Larisa Beilina - Application of an adaptive finite element method in monitoring of hyperthermia

This talk was part of the of the online workshop on "Tomographic Reconstructions and their Startling Applications" held March 15 - 25, 2021.

In this talk will be presented an adaptive finite element method for solution of a linear Fredholm integral equation of the first kind. A posteriori error estimates in the functional to be minimized, and in the regularized solution to this functional, will be derived and corresponding adaptive finite element algorithms will be formulated. Balancing principle for optimal choice of the regularization parameter will be also discussed.

Finally, numerical experiments will show the efficiency of a an adaptive finite element method applied to data measured in microwave thermometry. The data is provided by a group of Biomedical Imaging (M. Aram, H. Dobsicek-Trefna) at the Department of Electrical Engineering at Chalmers, Gothenburg, Sweden, which works on the development of systems for hyperthermia treatment of deep-seated cancerous tumors using microwave thermometry.
