Claim One:
1. A system for identifying spatially and temporally distributed phase deviations within a sample under evaluation, comprising: a magnetic resonance machine including at least one quadrature coil set and a magnetic resonance machine radio frequency generator, wherein the magnetic resonance machine applies a main magnetic field to the sample under evaluation within the magnetic resonance machine; 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 machine, wherein the computer system is configured to: receive a first voltage from the at least one quadrature coil set; receive a second voltage from the at least one quadrature coil set; 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 and invert the result 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 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 to generate a fourth result; and 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; and 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.
