Abstract

본 발명에 의한 3차원 초음파 이미징을 위한 2차원 가상 배열형 탐촉자는, 초음파 트랜스듀서; 복수 개의 도파관이 2차원 배열된 초음파 방사면과, 상기 초음파 트랜스듀서로부터 방사되는 초음파를 그 내부에서 불규칙(chaotic)하게 반사 시키기 위한 1/8 구(sphere)형상의 홈부를 가지는 금속재질의 탐촉자 몸체; 피검사체와 접촉하도록 상기 초음파 방사면 상측에 배치되어, 상기 탐촉자로부터 방사된 초음파는 상기 피검사체 측으로 통과시키고, 상기 피검사체로부터 반사된 초음파를 감지하여 신호를 출력하는 압전 시트부재(piezoelectric sheet); 및 상기 복수 개의 도파관이 순차적으로 초음파를 발진하도록 상기 초음파 트랜스듀서를 제어하는 제어부;를 포함하는 것을 특징으로 한다.
