Abstract
Various approaches to delivering ultrasound energy to a target region include an ultrasound transducer having multiple transducer elements for generating a focal zone of acoustic energy at the target region, wherein one or more transducer elements are partitioned into multiple contiguous sub-regions having a common directionality; one or more driver circuits connected to the transducer element(s); a switch matrix having multiple switches for switchably connecting the sub-regions to the driver circuit(s), each of the sub-regions being associated with one of the switches; and a controller configured to (i) determine an optimal sonication frequency for maximizing a peak acoustic intensity in the focal zone; and (ii) based at least in part on the determined optimal sonication frequency, activate one or more switches in the switch matrix for causing the corresponding sub-region(s) to transmit ultrasound pulses to the target region.
