HIFU beams are precisely focused on a small region of diseased tissue to locally deposit high levels of energy. Focused ultrasound may be used to generate highly localized heating to treat cysts and tumors (benign or malignant). This is known as Magnetic Resonance guided Focused Ultrasound (MRgFUS) or High Intensity Focused Ultrasound (HIFU).
The focused ultrasound waves generate high temperatures within smaller areas. The temperature when maintained for sufficient a period of time results in the ablation of the fibroids. The therapy procedure is guided by Magnetic Resonance Imaging (MRI) with real time feedback, which helps in the focused ablation of the target location. [3]
Ultrasound can ablate tumors or other tissue non-invasively. [4] This is accomplished using a technique known as high intensity focused ultrasound (HIFU), also called focused ultrasound surgery. This procedure uses generally lower frequencies than medical diagnostic ultrasound (250–2000 kHz), but significantly higher time-averaged intensities.
Haifu is a medical device manufacturer, producing High-intensity focused ultrasound (HIFU) equipment. The HIFU machines produced are CE certified. [ 3 ] The company sells in foreign markets and was noted in a China Daily article as an example of Chinese businesses manufacturing goods of higher sophistication for the international market.
Focused-ultrasound-mediated diagnostics or FUS-mediated diagnostics are an area of clinical diagnostic tools that use ultrasound to detect diseases and cancers. Although ultrasound has been used for imaging in various settings, focused-ultrasound refers to the detection of specific cells and biomarkers under flow combining ultrasound with lasers, microbubbles, and imaging techniques.
In guided therapy, high-intensity focused ultrasound (HIFU) beams are focused on a tissue, that are controlled using MR thermal imaging. Due to the high energy at the focus, the temperature rises to above 65 °C (150 °F) which completely destroys the tissue.

Of the existing ultrasound modalities, focused ultrasound has been used extensively in drug delivery research. [33] [34] High-Intensity Focused Ultrasound (HIFU) and Low-Intensity Focused Ultrasound are the two main techniques used in inducing drug release from smart hydrogels. [43]
