Hyperthermia is presently used as an adjuvant to the radiation therapy in the treatment of certain types of cancers. Recently, many randomised trials have shown a significant advantage of addition of hyperthermia combined with radiotherapy and/or chemotherapy in the treatment of solid tumours. This paper presents the first experimental results obtained with a prototype of a new system for microwave hyperthermia based on time-reversal algorithm. The level of absorbed energy is strongly dependent on size of treated area through penetration depth of EM waves, thus selection of the frequency depends on treated area sizes as well as tumour volume. The system has thus been designed to work at broad frequency range.
