Bioelectromagnetics is an emerging field in electromagnetic medical therapy research. It mainly focuses on the interaction between the electromagnetic field and biological entities, such as living cells, tissues or organisms. It has been claimed that the illuminating by electromagnetic field can cause thermal and behavioral effects on biological units. Moreover, certain biological unit itself also generate subtle electromagnetic fields. Examples include the cell membrane potential and the electric currents that flow in nerves and muscles, as a result of action potentials. Due to these interesting, yet unclear phenomena, the study of bioelectromagnetics has become increasingly popular during the recent years. However, most physical experiments in this area must be performed based on living units. Consequently it is sometimes quite risky and expensive to carry out direct experiments especially for those tests on human bodies. Because of this, the ability to model and simulate the electromagnetic effects on living biological entity via virtual computer simulation techniques become important.
The challenge in simulating EM effects on biological units resides in the complexity of material definition. Since the living unit usually can not be easily measured for its EM material property, the data is often obtained by 3D scanning measurements, such as MRI or X-ray. Such data describes the material information through discretized volume pixels (Voxel). Wavenology EM has been designed to directly use the voxel data obtained directly from measurement. An example of the human breast illuminated by a electromagnetic dipole is demonstrated below.
