Abstract: PROBLEM TO BE SOLVED: To provide a converter element array, and its manufacturing method, in which acoustic characteristics and sensitivity are improved, bandwidth is increased and focus characteristics are enhanced. SOLUTION: Each converter element (12) comprises a piezoelectric layer (22) and one or more sound matching layers (24, 26). The piezoelectric layer (22) has a concave front surface covered with a front electrode (42) and a rear surface covered with a rear electrode (40). Shape of each converter element (12) is selected such that the focal point is located mechanically on the imaging plane. A lining support (80) keeps a specified relation among the plurality of converter elements (12) along the array axis (A) such that each element (12) is focused mechanically on the imaging plane.

Abstract: An ultrasonic transducer array, and a method for manufacturing it, having a plurality of transducer elements aligned along an array axis in an imaging plane. Each transducer element includes a piezoelectric layer and one or more acoustic matching layers. The piezoelectric layer has a concave front surface overlayed by a front electrode and a rear surface overlayed by a rear electrode. The shape of each transducer element is selected such that it is mechanically focused into the imaging plane. A backing support holds the plurality of transducer elements in a predetermined relationship along the array axis such that each element is mechanically focused in the imaging plane.
