HIFU (High Intensity Focused Ultrasound)

HIFU (high intensity focused ultrasound) heats and destroys pathogenic tissue rapidly by using a high-intensity, focused ultrasound. This highly precise medical procedure is one modality of therapeutic ultrasound. The ultrasound beams in HIFU therapy target diseased tissue, and from the significant energy deposition at the target, temperature within the tissue rises from 65° to 85°C, thus destroying the diseased tissue by coagulation necrosis. Because this technology can achieve precise ablation of diseased tissue, it can therefore be called HIFU surgery. Since it destroys the diseased tissue non-invasively, it is also known as "Non-invasive HIFU surgery". Anesthesia typically is not required.

High Intensity Focused Ultrasound is considered a promising technology due to the non-invasive or minimally invasive therapy. HIFU’s capacity to generate in-depth precise tissue necrosis, with no effect on the surrounding structures, is unique. Technology has continually improved and additional clinical applications, both diagnostic and therapeutic, have become an integral part of medicine today. HIFU differs from many other forms of focused energy due to the passage of ultrasound energy through intervening tissue has no apparent cumulative effect on that tissue.
