Clinically used heating techniques involve electromagnetic and ultrasonic heating, hyperthermic perfusion and conductive heating.
These vary considerably in technique, heating depth, ability to focus, and in the size of the heating focus. Several types of devices, antennas and heating or power delivery systems have been proposed and developed in recent decades. Achievement of an effective treatment requires high quality heating equipment, precise thermal dosimetry, and adequate quality assurance. heating to 39–45☌ to induce sensitization to radiotherapy and chemotherapy, and thermal ablation, where temperatures beyond 50☌ destroy tumor cells directly are frequently applied in the clinic. The therapeutic application of heat is very effective in cancer treatment.
