When we use a magnifying glass to concentrate the rays of the sun, they burn only at the exact point at which they meet. In the same way, HIFU (High-Intensity Focused Ultrasound) technology focuses high-energy ultrasound to deliver a large amount of acoustic energy to a targeted area, quickly heating localised areas of tissue.
The energy of the ultrasound is concentrated in a small area. The energy released quickly raises the temperature in this area (to 80-95°C). This produces therapeutic effects through coagulation and then necrosis of the tissue in the targeted area.
Because HIFU is extremely precise, it has been used for many years in the treatment of tumours, destroying abnormal tissue through hyperthermia without affecting healthy tissue.
Echotherapy combines two categories of ultrasound: high-intensity focused ultrasound (HIFU) and the kind used in traditional ultrasound imaging. This combination enables accurate treatment of tumours, monitored in real time.
Echotherapy is an alternative to surgery and to minimally-invasive techniques, enabling non-invasive treatment of benign thyroid and breast tumours (fibroadenomas).
