| Outline of Final Research Achievements |
This project is aimed at innovation of the diffused optical tomography(DOT) from the view point of mathematical science, and DOT is consideredas an inverse problem to detect unknown coefficients in the radiative transport equation (RTE). There are two approaches to the inverse problem;the one is based on time resolution data as observation, and the other is based on stationary data. We obtained prominent result for the former case,and we focus on discontinuity of the coefficients as to show nice images numerically through reconstruction of the coefficients having discontinuity.We also prove convergence of the CIP (Cubic Interpolation Pseudoparticle) method to solve hyperbolic partial differential equations, which is used in our numerical simulation, to give an affirmative answer to an open problem about the CIP scheme. We propose new idea on iteration approach to the latter case, and we show new effective algorithm for numerical
simulation of the stationary RTE.
