NORMALIZED-CONSTRAINT ALGORITHM FOR MINIMIZING INTER-PARAMETER CROSSTALK IN IMAGING OF SCATTERING MEDIA

摘要

A method and system for minimizing inter-coefficient crosstalk in imaging the internal properties of a scattering medium. The method and system minimizing inter-coefficient crosstalk in image reconstruction by solving a system of linear perturbation equations with the use of relative detector values, weight matrix scaling, and constraints based on either the known or unknown direction of the perturbations in the medium's properties. The constraint being either (1) positive or negative corresponding to the direction of a known perturbations, or (2) solving the system of equations with both positivity and negativity constraints and summing the results when the direction of the perturbations are unknown. The advantages of the inventive method and system result in effective isolation of absorption and scattering coefficient variations, even for complex combinations of perturbations in these coefficients.
