The present disclosure relates to an ultrasound transducer having at least one transducer element for sending or receiving ultrasound signals. The ultrasound transducer includes a matching element acoustically coupled to the transducer element that is designed to ensure acoustic matching between the transducer element and a medium that acts on the matching element. In a first subregion of the axial extent, the matching element partially fills each cross section of the matching element, and a filling component in the first subregion along the first longitudinal axis monotonically increases in the direction of the first side. The matching element has a plurality of ring elements in the first subregion arranged concentrically around the first longitudinal axis. Each ring element partially fills each cross section in the first subregion, wherein the first subregion comprises at least 80% of an axial extent of the matching element along the first longitudinal axis.
