Abstract:
1. A magnetic resonance (MR) system comprising: a driving module configured to apply a perturbation to a sample; a processor configured to generate RF modulated pulses, the RF modulated pulses configured to define a plurality of at least three different rotating frames of reference relative to the perturbation, the plurality of at least three different rotating frames of reference including at least two frames in which each frame of the at least two frames includes a fictitious field and wherein at least one fictitious field is time variant, the fictitious fields are produced by an interaction of the plurality of the at least three different rotating frames of reference, and each different rotating frame is associated with an effective field, wherein the fictitious fields and the effective fields are associated with the generated modulated pulses and the modulated pulses are produced by a recursive expansion; and a readout module coupled to the processor and configured to generate an output based on a relaxation of spins of the sample as a function of the perturbation in order to display or store a magnetic resonance output with the readout module.
