Abstract
There is featured a method for parallel spatial encoding MR image data that is frequency-encoded and sensitivity-encoded that includes applying an analytical transform function to generate weighting coefficients for a given spatial harmonic order and detector index; generating linear combinations of the frequency-encoded and sensitivity-encoded MR image data to generate a set of spatial harmonics that can encode spatial frequencies; and applying at least a 1D Fourier transform to a k-space data set in which spatial frequency dimensions are fully encoded, thereby resulting in. an MR image of an observed object. The method includes synchronizing the MR image data signals to remove spatially-dependent phase errors using for example Fourier-Hilbert Transforms. The method yet further includes demodulating the modulation of generated high order harmonics. Also featured are systems, apparatuses and other processing methods.
