two or more parameters of the resonant species based, at least in part, on matching the data to a set of known signal evolutions stored in the dictionary. The method includes producing an image for each of the plurality of different slice locations, at least in part, on the quantitative values.
