摘要： Various approaches for detecting microbubble cavitation resulting from ultrasound waves transmitted from an ultrasound transducer include associating at least one time-domain reference signal with microbubble cavitation; causing the transducer to transmit one or more ultrasound pulse; acquiring, in the time domain, an echo signal from microbubbles in response to the transmitted ultrasound pulse(s); correlating at least a portion of the echo signal to at least a corresponding portion of the time-domain reference signal based on similarity therebetween; and detecting the microbubble cavitation based on the corresponding portion of the reference signal.

摘要： Method for adjusting the output of a phased array ultrasonic transducer using surface mapping. The transducer surface is mapped using a sensor, such as a hydrophone, to determine the actual location of each transducer element relative to the expected location of each transducer element. Mapping can be performed by measuring a distance between a hydrophone and each transducer element. At least one of the hydrophone and the transducer are moveable relative to each other to map the transducer surface. A determination is made whether the actual location of a transducer element differs from the expected location. Drive signals of certain transducer elements having actual locations that differ from expected locations are adjusted to control the output of the transducer.

摘要： Transducer elements have one or more asymmetric features that give rise to multiple natural resonance frequencies. The feature(s) can be discrete (e.g., steps, bars, or gemstone-like facets) or continuous across one or more dimensions of the transducer element (e.g., a triangular prism). A transducer element can be driven at more than one resonance frequency; multiple frequencies will excite more than one feature in parallel, each producing an output emission with a characteristic frequency and phase. An optimal frequency—i.e., one that maximizes the peak acoustic intensity or acoustic power at the target—within a certain frequency range may be determined, and a plurality of asymmetric transducer elements may be driven at a center frequency that coincides with or is close to this optimal frequency.

摘要： Ultrasound energy is delivered to a patient in a controlled manner using a focused ultrasound system, thus maintaining the desired therapeutic effect without causing unwanted damage to surrounding tissue. An ultrasound transducer device includes multiple transducer elements, each of which is controlled by drive circuitry and a drive signal controller. An acoustic detector detects signals indicative of cavitation in tissue targeted by the transducer elements, and the drive signal controller manages the delivery of acoustic energy from the transducer elements based on the detected cavitation signals such that a therapeutic effect at the target tissue remains within an efficacy range.
