Treating tumours using High Intensity Focused Ultrasound (HIFU) is one of the most promising emerging medical treatment methods within the last ten years worldwide.

In the seventies, clinical physicians found that tumour cells were more sensitive to temperature than normal cells. tumour cells die in abundance when their temperature is above 45 degrees Celsius. Researchers began to investigate the treatment of malignant tumours using heat. Ultrasound wave emission creates tissue movement (dilatation and contraction) which is converted into heat. This heat then kills the tumour cells. The advantages therefore are immediately apparent for the physician as the ultrasound

(1) can be tightly focused to the desired region,

(2) can enable heating of the desired region in a very short period of time,

(3) has no radiation injury risk.

Angel’s HIFU technology has been developed in conjunction with the China National Ultrasound Research Laboratory and the technology continues to be expanded and improved by its researchers and scientists today. Angel began first stage clinical trials in China in 2002. Successful and positive third stage clinical trials were completed at the end of 2005.
