Claim One:
1. A method of multinary inversion for imaging of physical properties of an examined medium characterized by discrete physical property values, the method comprising: a. placing a data acquisition system in proximity of a target area of the examined medium, and acquiring and processing observed data related to the target area; b. selecting a multinary function that accepts a finite number of discrete values from physical property values of the target area, and which characterizes a set of discrete values of the physical properties of the target area; c. emulating the data acquisition system and its parameters by a forward modeling calculation of predicted data related to the target area; d. calculating a misfit functional and a residual vector between the observed data and the predicted data; e. calculating stabilizing functionals for model parameters and calculating Fréchet derivatives (sensitivities) of the observed data with respect to the multinary model parameters; f. solving a multinary inverse problem by minimizing a parametric functional formed by a linear combination of the misfit and stabilizing functionals; g. evaluating termination criteria of the multinary inverse problem; and h. calculating physical property values to produce intermediate and/or final images of the examined medium.
