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.
