Volume Source and Volume Conductor

Show Summary Details


This chapter characterizes the nature of bioelectric sources and conductors. It points out that in contrast to electronic circuits, in which the electric properties of the components are concentrated, the biological organs are distributed volume sources and volume conductors. The standard equations describing the electric field of a volume source in a volume conductor are derived. The electric properties of the human body as a volume conductor are then characterized. This is followed by an introductory discussion of modeling of the biological volume sources and volume conductors. The fundamental concepts of forward and inverse problems are then defined and their solvability is discussed.

Keywords: volume conductors; bioelectric sources; electric field; forward problem; inverse problem; biological organs
