RESUMO
In the 40 years of last centry American scientists put forward a concep of high intensity focused ultrasound (HIFU) therapeutic technique and had done some technical and clinical studies. Since 90 years the HIFU surgery technique treating tumors anew rised abruptly in the world. China firstly put out a comprehensive HIFU tumor treating sistem and successfully treated many solid tumors such as breast cancer, bone tumor, liver cancer etc.. Now the treating sistem has already exported to England, Italy,Spain, Japan, Colea etc. and treated tens thousands tumor patients. In the field of noninvasive ultrasound treating tumor technique China has continually kept the leading position in the world.
RESUMO
High intensity focused ultrasound (HIFU) is a novel physical tumor therapeutic technology which applies the ultrasound well targeting, focusing, tissue absorbing property, and so on. It focused outer transducer low intensity ultrasound wave and targeted in the tumor, whichcan raise the temperature above 60℃ rapidly and induce tissue irreversible coagulation necrosis, with no damage to the surrounding normal tissue. It is a new physical tumor treatment technology.
