Claim One:
1. A system for identifying spatially and temporally distributed phase deviations within a sample under evaluation, comprising: a magnetic resonance imaging machine including a birdcage coil and a magnetic resonance machine radio frequency generator, wherein the magnetic resonance imaging machine applies a main magnetic field to the sample under evaluation within the magnetic resonance imaging machine, and wherein the birdcage coil comprises a plurality of orthogonal coil sets each comprising a coil B and a coil A, wherein an angle α between each coil B of the plurality and an axis orthogonal to the main magnetic field is different; an induction component configured to induce spatially and temporally ordered phase deviations of the transverse magnetization within the sample under evaluation; a computer system connected to the magnetic resonance imaging machine, wherein the computer system is configured to: receive a first voltage from a coil A of one of the orthogonal coil sets of the plurality; receive a second voltage from a coil B of the one of the orthogonal coils of the plurality; receive an output of the magnetic resonance machine radio frequency generator and phase-shift the output to a first and second phase-shifted voltage; multiply the first voltage by the first phase-shifted voltage to generate a first result; multiply the second voltage by the second phase-shifted voltage to generate a second result; sum the first and second results to generate a spatial Fourier transform of a Feature Space representing an original native data set of the sample under evaluation produced by the magnetic resonance imaging machine without the induction of the spatially and temporally ordered phase deviations; apply an inverse Fourier Transform to the spatial Fourier transform of the Feature Space representing the original native data set to generate a Feature Space which is the original native data set; multiply the first voltage by the second phase-shifted voltage to generate a third result; multiply the second voltage by the first phase-shifted voltage and invert the result to generate a fourth result; sum the third and fourth results to generate a spatial Fourier transform of an Aberrational Feature Space representing the product everywhere of the original native data set and the induced spatially and temporally ordered phase deviations; apply a deconvolution algorithm to the spatial Fourier transform of the Aberrational Feature Space and the spatial Fourier transform of the Feature Space to generate a fifth result; apply an inverse Fourier Transform to the fifth result to generate a Phase Aberration Space which is the data set of the spatially and temporally ordered phase deviations; generate at least one image using the Feature Space which is the original native data set; and generate at least one image using the Phase Aberration Space.
