Synthetic phase alternating row-column transducer array

Abstract

An ultrasound array system has an array of transducer elements made from bias-sensitive material, each transducer element comprising at least a first sub-element and a second sub-element. A series of column electrodes is patterned in columns on a first surface of the array of transducer elements. A series of row electrodes is patterned in rows on a second surface of the array. The rows are at an angle relative to the columns, wherein, for each transducer element, the first sub-element and the second sub-element are connected to different row electrodes. A controller is connected to selectively apply voltage signals to the series of column electrodes and the series of row electrodes. The controller is programmed to apply a first voltage signal to the first sub-element and a second voltage signal to the second sub-element that is distinct from the first voltage signal.
