PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic device which can improve the image diagnosis ability by resolving a problem of attenuation.SOLUTION: There is provided an ultrasonic probe in which vibrators are arranged in a matrix so that the ultrasonic waves from the vibrators are made to interfere with each other for mutual enhancement. The ultrasonic waves emitted from the plurality of vibrators are transmitted into a body while interfering with each other, and the vibrators receive the reflection waves. By utilizing the ultrasonic waves enhanced by intentionally interfering with each other, the reflection waves with the sufficient intensity can be obtained even in a deep part of a human body, and the image diagnosis ability is improved.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】減衰する問題を解消し、画像診断能の向上を可能とする超音波診断装置を提供する。【解決手段】複数の振動子からの超音波を互いに干渉させて強めあうように、振動子をマトリクス状に配置させた超音波プローブとする。複数の振動子から発信された超音波は、互いに干渉しながら体内に伝わり、その反射波を振動子が受信する。意図的に干渉させて強めた超音波を利用することで人体の深部でも十分な強さの反射波を得ることができ、画像診断能が向上する。【選択図】図１
