Medical applications of high-frequency electromagnetic fields

The group studies medical applications of high frequency electromagnetic fields, e.g., microwave thermal ablation. Conducted studies include dosimetry of electromagnetic fields, microwave thermal ablation, hyperthermia, tissue dielectric properties characterization, as well as microwave imaging. As an example, studies are conducted to experimentally determine the dependence of dielectric and thermal properties on the temperature, and to develop numerical models representative of the electromagnetic field and temperature evolution in microwave thermal ablation procedures.

Microwave thermal ablation. Effects of tissue properties variations on predictive models for treatment planning

Microwave thermal ablation (MTA) therapy for cancer treatments relies on the absorption of electromag- netic energy at microwave frequencies to induce a very high and localized temperature increase, which causes an irreversible thermal damage in the target zone. Treatment planning in MTA is based on exper- imental observations of ablation zones in ex vivo tissue, while predicting the treatment outcomes could be greatly improved by reliable numerical models.
