Bio-Electromagnetic simulation for improved medical imaging

To avoid the application of ionizing radiation to the human body, microwave based imaging has become a topic of intensive research over the last years. This presentation will introduce and compare two major approaches in this domain: Ultra-Highfield Magnetic Resonance Imaging is based on the nuclear spin response, while Microwave Imaging applies ideas of radar arrays to medical imaging. Both approaches have in common that they are based on complex multi-channel antenna structures. Bio-Electromagnetic simulations are a key design tool for developing these devices, both to ensure their technical functionality, as well as to understand safety aspects inside the human body which are still difficult to assess by measurement.
