Abstract :
Compared with a single-frequency system, the multiple-frequency system has an additional function to combine power patterns of different frequencies. This function increases the availability of power patterns to treat various shapes and depths of tumors. Therefore, we proposed a system with the ability to drive ultrasonic phased arrays of multiple resonant frequencies for ultrasound hyperthermia
