초록
바이오 메디컬 이미징 기술은 생물학적 연구 및 의료 기술에 사용되는 이미징 기법들을 말하며, 생물학적 과정, 구조 및 상태를 탐구하는 데필수이며, 질병의 조기 진단과 치료법 개발에도 중요한 역할을 하고 있다. 그중에서도 특히 빛을 이용한 광학 이미징 기술은 생물학 연구에서 가장 많이 활용되고, 활발하게 연구되고 있다. 광학 이미징 기술의 발전에서 가장 큰 걸림돌이 되고 있는 것은 해상도 및 빛의 투과 깊이 한계 등인데, 최근에는 메타물질을 이용하여 이를 해결하고자 하는 연구가 활발해지고 있는 추세이다. 메타물질은 나노구조체의 규칙적인 배열을 통해 빛의 성질을 자유롭게 조절하는 물질로서, 이미징 분야에서는 이미 혁신적인 도구로 자리잡고 있다. 이 글에서는 메타물질을 활용한 광학 이미징 기술의 작동 원리와 주요 응용 사례에 대해 자세히 소개하고자 한다.
Abstract
Biomedical imaging technologies refer to imaging techniques used in biological research and medical technology that are essential for exploring biological processes, structures, and conditions. They also play a crucial role in the early diagnosis of diseases and the development of treatments. Optical imaging technologies, in particular, are the most widely used and actively researched in biological studies. The major obstacles to technological advancement are the limitations in resolution and light penetration depth. Recently, many technologies have been studied to overcome these limitations using metamaterials. These are materials that can freely manipulate the properties of light through the regular arrangement ofnanostructures and have established themselves as innovative tools in the imaging field. This article aims to provide a detailed introduction to theworking principles and key applications of these technologies.
