제목: A resistive network for a conductivity recovery
연사: 김용정 교수
요약: In this talk we introduce a direct method to recover a static conductivity image from internal current data. The domain of the consideration is approximated by electrical circuits and a direct method to recover the conductivity image is constructed using the Kirchhoff’s law of currents. Hence this approach has a different structure from the ones
based on the finite difference or finite element. Magnetic resonance electrical impedance
tomography has been developed to obtain conductivity images with high resolution and
its method is based on an iterative scheme. The uniqueness of the limit has been
obtained in Kim et al without obtaining the convergence nor the stability. We will show
that the direct method in this paper has such properties. Numerical examples are give for various cases in two and three dimensions.
