Abstract

A phased array ultrasound apparatus comprises an array of ultrasound transducer elements (110); a plurality of first electrodes (132) and a plurality of second electrodes (134), such that each transducer element (110) is associated with one first (132) and one second electrode (134); wherein each transducer element (110) comprises a layer (118) of piezoelectric material between the first (132) and the second electrode (134) to induce emitting of an ultrasonic wave based on control signals, wherein control signals are shared by the transducer elements (110); wherein a phase of an emitted ultrasonic wave differs 180° between two polarization states of the piezoelectric material; and wherein the phased array ultrasound apparatus (100) is configured to individually change polarization state of the piezoelectric material of selected ultrasound transducer elements (110) before activating at least a subset of the ultrasound transducer elements (110) in the array to form a combined ultrasonic wave.
