Abstract

Disclosed are methods of obtaining zero vergence ultrasound waves for providing sonodynamic therapy with ultrasound waves that do not converge and do not diverge. The method includes coupling a sonodynamic therapy device with an array of flat piezoelectric transducers to a skin surface. A controller is configured to generate an electrical drive signal at a frequency, modulate the drive signal, and drive the transducer with the modulated drive signal at the frequency to produce a zero vergence ultrasound wave to produce an average acoustic intensity sufficient to activate a sonosensitizer in a treatment region without damaging healthy cells in the treatment region.
