A magnetic resonance image is formed by measuring RF signals in an array of RF coils, forming a set of spatial harmonics and tailoring the set of spatial harmonics to form a set of tailored spatial harmonics that are adjusted variations in at least one of angulation of an image plane, field of view, a nd coils sensitivity calibration. The magnetic resonance image may also be form ed by generating a set of encoding functions representative a spatial distribution of receiver coil sensitivities and spatial modulations corresponding to the gradient encoding steps, transforming the set of encodi ng functions to generate a new set of functions representative of distinct spatial positions in the image, and applying the new set of functions to a s et of MR signals to form the magnetic resonance image. Matrices inverted during the process of forming the magnetic resonance image may be conditioned by thresholding the eigenvalues of the matrix prior to inversion.
