Paper Abstract

Practical high power phased arrays have been developed and tested in our laboratory. The results show that they offer significant advantages over conventional single focused ultrasound transducers for noninvasive ultrasound surgery. These advantages include but are not limited to: compensation of phase distortion induced by overlying tissues, potential for inducing optimal energy delivery patterns, and generation of large focal spots for tumor coagulation. This paper will describe some of our results with the therapy phased array.
