项目摘要
We have developed an active magnetic shield using a pair of magnetic shells of half cylindrical structure made of amorphous tapes and FRP composite. Active compensation technique to expel magnetic noises coming from outside has beendeveloped. We have also developed a wide-band, high resolution magnetic sensor andlow-noise power amplifiers for the compensation system. We applied the said shield for the MCG measurement by a SQUID system and, for the first time, by a fluxgate sensor array of 6 channels. A method has been developed by which accumulated location of magnetic markers in a phantom can be identified by mapping magnetic fields in the developed magnetic shield.
我们使用了由无形磁带和FRP复合材料制成的半圆柱结构的一对磁性壳开发了一个主动磁屏蔽。积极的补偿技术以排出来自外部的磁噪声已被逐渐开发。我们还为补偿系统开发了一个宽带,高分辨率的磁性传感器Andlow-Noise功率放大器。我们通过鱿鱼系统将上述盾牌应用于MCG测量,并首次通过6个通道的FluxGate传感器阵列。已经开发了一种方法,可以通过绘制开发的磁性盾牌中的磁场来识别磁标记的累积位置。
