Intense focused ultrasound

Mathjax On | Off Abstract Intense focused ultrasound (IFUS) has recently emerged as a potential noninvasive alternative treatment for tissue tightening. It works via the deposition of acoustic energy, which creates movement of molecules and leads to the generation of thermal and focal tissue damage. It creates inverted conical-shaped zones of heat coagulation of approximately 1 mm3, with a depth of penetration of up to 4.5 mm depending on the setting used.
