摘要： A downhole ultrasonic transducer (10) used to transmit and/or receive ultrasonic waves in a hydrocarbon well where a fluid is present comprises: a metal housing (11) defining an internal cavity (12) isolated from the fluid of the hydrocarbon well (100) by a membrane wall (13) made of metal or metal alloy; a piezoelectric element (14) mounted inside the internal cavity (12), the piezoelectric element (14) having a front side (20) mechanically coupled on the membrane wall (13); wherein: the internal cavity (12) is at a pressure unrelated to a hydrocarbon well pressure; a back side (21) of the piezoelectric element (14) is arranged to be free to oscillate in the internal cavity (12) so as to generate a high acoustic impedance mismatch between the piezoelectric element (14) and the internal cavity (12) at the back side (21) and to maximize acoustic transmission at the front side (20); and a thickness (ei) of the membrane wall (13) is such that there is a common resonance between the membrane wall and the piezoelectric element thereby achieving high acoustic transmission through the membrane wall (13), and such that the membrane wall (13) is suitable to resist to the hydrocarbon well pressure.

摘要： An ultrasound transducer having an acoustic backing layer made of an aerogel material is disclosed. The ultrasound transducer comprises an acoustic element for transmitting and receiving ultrasound waves. An aerogel acoustic backing layer is bonded to the back side of the acoustic element. A matching layer may be attached to the front side of the acoustic element. The ultrasound transducer may be electrically connected using electrodes directly connected to the acoustic element. Alternatively, the aerogel acoustic backing may be coated with a metalized layer or doped so that it is electrically conductive. Then, the electrodes may be connected directly to the aerogel acoustic backing.

摘要： An ultrasound catheter is disclosed for providing substantially real-time images of small cavities. The ultrasound catheter is characterized by separate and distinct materials for backing the transducers and for carrying the electronics components. The separate materials comprise an electronics carrier meeting the requirements for holding the integrated circuitry of the ultrasound device and a backing material displaying superior characteristics relating to reducing ringing and minimizing the effect of other sources of signal degradation in the transducer assembly. Also, in accordance with the present invention, a technique is described for connecting the conductor lines of the separate transducer assembly and electronics body.
