Abstract (en)

An extracorporeal ultra-high-speed ultrasound hyperthermia treatment method consisting in transmitting and focussing on the tumor ultrasound wave trains at frequencies between 0.5 and 10 MHz with peak electric powers which may reach 20 Kw or more, the parameters which define the concentration of the treatment beam in the focal spot and the power being determined so that, irrespective of the depth and the nature of the tissue, the treatment time is in the order of that enabling significant destruction, preferably total destruction, of the target during the linear part of a curve showing the temperature increase as a function of time. <IMAGE>
