The development and application of high intensity focused ultrasound in biomedical ultrasonics

High intensity focused ultrasound as a nondestructive method without side-effects for tumor therapy has attracted wide interest. The theory is based on the focusing of low-energy ultrasound onto the desired region in the body in order to raise the tumor temperature to above 65℃, thereby inducing ablation. China is among the foremost in thisfield, including clinical application. The history and development of high intensity focused ultrasonics is reviewed.
