摘要： An ultrasound probe and an ultrasound diagnosis apparatus that can acquire 3-D ultrasound image data of a wide viewing scope including both a diagnosis portion and peripheral portions of the diagnosis portion by swinging a transducer unit in an orthogonal direction to an array of a plurality transducers in the transducer unit without sacrificing the operability of the ultrasound probe.The ultrasound probe includes a transducer unit having a plurality of transducers, an arm for holding one edge of the transducer unit so as to be extendable in a longitudinal direction, a rail body for holding the other edge of the transducer unit and a driving unit for driving the transducer unit along the rail body. The rail body is comprised of a main rail member having a first curvature in order to form a main track and at least one sub-rail member having a second curvature being larger than the first curvature for forming at least one sub-track.

摘要： The ultrasound probe according to the present embodiment comprises ultrasound oscillators configured to transmit and receive ultrasound waves, an intermediate layer configured to have greater acoustic impedance than the ultrasound oscillators, a backing material configured to support the ultrasound oscillators, and a buffer layer. The ultrasound oscillators, the intermediate layer and the backing material are disposed in that order of the ultrasound oscillator, the intermediate layer and the backing material. The buffer layer, which has smaller acoustic impedance than the intermediate layer and the backing material, is disposed between the intermediate layer and the backing material.

摘要： A flexible printed circuit board, interposed between an intermediate member and a backing material, covers an almost whole back face of the intermediate member and has first and second wiring patterns. A first electrode is interposed between the piezoelectric transducer and the intermediate member, extracted onto the side face of the intermediate member contiguous with one side face of the piezoelectric transducer, and electrically connected to the first wiring pattern. A second electrode is formed on the ultrasound transmission face of the piezoelectric transducer, extracted by being routed on the other side face of the piezoelectric transducer and a side face of the intermediate member contiguous with the other side face of the piezoelectric transducer, and electrically connected to the second wiring pattern.

摘要： According to one embodiment, an ultrasonic probe includes a transducer element, a backing material, and a buffer layer. The transducer element vibrates to transmit and receive an ultrasonic wave. The buffer layer is provided on the back side of the transducer element. The backing material is provided on the back side of the buffer layer and damps an ultrasonic wave from the transducer element. The buffer layer has a Poisson ratio larger than that of the backing material.

摘要： A ultrasonic probe has a plurality of piezoelectric transducers arranged in the array direction. Each piezoelectric transducer has a piezoelectric element which vibrates in the thickness direction. A signal electrode is formed on the lower surface of the piezoelectric element. An earth electrode is formed on the upper surface of the piezoelectric element. Inside the piezoelectric element, a plurality of non-piezoelectric elements are arranged along the lens direction. Each non-piezoelectric element does not come in contact with the signal electrode and the earth electrode.
