Modeling and Analysis of Bioimpedance Measurements

摘要

In this work we presented the technology for high-resolution efficient numerical modeling of bioimpedance measurements. This technology includes 3D image segmentation, adaptive unstructured tetra-hedral mesh generation, finite-element discretization, and the analysis of simulation data. High resolution anatomically correct model based on Visible Human Project data was created. Sensitivity field distributions for a Kubicek-like scheme, as well as two eight-electrode segmental torso measurement schemes were computed and compared. All presented methods and techniques are well-known and are implemented in several open-source packages.
