Abstract
Various approaches for focusing an ultrasound transducer include introducing at least one transient acoustic reflector located in proximity to at least one target region; generating multiple sonications to the at least one target region; measuring a reflection signal of each of the sonications off the at least one transient acoustic reflector; selecting the measured reflection signals, and based at least in part on the selected reflection signals, adjusting a parameter value associated with at least one of the transducer elements so as to improve an ultrasound focus at the target region.
