1. A method for eccentricity correction comprising:
disposing a downhole tool into a borehole, wherein the downhole tool comprises a measuring assembly having at least one transducer;
determining a beam pattern and a beam pattern factor from the at least one transducer;
determining a center of the measurement assembly in the borehole with the beam pattern;
calculating an angle factor with at least a radius of the borehole;
calculating an eccentricity factor with at least the beam pattern factor and the angle factor; and
creating an eccentricity corrected image based at least on the eccentricity factor.
