Abstract :
Microwave technology is now widely used in a variety of medical applications such as cancer treatment and diagnostics. This paper describes the structure of a novel hyperthermia system for biomedical research. The software Ansoft HFSS was used to design a rectangular waveguide applicator. A closed-loop is presented in order to control the output power of the system by the temperature measured on the sample. Initial results from experimental testing are presented. In these results, it is shown that the water temperature can be increased from 21°C to 40°C in 12 minutes. As a result, it has been tested that the system works properly. The next step will be to apply the system to melanoma cancer cells.
