摘要: Magnetic resonance imaging apparatus uses an array of at least two receive coils 4,5 to perform parallel processing enable phase-encode gradients be omitted during data collection, and restored using further reduce patient time in the apparatus, pre-acquired reference is used (modules 10, 11) unfold aliased target modules 8,9. In accordance with invention, unfolding performed against a series representations data, varied for translational rotational coil loading errors, unfolded image chosen as that having minimum entropy.
