Abstract
Disclosed are methods of using planar acoustic waves for providing non-invasive sonodynamic therapy. The method includes acoustically coupling an array of flat piezoelectric transducers to a patient. A controller is configured to generate an electrical drive signal at a frequency selected from a range of frequencies, modulate the drive signal, and drive the transducer with the modulated drive signal at the frequency to produce a modulated planar acoustic wave to produce an average acoustic intensity sufficient to activate a sonosensitizer in a treatment region without damaging healthy cells in the treatment region.
