Abstract

A magnetic field detector as a potential MRI receiver is proposed. The proposed device is composed of SRR(split ring resonator) which is a kind of LC resonator first introduced as a negative permeability material and a simple loop antenna. The proposed device showed similar degree of performance to commercial one with a simpler circuit.

MRI(magnetic resonance imaging)의 신호검출기로 활용 가능한 간단한 형태의 자기장 검출기를 제안하였다. 제안된 검출기는 SRR(split ring resonator)이라고 하는 음의 투자율을 구현하는데 최초 사용되었던 일종의 LC 공진회로와 간단한 루프안테나를 유도성 결합시킨 것으로 기존의 MRI 신호검출기에 비해 단순한 구성으로 유사한 감도를 가질 수 있음을 확인하였다.
