Abstract:
A method for magnetic resonance imaging comprising the steps of:(a) exciting nuclear spins in an interconnected region of a subject, and thereby causing radio frequency response signals to be emitted from said region; (b) receiving said radio frequency response signals simultaneously with each of a plurality of component coils, each of said component coils having a characteristic sensitivity over said region defined for at least one spin excitation, and thereby obtaining a plurality of received radio frequency response signals; (c) forming a plurality of different signal combinations from said plurality of received radio frequency response signals dependent on combinations of the respective characteristic sensitivities of said component coils, with each of said signal combinations represented as a term equated with a signal having an alternating component that can be periodically expanded and then presented in a series having sensitivity coefficients; (d) forming an ordered dataset from said signal combinations of at least one spin excitation by solving a linear system of equations given by the sensitivity coefficients of the respective series and the term of the associated signal combination; and (e) spatially transforming said ordered dataset to generate a magnetic resonance image of said region.
