US Patent 8208346 Selectable tuning transformer

An assembly and method for assembling a tuning transformer (104) and printed circuit board (PCB) (108) to a transducer (110) to produce a tuned ultrasound transducer (100). The tuned ultrasound transducer allows a transducer to be made with some degree of inconsistency in its impedance magnitude and phase, but each transducer, when configured and coupled to a tuning transformer assembly, produces a signal that is substantially homogeneous.
