Electromagnetic fields
in diagnostics and therapy
The Bio-electromagnetism Research Group at the Department of Biomedical Technology, FBME CTU, studies the interaction of electromagnetic fields with biological tissue and its use in medical diagnostics and therapy. We develop methods for microwave hyperthermia and treatment planning, microwave imaging and non-invasive thermometry, measure the dielectric properties of tissues and numerically model the propagation of electromagnetic fields and heat in the human body. Our results are validated on phantoms and in clinical practice in cooperation with hospitals and industrial partners.

Tonagena
CTU spin-off
In 2023 the Bio-electromagnetism team founded an official CTU spin-off, Tonagena s.r.o., to commercialise the technologies and devices developed in the group. The team is involved in all aspects of bringing a product to market, from development and testing through certification to production and sales. The spin-off has commercialised the TonaPulse® system, including a unique electrode system for adherent cell cultures, which is used for example at the 3rd and 2nd Faculties of Medicine of Charles University for research on irreversible electroporation in the treatment of cardiac arrhythmias and on gene transfection.
Besides electroporation, Tonagena is involved in custom development of microwave applicators and radar solutions for significant local companies, where it has already delivered hardware in both areas.
