Beschreibung
Zusammenfassung:	An ultrasonic transducer particularly useful in medical imaging includes a transducer comprising a transducer body having a major front surface for radiating ultrasonic energy to a propagation medium responsive to mechanical vibration of the transducer. The transducer includes a piezoelectric member having a curved shape including a curved front surface. The curved shape is produced by deforming a planar piezoelectric composite member to produce the desired curvature and returning the curvature using suction forces. A graded frequency region is created by grinding the curved front surface of the piezoelectric element along a grinding plane. This region is defined by the area of intersection of the grinding plane and the front surface of the curved piezoelectric member and in different implementations, covers all or less than all of the total front surface.
