Abstract
Hyperthermia or heat therapy is emerging as a powerful modality in the fight against cancer, especially when it is used as an adjuvant to conventional radiation or chemotherapy treatments. However, the main challenge in hyperthermia treatment is the accurate targeting of the tumor area, and this project is focused on improving the efficiency of hyperthermia systems by the use of focusing structures. The heating is actually concentrated through the use of fabricated metal structures in shape of a cone or a cylinder, which are appended to the 27 MHz Mettler diathermy system. The heating effectiveness is measured, using a digital thermometer on a Absorber surface whose electrical properties are identical to the biological human tissue. Several heating studies were carried out to evaluate the effects of using the focusing structures, and will be detailed in the report.
