Focused ultrasound system with cavitation optimized monitoring

摘要

Using an ultrasonic transducer having a plurality of transducer elementsThe ultrasonic focus is generated in the target region.Various approaches for receiving signals from there areTarget regionObtaining multiple images of one or more path areas located on the beam path between the transducer element and the target region;Based on the image obtainedDetermining one or more tissue characteristics associated with the target regionAt least partiallyBased on the determined organizational characteristicsDetermining a plurality of profile parameters associated with each of the transducer elements andAt least partiallyBased on the profile parameterOperate at least the first element of the transducer elementCollectivelyThe ultrasonic beam is transmitted to the target regionAndCreate a focus with the desired nature on it;Including improving the focus in the target region.
