Sonodynamic therapy systems and methods use short, high-pressure ultrasound pulses that produce small (and therefore clinically safe) increases (up to 1-2° C.) in tissue temperature but nonetheless activate sonodynamic agents, allowing isolated single-cav-itation events to produce therapeutically beneficial effects (e.g., cytotoxicity) on diseased tissue. An escalating sonication strategy may be employed whereby the focal pressure is gradually increased until maximum clinically tolerable parameters such as the degree of heating of intervening tissue (e.g., the skull when treating brain cancer) or undesired induced cavitation effects are reached.
