ABSTRACT:
A phased array transducer and method for the manufacture thereof having a design that allows the array to focus in a near field of interest and a far field of interest. The array includes a plurality of even and odd numbered transducer elements where the even and odd numbered elements have an active region of particular widths. The width of the active region of the odd numbered elements is different than the width of the active region of the even numbered elements so that the odd numbered elements can be used to image in one field of interest while the even numbered elements can be used to image in another field of interest.
