Abstract

In this paper, we analyze the error resulting from the discretization of the forward and inverse problems in simultaneously reconstructed optical absorption and scattering images. Our analysis indicates the mutual dependence of the forward and inverse problems, the number of sources and detectors, their configuration and the location of optical heterogeneities with respect to sources and detectors affect the extent of the error in the reconstructed optical images resulting from discretization. One important implication of the error analysis is that poor discretization of one optical coefficient results in error in the other, resulting in inter-parameter "cross-talk" due entirely to discretization.
