PROBLEM TO BE SOLVED: To provide an ultrasonic probe including a matching layer providing conductivity by forming an electrode in the matching layer, and a manufacturing method thereof.SOLUTION: An ultrasonic probe includes a piezoelectric layer and at least one matching layer 10 which is positioned on a front face of the piezoelectric layer and in which an electrode is formed. Furthermore, when forming an internal electrode 13 within the matching layer, a plurality of kerfs 11 on one surface of the matching layer, electrodes 12, 13 are formed on the one surface of the matching layer including an inner surface of the plurality of kerfs, the plurality of kerfs are filled, and one surface side and another surface side of the matching layer are cut, thereby exposing the electrodes formed on the inner surface of the plurality of kerfs. Moreover, after the one surface side and the other surface side of the matching layer are cut so as to expose the electrodes, an external electrode 15 is further formed on the one surface and the other surface of the matching layer where the electrodes are exposed.

PROBLEM TO BE SOLVED: To provide an ultrasonic probe including a sound absorption layer where a groove enabling a piezoelectric layer to be installed therein is formed, and to provide a manufacturing method of the ultrasonic probe.SOLUTION: An ultrasonic probe comprises: a piezoelectric layer 20; and a sound absorption layer 30 positioned on a rear surface of the piezoelectric layer, the sound absorption layer 30 where a groove 31, allowing the piezoelectric layer to be installed, is formed on a front surface. The piezoelectric layer 20 is formed by multiple elements processed into a form of one of one dimensional array and two dimensional array and forms a ground electrode on at least one surface of the elements and a signal electrode on at least one surface including a surface opposite to the surface where the ground electrode is formed. The groove 31 is formed in the same form as the piezoelectric layer 20.
Abstract:
The present invention is directed to an ultrasound system. The ultrasound system of the present invention includes an ultrasound diagnostic unit (150), a storage unit (130), an image acquisition unit (110), a pattern recognition unit (120), and a control unit (140). The ultrasound diagnostic unit forms an ultrasound image representative of a target object. The storage unit stores training sets in association with respective instructions for operating the ultrasound diagnostic unit. Each of the training sets includes pattern samples associated with a particular action of a user. The image acquisition unit acquires an action of a user to form an action image. The pattern recognition unit recognizes an action pattern from the action image. The control unit retrieves the training sets stored in the storage unit to find a pattern sample having a match with the recognized action pattern. The control unit controls an operation of the ultrasound diagnostic unit based on an instruction associated with the training set including the found pattern sample.
