Claims (1)

  1. 압전 소자를 사이에 두고 한쪽에 복수의 분할구동전극이 열상(列狀)으로 배치되고, 이것과 대향되는 면에 접지전극이 배치된 전동자로 구성되는 초음파 프로우브를 구비하고, 이 분할구동전극에 차례로 전기시호를 인가함으로서 초음파 비임을 제어하는 초음파 진단장치에 있어서, 상기 접지 전극을 상기 열상으로 배치된 분할 구동전극에 대하여 교차하는 방향으로 배치된 복수개의 분할전극으로 하고, 각 분할전극을 상호 관련성을 지니도록 구동함으로서 초음파 비임의 X,Y축 방향의 지향성을 제어하도록 한 것을 특징으로 하는 초음파 진단장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
