An imaging probe includes a transducer array with transducer elements (109) with parallel first and second planar surface (201, 203) in which an ultrasound signal is emitted from the first planar surface. A transducer element, includes a plurality of transducing sub-elements (208) arranged along an elevation direction in which adjacent transducing sub-elements are separated from each other by kerfs (212) of non-transducing material, wherein depths of the kerfs vary along the elevation direction.
