摘要： An ultrasonic transducer array for harmonic imaging including an ultrasonic transducer array having a plurality of transducer elements, each of said transducer elements having a first surface and a second surface opposite of said first surface, said second surface being non-planar in an elevation direction and said second surface facing away from a region of examination when the transducer is in use. Transmit circuitry is coupled to the transducer array and is operative to cause the transducer array to emit a signal having a bandwidth controlled such that substantially no harmonic energy is transmitted. Receive circuitry is coupled to the transducer array and selectively responsive to harmonic echo information.

摘要： The rate of decay of oscillations caused by application of driving pulses to the spaced crystals of an acoustic electric transducer that are mounted on a base is increased by making the thickness of the shield in contact with the ends of the crystals remote from the base such that asymmetrical Lamb waves flowing along the shield that can induce crystal oscillations in the thickness mode have a wavelength equal to twice the spacing between crystals so that their integrated effect is nearly zero.

摘要： A three crystal ultrasound transducer in which each crystal has a thickness that is measured in the z-range direction that varies as a function of its position along the x-elevation direction. The impedance of the transducer is reduced compared with uniform thickness transducers thereby providing a better electrical match between the ultrasound transducer and the ultrasound system to which it is coupled.

摘要： 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.

摘要： 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.
