Biologic physics character of radio-frequency and its application on tumour therapy

In this paper, based on the biologic physics characters of radio-frequency, we design a hyperthermia instrument, which uses FPGA to serve as controller and signal generator, utilizes three-electrode capacitive RF hyperthermia to adjust heating field distribution, and realizes multipoint temperature measure by a decaying fluorescence type fiber optical sensor. The therapy result on brain glioma is also presented.
