Abstract:
A method for producing an image of a subject with a magnetic resonance imaging (MRI) system is provided. In particular, spatial encoding of signals received from the subject is performed by spatial encoding magnetic fields (SEMs) produced by driving a parallel array of local gradient coils with current weightings that define a mode of the coil array. A set of globally orthogonal modes are determined using a singular value decomposition and two modes that produce SEMs with desired magnetic field variance characteristics are selected for spatial encoding. The spatially encoding signals are received by a parallel array of radio frequency receiver coil elements in order to resolve ambiguities in spatial encoding caused by the SEMs. Images are subsequently reconstructed using, for example, an iterative time domain reconstruction method.
