Working Principle
The working principle of high intensity focused ultrasound treatment is to focus the ultrasound, penetrate into the human body, and eliminate the tumor tissue through a series of composite effects. Just as sunlight can be focused through a convex lens, ultrasound can also be focused, and can safely penetrate the body, gather ultrasound with low energy density to the tumor site in the body, and use the thermal effect of ultrasound at the focus to form a high temperature above 60 ℃ in the target area, resulting in protein degeneration, tissue and cell coagulation necrosis or irreversible serious damage, So as to achieve the purpose of treating tumor. In addition, dead tumor cells and tissues release antigens, which may activate the body's immune system and enhance the body's immune effect.
