In an embodiment, a parallel imaging method using cyclic matrices for medical imaging systems, exploits fundamental properties of the linear algebra of parallel imaging. Accordingly, the method provides an improved SMASH parallel imaging technique that overcomes some of the drawbacks of existing SMASH techniques, including long reconstruction time and degraded image quality due to uncorrected aliasing. In particular, this invention provides a SMASH technique with fast reconstruction times that are comparable to GEM, AUTO-SMASH, VD-AUTOSMASH and GRAPPA, but with better approximations for the reconstruction algorithm, resulting in better image quality.
