Abstract
There is provided a broadband transducer array for use in an acoustic imaging system having a plurality of transducer elements disposed on a preformed support. The support has a non-planar top surface on which are disposed a plurality of elevationally curved transducer elements. Kerfs separate each transducer element from one another. The depth of the kerf with reference to the non-planar top surface of the support may be uniform or non-uniform.
