The generic (scientific) name of Oncothermia is modulated electro-hyperthermia (mEHT). It is a further development of the heating method, heating selectively the malignant cells instead of the complete isothermal heating of the tumor-mass.
Modulated electro-hyperthermia (mEHT, trade name: oncothermia) is an emerging curative treatment method in this field due to its highly selective actions. The impedance-matched, capacitive-coupled modulated radiofrequency (RF) current is selectively focused in the malignant cell membrane of the cancer cells.
