Claim Text:
1. A method of generating magnetic resonance images of an q-dimensional object using a magnetic resonance imaging (MRI) system having a subsystem generating a number of m of spatial encoding magnetic fields (SEMs) to encode an excited magnetization and a receiver coil array of a number of p of receiver coils for detecting the excited magnetization, comprising the steps of: a) choosing, from the generated SEMs, at least one SEMs having moronically field strength and direction distributions or non-monotonically field strength and direction distributions within a selected field-of-view (FOV); b) determining, for each of the chosen SEMs, a corresponding spatial basis from the rise time, duration, and ramp-down time of the chosen SEM; and c) reconstructing an image of the q-dimensional object based on the data points obtained at each of the receiver coils at each of the spatial bases; wherein the generated SEMs include one of SEMs that are spatially bijective, SEMs that are non-bijective, and the combination thereof within the selected FOV, with m being equal to or larger than q, and wherein the receiver coils have a number of spatially distinct sensitivity maps which is equal to or less than p.
