Bioimpedance and Bioelectricity Basics, 3rd Edition

Chapter 6

Geometrical Analysis

Abstract

This chapter deals with how geometrical factors influence on how electrical signals are transferred in biomaterials or how different parts of a measured volume contribute, for example, to the measured impedance. The concept of sensitivity field distribution is described and numerical analysis such as the finite element method is introduced. An overview of electrical impedance tomography is also given.

Important electrical characteristics of an electrode/tissue system are determined solely by the geometrical configuration. To clarify this important function, the systems to be treated in Chapter 6 are simple models suited for basic ...
