Abstract
Various approaches for focusing an ultrasound transducer having multiple transducer elements include causing the transducer elements to transmit ultrasound waves to a target region and measure reflections of the ultrasound waves off the target region; for each of at least some of the transducer elements, adjusting a parameter value associated with said each transducer element based at least in part on parameter values associated with multiple measuring transducer elements weighted by signal quality metrics associated with the reflections measured by the measuring transducer elements so as to improve an ultrasound focus at the target region.
