摘要： Disclosed is an image reconfiguration method for electro-magnetic tomography. The image reconfiguration method for electro-magnetic tomography includes: measuring electric field values of each electro-magnetic wave for normal tissue, benign tumor tissue, and cancer tissue that are body tissue properties to perform signal processing on the electric field values of the electro-magnetic waves; calculating the electric field values of the electro-magnetic waves that are subjected to the signal processing as specific image reconfiguration data values; and comparing with the calculated specific image reconfiguration data value and applying to a nonlinear image transform function to convert into amplified image output data value, thereby outputting an image based on the image output data value, wherein the nonlinear image transform function is an exponential function or log function based nonlinear image transform function that selectively amplifies only a difference in the specific image reconfiguration data values between the body tissues.
