Abstract
Ultrasonic phased arrays are capable of producing both single or multiple focus field patterns in the patterns in the treatment volume. A circular phased array applicator used to produce the desired power deposition and temperature distributions in a multilayered concentric cylindrical model is discussed. The driving signals of the phased array are obtained by the pseudoinverse technique. The temperature distributions obtained show that this type of phased array is capable of generating heat levels suitable for cancer therapy
