Abstract: Systems and methods are provided whereby a directional property of an ultrasound transducer element, such as a steering direction, is controlled according to a first driving waveform that is delivered to opposing propagation electrodes and a second driving waveform that is delivered to opposing lateral electrodes. The directional property may be controlled according a phase difference and/or relative amplitude between the first and second driving waveforms, and/or the selective actuation of one or more lateral electrodes when the lateral electrodes are defined in an array. The ultrasound transducer element may be a ring-shaped transducer element and a directional property associated with a focal region may be controlled. In some example embodiments, array elements of an ultrasound transducer array may each include propagation and lateral electrodes, with each array element being driven by respective first and second driving waveforms to focus the ultrasound energy emitted by the ultrasound transducer array.

Abstract: Systems and methods are disclosed for performing ultrasound imaging using biphasic driving and/or reception for ferroelectric ultrasound elements having propagation and lateral electrode pairs. Electrode pairs are driven using biphasic drive signals, where the drive signals applied to the respective pairs of electrodes are provided with a phase difference therebetween, and where a time delay may be added between the drive signals to further increase the power of the emitted ultrasound. In some example embodiments, passive determination of the direction and/or location of an acoustic source relative to a multiaxial ultrasound transducer is determined based on the voltages detected at the propagation electrodes and the lateral electrodes the multiaxial transducer, according to a pre-determined relationship between the electrode voltages and one or more directional angles. A plurality of multiaxial ultrasound transducers may be employed to improve the accuracy of the estimated direction and/or location of the acoustic source.
