Abstract :
In this article, the construction and functions of ultrasound-guided 256-element phased-array surgery system is described. An image-guided phase array therapy system has been developed. Several flexible multifocus control methods for accurate, highly efficient, and fit-to-shape ultrasound surgery are concentrated. The system experiment results show that the multiple foci are positioned exactly at designed locations. In addition, the experiment results agreed well with the simulations.
