1. A planar phased ultrasound transducer, comprising:
a first layer including:
a sheet of piezoelectric material (PM), the sheet of PM including one or more kerf cuts, the one or more kerf cuts effective to form two or more transducer elements in the PM;
a piezo frame fully surrounding an outer perimeter of the sheet of piezoelectric material; and
an adhesive material placed between the piezo frame and the sheet of piezoelectric material; and
a flex frame secured to a back side of the first layer.
