Radiological hypertermia with microwaves and radio-frequencies.I. Multifrequency generator system presentation

A computerized system with automatic treatment parameters control for radiological hyperthermia, called Sapic SVO3,is presented.The system has been planned and built by the ''Sezione Avionica ed Equipaggiamenti'' of the Aeritalia in cooperation with the Radiotherapy Department of the University of Turin.The device is supplied with a multifrequency genera tor system (915,433,2-30 MHz) connected with many kinds of applicators (microstrip antennas, high constant dieletric material loaded antennas, waveguide antennas),with a fiber optic system for temperature control and with a previsional thermometry system
