Abstract
This project will focus on the methods of improving the heating effects of 27.12 MHz Mettler Diathermy system by using reflector networks, for potential use in Hyperthermia systems for the treatment of cancer. Currently, the Mettler system is tested by heating wet absorber material, which is chosen since its electrical properties are identical to the biological human tissue. However, previous studies using the same system have showed that the applicator needs to be very close to the heating surface, to obtain any significant increase in temperature; additionally, the surface also requires to be heating for at least 60 minutes to increase the temperature by 10-15 degrees. The aim of the current study is to study any possible increase in efficiency, by using different types of reflector networks, which are metallic structures that help to focus the RF energy from the Mettler source. Our goal would be to achieve the temperature of the treatment within the desired time, while maintaining a suitable distance between applicator and treatment surface.
