Therefore, utilizing the difference of impedance with tumour and normal tissue is our research development goal. Utilize this principle to focus the electric current on the cancer cell to enhance heating temperature difference, it will make the tumour necrosised and reduce the injury in normal tissue around the tumour. High frequency thermotherapy system provides excellent impedance matching under 500K Hz of the frequency and possess functions for temperature monitoring and file saving. The system also provides enough output power to heat the solution which meets the requirements for the heating experiment. The variation trend in solution impedance is similar with that measured on tissue.
