Estimation of kinetic model parameters in fluorescence optical diffusion tomography

J Opt Soc Am A Opt Image Sci Vis. 2005 Jul;22(7):1357-68. doi: 10.1364/josaa.22.001357.

Abstract

We present a technique for reconstructing the spatially dependent dynamics of a fluorescent contrast agent in turbid media. The dynamic behavior is described by linear and nonlinear parameters of a compartmental model or some other model with a deterministic functional form. The method extends our previous work in fluorescence optical diffusion tomography by parametrically reconstructing the time-dependent fluorescent yield. The reconstruction uses a Bayesian framework and parametric iterative coordinate descent optimization, which is closely related to Gauss-Seidel methods. We demonstrate the method with a simulation study.
