초록

최근 안과 또는 피부과의 의료진단분야에 도입하기 위한 수십 μm 이하의 높은 공간분해능을 갖는 수십 MHz 대역의 초음파 트랜스듀서에 대한 연구가 활발히 수행되고 있다. 본 해설에서는 그 연구의 배경 및 트랜스듀서의 구조와 특성, 그리고 그것을 이용하여 얻은 영상에 대하여 간략하게 소개하였다.

Recently, ultrasound transducers in several tens MHz band, which can give the spatial resolution higher than several tens micrometers, have been intensively studying for applying to medical diagnostic fields of ophthalmology and dermatology. In this paper, the background of the studies, structures and characteristics of the transducers, and images obtained by the transducers are briefly reviewed.
