WebThe Principle of HIFU. High Intensity Focused Ultrasound (HIFU) uses an ultrasound probe to deliver high-intensity sound waves at a precise point. The magnitude of ultrasound energy delivered rapidly raises the temperature at the focal point, causing coagulation necrosis without damaging healthy tissue and structures outside the targeted area. WebUltrasound, like any wave, carries energy that can be absorbed by the medium carrying it, producing effects that vary with intensity. When focused to intensities of 10 3 10 3 to 10 5 10 5 W/m 2 W/m 2 , ultrasound can be used to shatter gallstones or pulverize cancerous tissue in surgical procedures.
