Title
Adjoint field methods for non-linear tomographic medical imaging problems
Abstract
We show results for full three-dimensional nonlinear inver- sion of the parameters of a diffusive partial differential equa- tion, specifically for an optical tomography application. We compute functional derivatives of the parameters with re- spect to the mean-squared error using the adjoint field me- thod, and implement two forms of regularization. In the first, a penalty term is introduced into the error functional, and in the second, the solution to the inverse problem is as- sumed to belong to a parametrized class of functions. In the case where this assumption is correct, our results demon- strate that the parameters can recovered with high accu- racy, yielding a better inversion result than the traditional Tikhonov-type approach.
