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.
