Detailed information about the electrophysical behaviour of the heart can be obtained by measuring electrical potentials in combination with the position of the measurement electrodes and the conductivity distribution in the body. This study describes a less expensive approach to create a model of a human thorax, and thus, the conductivity distribution. In a preprocessing step, a rigid electrod...

A two-pronged approach, review and measurement, has been adopted to characterize the conductivity of tissues at frequencies below 1 MHz. The review covers data published in the last decade and earlier data not included in recent reviews. The measurements were carried out on pig tissue, in vivo, and pig body fluids in vitro. Conductivity data have been obtained for skeletal and myocardial muscle...

We consider magnetic resonance electrical impedance tomography, which aims to reconstruct the conductivity distribution using the internal current density furnished by magnetic resonance imaging. We show the uniqueness of the conductivity reconstruction with one measurement imposing the Dirichlet boundary condition. And we propose a fast non-iterative numerical algorithm for the conductivity re...

The effects of field strength and multiple thermal treatments on electrical conductivity of strawberry products were investigated. Electrical conductivity increased with temperature for all the products and conditions tested following linear relations. Electrical conductivity was found to depend on the strawberry-based product. An increase of electrical conductivity with field strength was obvi...
