Microwave hyperthermia treatment system

A microwave hyperthermia treatment system comprising:

• a set of microwave emitters positionable about a patient;
• a radiofrequency power source connected to the microwave emitters to provide radiofrequency power having independently controllable amplitude and phase for each microwave emitter;
• and
• a treatment controller connected to the radiofrequency power source controlling the phase and amplitude of the radiofrequency power for each microwave emitter to change the frequency and amplitude at the microwave emitters over a treatment time according to a treatment schedule determined and stored in non-transitory medium before application of power to the microwave emitters for treatment of the patient and executed by the treatment controller during application of power to the microwave emitters for treatment of the patient, wherein the treatment schedule provides a predetermined series of at least three sequentially applied power deposition patterns producing different patterns of heating of tissue of the patient within and outside of a tumor site so that radiofrequency power is concentrated within the tumor site;
• and
• wherein the power deposition patterns each provide different hotspots and suppression regions and wherein the treatment schedule matches predetermined hotspots of one power deposition pattern with predetermined suppression regions of another power deposition pattern to control and differentiate an average power deposition in the tissue region inside and outside the treatment region.
