1. A method for determining one or more properties of a tissue, comprising:
exciting a tissue with an excitation energy from an excitation source at an excitation frequency;
acquiring a set of images of the tissue from an imaging device;
performing a Fourier Transformation on the set of images to generate a set of phasor coordinates;
computing a D-trajectory of the phasor coordinates;
computing a set of values of additional parameters selected from the group consisting of coordinates for a center of mass g and s, second axial moments a and b after diagonalization, an angle of distribution from diagonalization, and a total number of pixels in the phasor plot from slices derived from the phasor coordinates from the set of images and the phasor coordinates;
comparing the set of values to a set of stored values related to tissues having one or more known characteristics; and
calculating one or more properties of the tissue from the set of values and the set of stored values.
