The phased array, which is as an attracted transducer for tumor therapy of high-intensity focused ultrasound (HIFU), can be used for controlling of the acoustic field using pseudoinverse algorithm. The programming was interminable and the computing time consumed greatly because of the complicated expression of location-controlling function in this algorithm. An improved pseudoinverse algorithm was employed to simulate the acoustic field produced by a phased array comprised of 10 ×10 square elements when the tumor lay in different depth in mult...
