Disclosed are methods of producing ultrasound waves for providing sonodynamic therapy. The method includes coupling a sonodynamic therapy device with an array of piezoelectric transducer elements to a skin surface. A controller is configured to generate an electrical drive signal to produce ultrasound waves to activate a sonosensitizer in a treatment region without damaging healthy cells in the treatment region.
