NUMERICAL SIMULATION OF LOW-FREQUENCY CURRENT DENSITY DISTRIBUTIONS IN VOXEL-BASED HUMAN ANATOMY MODELS DUE TO AMBIENT ELECTRIC AND MAGNETIC FIELDS

摘要

Ambient extremely low-frequency magnetic and electric high voltage fields are the cause of electric current density distributions caused in human body tissues. For both problems, formulations based on the matrix formalism of the Finite Integration Technique are presented which are related to the standard scalar-potential finite difference (SPFD) approach. Numerical simulations for both types of quasistatic field exposure are presented using a high-resolution voxel-based 3D anatomy model.
