Description

초음파 진단장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 구형 진동자의 지향성을 설명하기 위한 도면.
제2도는 구형진동자에서 초음파를 송신한 경우의 지향특성을 나타낸 도면.
제3도는 피검체내 각 거리에 있어서의 필터출력의 스펙트럼에 대한 중심주파수를 표시한 도면.

Claims (2)

  1. 복수개의 초음파 진동자를 어테이상으로 배열하고, 일부 또는 모든 초음파 진동자에 지연 시간을 부어하여 송수신 하므로서 초음파 비임의 편향을 행하는 초음파 진단 장치에 있어서, 수신한 초음파에 대해 피검체의 심도 깊이에 응한 음압 보정과 동시에 초음파 비임의 편향각에 응한 음압 보정을 행하는 음압 보정 수단을 갖는 것을 특징으로하는 초음파 진단 장치.
  2. 복수개의 초음파 진동자를 어레이 상으로 배열하고, 일부 또는 모든 초음파 진동자에 지연시간을 부여하여 송수신하므로서 초음파 비임의 편향을 행하는 초음파 진단 장치에 있어서, 수신된 초음파 에코우에 의한 에코우 신호에서 소정의 주파수 성분을 잡아내는 대역통과 필터와 상기 대역통과 필터의 중심 주파수를 초음파 에코우에 대한 편향각에 응하여서 가변하는 필터 제어 회로를 구비하여, 근거리 음장에서의 음압 열화에 의한 신호 강도의 저하를 방지하는 것을 특징으로 하는 초음파 진단장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
