Abstract

See full text

A transducer system and method for harmonic imaging is provided. At least one transducer element is provided. The transducer element comprises two or more stacked piezoelectric layers. Information from each of the layers is independently processed during one of a transmit event, a receive event, and both transmit and receive events. Information from the transducer element is provided to a filter. The filter isolates harmonic information for imaging. By providing a multi-layer transducer element with independent processing for each layer, a wide bandwidth transducer for harmonic imaging is provided. The null associated with most transducers at the second harmonic of a fundamental frequency is removed or lessened.
