What is HIFU and its working principles

High intensity focused ultrasound (HIFU) is a new type of tumor therapy. When using this method to treat tumors, we can use ultrasonic positioning and high-intensity ultrasound to kill tumor cells in the target area without damaging the surrounding normal tissues, so as to realize the minimally invasive treatment of tumor tissues.

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.
