摘要： A medical diagnostic ultrasound transducer system for harmonics is provided to receive the harmonics generated by interaction of the multiple frequencies for wide band imaging, by simultaneously transmitting at multiple center frequencies or frequency bands. An acoustic signal having at least first and second different frequency bands is generated according to a broadband electrical signal. The acoustic signal is generated by a first set of transducer layers(20,22) of an element(14) having at least first and second transducer layer along a range dimension. An electrical signal is received at a harmonic or harmonic interaction frequency of the first and second frequency bands. The receiving is performed by a second set of transducer layers which is one or more transducer layers and is different than the first set.
